Digitalisation used to be our entertainment. Now, digitalisation comes to the workplace. Not only because of the COVID-19 epidemic but also because of its versatility and applicability.

Why do we need to put our task into digitalisation? Digitalisation used to be our entertainment. Now, digitalisation comes to the workplace. Not only because of the COVID-19 epidemic but also because of its versatility and applicability.

The world shifts to digitalisation to reach widespread communication. Environmental practitioners possess pieces of knowledge; digitalisation transforms the experience into a digestible presentation. The challenge is for us to adopt and combine all the expertise into one. 

In practical terms, a digital working environment facilitates connection, enhances intelligence and versatility, encourages transparency, embraces collaboration and mobility, attains productivity, allows fair-minded and inclusion, and improves accuracy. 

The digitalised workflow guides us throughout the discipline. Company culture and technology interact with digital working principles. At the back end, data management, quality, and standards are essential to ensure integrity. Effective communications lead to accessibility for all needs while maintaining security and confidentiality. 

Digitalisation does not merely mean converting records of text, image, or sound into a format that computers can process. The need for workflow improvement directs to an automated operation. Automation is not to replace humans, but to enhance our work efficiency and accuracy.

An automated monitoring system supported by a technology platform empowers authorised parties to operate through various IT devices, including smartphones and tablets. The system automatically signals the breaches and verifies the sources. All data is filed and immediately accessible for use. The system contributes substantial savings in human resources and costs for site monitoring works and enhances information distribution amongst project parties.

By applying to the vibration field, vibration monitoring systems can manage multiple vibration sources. Powered by state-of-the-art information technology, vibration monitoring systems provide the users with a multimedia platform for timely reporting and productive communication among contractors, environmental teams, inspectors, project proponents, the Authorities, and the managers of the vibration sources. The system is designed to comply with regulations and standards; The system will perform compliance checks throughout the monitoring process. 

Proper monitoring management means so much for human lives in specific functional applications. In the age of digitalisation, we are leveraging automation into the environmental area, reshaping our modern approach in environmental monitoring.

What instrument do we need for noise measurement?

Humans hear because our ears function to allow us to feel the vibration of the sound power emitted from the source object. Therefore, we need an instrument that hears the way we do for noise monitoring. This is the sound level meter. The weighting network built-in in the sound level meter will function to weigh. It is working like our ears, which emphasises or weighs some parts compared to others.

Photo above: Norsonic sound level meter

In the world of digitalisation, we fully utilise the Internet and website to conduct monitoring. The noise data collected by the sound level meter will be transferred via the Internet. We will make good use of the dashboard to view the data collected online. The digitalisation saves the human resources we used to need for monitoring. We can now easily retrieve the data in real-time and the historical records.

What kind of data should we record? First and foremost, the dB of our monitored environment. The corresponding date and time are to let us find out when the particular event happens. And this is the reason why we need historical data over a period. Additionally, we may want to know about the weather condition as the rainy day may force us to abandon the monitoring for the rain splash sound. Sometimes, you want to monitor the sound levels at several locations. A station list with the map embedded on the dashboard is a helpful tool to reveal which station you are reviewing.

You have learned about the critical elements of noise measurement. Now, let’s act together – Observe your environment; Identify the noisy areas you would like to monitor; Know your noise monitoring device; Set up the noise monitoring station; Learn the dashboard to record the data; Brief about noise monitoring factors and mitigation measures. Study the noise in your environment for a period. You will find out the characteristic of your place and think about what to do.

We bear a responsibility to protect and improve the environment. Can you think of a way of creativity to deal with the noise problem you have? Any thought about utilising a noise absorption material to design the mitigation with aesthetics in mind?

How can you correctly measure noise?

You may be engaged in noise measurements in a workshop, measuring with all objects running simultaneously. If you stay there, you will get the data for all objects and the overall sound pressure level in the room. In many cases, background noise may drown out the particular machine noise during measurement. How do you eliminate the background noise and correct the influence?

What you need to do is to measure the sound pressure level with the objects running, and then switch off the objects and measure the background level, calculate the difference between these amounts, locate this on the horizontal axis on the graph below, go up until you intersect the graph, and then go to the vertical axis to the left. Subtract this value from the overall level, and you get the machine sound pressure level. Alternatively, you can utilise the equation to get the result.

Background noise matters to our noise measurement. Before measurement, we have to observe the environment to measure the noise level and identify the ideal location of the monitoring station. There are numbers of points we need to pay attention to when observing the environment. How many noise sources can you find in the environment? What characteristics do the noise sources have? Which location at the site can we pinpoint most of the noise sources? At the site, which directions do the noise sources come from? How far apart are the noise sources? Are there any walls/structures that may cause reflection?

Besides background noise, external factors such as the angle of the sound level meter are placed, and the weather impacts the monitoring. Do we cover most of the noise sources? Is the station close to the noise sources? Is the area encountering human activities? Do we have a good wifi signal and a stable electricity supply? Last but not least, is it safe to access?

After identifying the monitoring location, let us find out what instrument we need for noise measurement.

The concept of noise

Put yourself into the shoes of a sleepless victim who endure mosquitos emitting a whining sound at night. Certainly, mosquitos sound would not make you lose hearing, but you can say it is noise because of the headache, hearing high-pitched noises, exhaustion, dizziness, and nausea mosquitos cause you. Noise is an unwanted sound connected with the feeling of annoyance.

What is sound? Sound is the vibration transformation into a sound wave through a medium of gaseous, liquid, or solid elastic. The sound wave variation determines whether humans can hear about the sound. Human ears can detect variations at least 20 times a second, but not more frequent than 20000 times a second (20Hz-20kHz). And, this is Hertz.

What is a decibel? dB is a ratio between received and transmitted signal strength on a log scale. 1dB is the slightest variation that human ears can detect. 3dB differences are equivalent to the double of the sound level. The sound level humans receive comprises the sound reflected from the wall and the amount of sound being transmitted into adjacent rooms.

Human ears would not receive the complete sound level emitting from the objects. A certain level would be lost in transmission. Sound power level is the acoustic energy emitted from the source. Another concept is Sound pressure level, which measures what humans hear—the sound pressure level results from the sound energy ejected from the source transmitting to a received location. Sound power is the cause, and sound pressure is the effect.

What happens if we have more than one noise source in the room? Is the result the sum of the individual sound pressures? No, it is not the sum of the particular sound pressures.

What you should do is measure the sound pressure level of each object and calculate the difference. Look at the graph below, find the dB point on the horizontal axis, and find the value on the vertical axis according to the intersection. Add the value onto the most vociferous object. Another method is to calculate the total sound power with an equation.

Now, you have an idea what sound and noise are about. How do we practically and scientifically study noise in our environment?

Sustainable workforce

If you want your business to sustain, you will look for future trends for opportunities. If you’re going to have a well-prepared workforce, you will have to seek them out, teach and offer them career opportunities. Here are recommendations on what you can do to retain talents.

Students are one of the valuable community resources. They are well-educated with essential knowledge and skills. What they lack is real-world industry knowledge. Engage students in your community awareness program as a passage between study and work, help them understand what your industry can do for the community to pave the way for their post-secondary education.

Careers change along with the world and business trends. Offer internship to the university students in a different part of your operations and gain experiences in various cultures.

You may recruit talents through the internship program.

Retaining talents requires career advancement, providing them with the supervisory path from the technical direction. Keep them up-to-date with the information of prevailing industry trends, networks, and technology.

Design and conduct detailed benchmarks for salary review. Support the older technicians free from workplace causality by exempting them work from height.

Introduce digitalisation to perform repetitive work to reduce workload. Organise apprentices programs along with vocational training to increase the training efficiency.

By maintaining social capital and human capital in your corporate vision and strategy, community involvement will benefit your corporate in the meaningful long-run when going after the targets.

The new Acoustic Calibration Centre (ACC), now accredited by HOKLAS for calibration services

The new Acoustic Calibration Centre (ACC) has been recently accredited in Hong Kong in 2021. 

HOKLAS Accreditation

ACC is now accredited by Hong Kong Accreditation Service (HKAS) under the Hong Kong Laboratory Accreditation Scheme (HOKLAS), which has been mutually recognised by 53 laboratory accreditation bodies (58 accreditation schemes) in 45 economies.

Photo above: Why do you need third-party calibration?

Track Records

Since 2000, ACC has completed more than three hundred calibrations. The most remarkable track record is that ACC has been appointed to design the sound-level meter calibration laboratory for the Environmental Protection Department of HKSAR in consecutive years. 

The State-of-art Calibration System

ACC equips with the state-of-art calibration system – Norsonic NOR1504A – from one of the world’s leading specialist acoustic instrumentation manufacturers. The system assures all the relevant standards to comply with during the testing. The accuracy of our testing and measuring equipment (Norsonic NOR1504A) is regularly tested by the Standard and Calibration Laboratory of HKSAR. The measurement unit of Norsonic NOR1504A is traceable to the International System of Units (SI), stringent and accepted universally. Our acoustic professionals run the test with the standards-complied calibration system to identify any instrument deficiency.

COP26 illustrates ESG infiltrating to different sectors and functional units

In 2021, we have advancement in incorporating ESG – Environmental, Social, and Governance – with the working function sector.

The COP26 UN Climate Summit, the negotiations calling to “keep 1.5C alive”, achieves International Standard For Sustainability.

According to the GOV.UK, COP26’s effort attaining sustainable event had reached the ISO20121 international standard. The ISO20121 certificate awards the organisation that sets out the requirements to establish, maintain, and continually improve an event sustainability management system.

COP26 President Alok Sharma told:
“Sustainability was at the core of COP26, and I am proud that the UK has added yet another impressive standard of environmental compliance to the event with the ISO2021 certification. To build on our work with ISO20121, COP26 will also be a carbon-neutral event and become the first COP to have achieved PAS2060 validation on carbon neutrality. This will make good on our priority to reduce and avoid emissions at the highest level.”

How did COP26 demonstrate that they minimise potential adverse environmental impacts on communities and the local economy and maximise the positive effects?

The green event measures taken at COP26 are(extracted at https://www.gov.uk/government/news/cop26-achieves-international-standard-for-sustainability):

1) Prioritising low carbon alternative energy sources such as electric and low emission vehicles, solar energy for temporary traffic lights and Hydrotreated Vegetable Oil (HVO) in generators instead of diesel.
2) Prioritising sustainability by including explicit requirements in our supplier procurements and with partners.
3) Encouraging delegates to use active travel such as walking and cycling or public transport where possible.
4) Catering prioritises locally sourced, healthy, and in-season food items to minimise mileage for transportation and support local business.
5) Working with our hygiene partners, we supplied PPE that was sustainable, washable, and included filters to follow local COVID regulations and deliver a safe COP26.
6) Repurposing the furniture, which Ikea UK provided to furnish the conference, will involve working closely with Glasgow City Council to ensure the furniture is given a second life at charity organisations and local community projects across the city. Other legacy examples include distributing the conference carpets in the temporary structures to low-income families, sending MDF sheets and cotton roof panels from the Hydro installations to wood recycling and men’s shed projects in the city and turning the hundreds of metres of black-backed fabric graphics into bags, pencil cases, laptop bags, and boxes.
7) Employing local people for specific event roles.
8) Prioritising leaving a legacy in the events industry by hosting industry-wide workshops on improving standards and best practice for future events.

Leaving a positive legacy is one of the COP26 seven Sustainability Governing Principles. Practising the green event reflects the organisation culture with real action. Imagine (or you have probably seen it) you seeing the claimed green event with plastic bottle water provided for the event guests. Unquestionably, you would doubt how “green” the organisational culture is at the first glimpse.

It is also seen in real-world cases – the 2015 VW diesel emission scandal, the 2018 Starbucks’ “nitro lid” containing more plastic material than the previous lid and straw combined, and deceptive labelling and labour practices cases in the cocoa and chocolate industry. Caroline Sapriel, the founder of the global consultancy, once said: “A number of high profile cases related to false sustainability claims calls into question whether organisations are making genuine commitments.” It is always the matter of the cultural root of the governance towards sustainability.

What is TCFD (the Task Force on Climate-Related Financial Disclosures)?

It was thought that climate change had nothing to do with business. To think about it in the long term, do you dare?

Photo above: Task Force on Climate-related Financial Disclosures (https://www.fsb-tcfd.org)

Let’s talk about it. You are running a business. In a disaster triggered by climate change, your staff may not be able to go to work for alarming weather warnings. A storm may ruin your office building. The climate event is disruptive enough to cease the productivity.

There is a will; there’s a way. Before acting, stop and think about what you need. Do you have a figure about how likely your business will be impacted? What about the model for your future investment in the climate change era, which seems unlikely to get well soon? We are almost getting there – what you need is the climate-related financial numbers for your decision making.

The Financial Stability Board has created the TCFD (the Task Force on Climate-Related Financial Disclosures) to support the idea of transparency in climate-related financial reporting. Numbers of recommendations are extracted here from the TCFD report for you to realise the objectives and guidelines.

First, Governance – to disclose the organization’s governance around climate-related risks and opportunities.

Secondly, Strategy – to disclose the actual and potential impacts of climate-related risks and opportunities on the organization’s businesses, strategy, and financial planning where such information is material.

Risk management – to disclose how the organization identifies, assesses, and manages climate-related risks.

Metrics and targets – to disclose the metrics and targets used to assess and manage relevant climate-related risks and opportunities where such information is material.

The four core elements of recommendations are based on the principles for effective disclosure.

Principles for effective disclosures: 1) represent relevant information, 2) be specific and complete, 3) be clear, balanced, and understandable, 4) be consistent over time, 5) be comparable among companies within a sector industry or a portfolio, 6) be reliable, verifiable, and objective, and 7) be provided on a timely basis

It may be hard for you to imagine what will happen to your business in a catastrophe. Scenario analysis is recommended for you to consider the future impact.

As suggested by TCFD, the scenario analysis may not give you an accurate impact result; it still leads you to think about your business’s worst-case. Sustainable development is all about the environment and human development, what makes your business to be sustainable.

The TFCD recommendations are boundlessly applicable across various industries and countries. It is time to think forward and act on it.

How to capitalise on GIS’s capabilities to enhance ecological protection practice, enforcement and stakeholder engagement

The photo above: ANewR Consulting Limited is a member of ESRI Partner Network (https://www.esri.com/partners/anewr-consulting-ltd-a2T5x000008DjMVEA0)

We are happy to be a member of the ESRI Partner Network. As a reputable geographic information system (GIS) technology provider, ESRI has participated in worldwide climate crisis projects by providing a GIS application.

ANewR, as an environmental consultant, has capitalised on GIS’s capabilities in visualisation, mapping, and assessment projects, aiming to enhance ecological protection practice, enforcement and stakeholder engagement.

That’s the way how we apply GIS:

  1. Tree mapping – to manage the tree record for preservation, conservation, and maintenance purpose
  2. 3-dimensional Environmental Impact Assessment (3D EIA) – to visualise the technical, environmental assessment result
  3. Environmental Monitoring and Audit (EM&A) – to manage the project scope within the project area
  4. Construction Noise Permit (CNP) application – to facilitate e-governance and stakeholder application
  5. Cave automatic virtual environment (CAVE) – to visualise and immerse the project scene 
  6. Noise map – to visualise the road noise model of an assessment to facilitate stakeholder inquiry

All of the above GIS track records are about data sharing. Why do we share? We share for public access, customer access and internal team access. Information accessibility is sometimes required for the project. Organisations that employ data sharing solutions could often gain a competitive advantage through a more reliable operation and maintenance.

In environmental terms, the practical usage of GIS in a project to share the GIS map showing the project location associated with any potential impacts. Project is an umbrella consisting of various subsidiaries for implementation. An environmental assessment would include an ecological study that the project proponent and subcontractors would collect additional data to complete the task. Often, the project is on a long-term basis. In this case, two-way collaboration is necessary, and mutual trust must be built by connecting parties through a single organisation. GIS here would support top-level business connections and outline the collaborative workflow.

The project, especially the infrastructure project, is complex in the organisation involving different parties of diverse backgrounds. A user-friendly platform – no coding or scripting – is essential for communications and collaboration. The simplicity creates a good hub for every project proponent to work on transparency without myth. The simple collaborative platform aids the project proponents in realising the collaboration capabilities. Every project proponent could plan with clear goals identification. The project architecture is therefore designed and drawn out. It becomes easier to test the collaboration and periodically revisit the goals and architecture. And, these are what the GIS platform could offer.

Bear in mind that information loss is another significant matter causing the mismanagement of a project. Project proponents could lose data and information through the whole infrastructure life cycle, from planning, data collection, analysis, design, construct, as-built, to operate. The GIS is critical to ensure smooth processing. Below are examples suggested by ESRI of how to incorporate GIS into daily operations.
