What You Need to Know About Noise Maps

We experience noise on a constant basis. In fact, it is extremely rare to feel complete silence. We are constantly exposed to a barrage of sounds coming from various sources, to the point where we often don’t even register them anymore. They blend into the background, becoming part of our everyday noise. Even the once bothersome and disruptive noises can fade into the background if we make an effort to ignore them.

However, there are instances when noise and the accompanying vibrations can have detrimental effects on our well-being, both physically and mentally. To address this concern, noise emissions are carefully monitored and regulated, and one effective method used for this purpose is noise mapping. So what is noise mapping and what should you know about it?

A noise map is a visual depiction of the noise levels within a specific area. It utilizes a contour map that is superimposed onto a surveyed map of the area, highlighting different noise sources and their corresponding sound levels. The contours on the map are typically colour-coded to represent the intensity of the noise, distinguish between high and low frequencies, and indicate the distance over which the noise travels.

This provides a convenient and efficient method to visually identify the locations of noise sources and assess their impact on different receptors. They enable the evaluation of noise control measures, such as screens, fences, bunds, and alternative site layouts.

Unfortunately, noise mapping is a complex process due to the ever-changing nature of many environments. Obtaining accurate and reliable sound readings can be challenging, particularly in dynamic settings where noise sources are intermittent, unpredictable, and diverse. To create a comprehensive noise map, it is crucial to account for all these factors. This involves taking multiple measurements at different times, employing noise prediction techniques, and utilizing specialized software to gather the necessary data for generating an accurate representation of noise levels in the area.

What is the Importance of a Noise Map?

Noise maps are important for many construction and renovation projects, especially in this modern era. They are particularly crucial for local authorities when approving new motorways, railways, airports, or buildings in populated areas.

Noise maps demonstrate that developers have taken into account the noise effects of their construction activities and the surrounding environment on people inside the building once it’s completed. These maps also show that plans have been made to prevent any harm caused by excessive noise.

They are extremely helpful for comprehending and managing the risks associated with excessive noise, especially in buildings or industries that are more susceptible to such risks. For instance, buildings with machine rooms need noise maps to ensure that the noise and vibrations from the machinery do not harm the occupants.

When planning a new housing development near an airport, noise maps can assess the impact of air traffic on the area and help developers decide on measures to reduce noise. Similarly, in commercial or industrial projects, a noise map can predict the noise generated by activities and equipment like AC units, and assess their impact on nearby noise-sensitive areas. They are also used to test and evaluate the effectiveness of noise control measures.

How is a Noise Map Made?

Noise mapping is achieved by gathering measurements from different locations in and around a planned or existing development site. This is done using specialized equipment, and it is preferable to conduct the measurements over extended periods to gather comprehensive data. The selection of measurement points is crucial to ensure complete coverage of the area under consideration, and adjustments can be made if necessary during the measurement period.
