How Does Noise Mapping Work, And Why Do I Need It?

Noise surrounds us constantly, and it is a rare occurrence to encounter pure silence. Often, we find ourselves surrounded by a multitude of sounds. Frequently, we are unable to escape this auditory onslaught.

Noise can often blend into the background, becoming unnoticeable. Even the sounds that used to annoy us can be ignored if we make an effort. However, certain noises and vibrations can negatively impact our well-being, both physically and mentally. That is why noise emissions are closely regulated and monitored, primarily through the method of noise mapping. If you need to reduce the noise level in your home or office, check out the guide for sound proof insulation for stud walls.

What Does Noise Mapping Entail?

A noise map is a graphical depiction of the noise levels present in a specific location. It is a straightforward concept that provides a clear understanding of the noise distribution in an area.

Contour maps are utilized by placing them over a survey map of the area. It shows various sources of noise and their respective sound intensities. Typically, The contours are depicted using different colors, to illustrate the strength of the sound, whether it is a high or low pitch, and how far it travels.

Noise maps provide a convenient and straightforward means to identify the origins of noise and understand their impact on different receptors. Additionally, they enable the evaluation of noise mitigation measures, such as screens/fences, bunds, and alternative site arrangements.

Noise mapping is not a straightforward procedure. Due to the dynamic nature of many environments, it can be quite complex to accurately assess and depict noise levels.

On a regular basis, if not continuously, obtaining a precise and dependable measurement for sounds is crucial.

In dynamic settings with varying and unpredictable noise sources, it is crucial to include all of them when creating a noise map. This entails collecting numerous measurements at different times and utilizing noise prediction methods and specialized software to obtain the necessary data for an accurate noise map.

What Is the Importance of Having A Noise Map?

Noise maps are highly valuable in various projects, especially in contemporary construction and renovation endeavors. In fact, noise maps play a critical role in the approval process for many local authorities, specifically when it comes to new infrastructure projects like motorways, railways, and airports, as well as new construction and renovations in already established areas. These noise maps demonstrate that developers have taken into account the potential noise impact of their construction activities and the surrounding environment on individuals residing within the finalized structure. Moreover, these maps also reflect the developers’ implementation of precautionary measures to mitigate any harm caused by noise.

Noise maps can provide valuable assistance in evaluating the potential dangers posed by excessive noise levels.

Especially in structures or sectors that may have a higher vulnerability compared to others. For instance,
Buildings that house machine rooms will require noise maps in order to ensure the auditory environment is properly managed.

The objective is to ensure that the vibrations produced by the machinery do not have a negative impact on the individuals inside the building. In the event of the installation of new equipment, it is crucial to assess its effects on the occupants.

When a housing development is being planned near an airport, the use of noise maps can effectively evaluate the potential impact of air traffic on the area. These maps assist builders in making informed decisions regarding soundproofing measures. Similarly, noise maps can also be utilized in the context of commercial or industrial development to estimate the noise generated by activities, air conditioning units, and other sources. By considering existing noise-sensitive receptors and testing various noise control measures, noise maps contribute to sound management strategies.

How Can You Create a Sound Map?

Informed individuals can conduct noise mapping by collecting measurements from different locations in and around a potential or current development site. This process involves the use of specialized equipment and ideally spans over extended periods to gather ample data. The selection of measurement points is done diligently to ensure complete coverage of the area, and adjustments can be made if necessary throughout the duration of the measurements. Subsequently, all the collected data is processed by advanced software to determine the noise levels.

The variation in levels, along with reflections, screening, and transmission paths, are important aspects to consider.

However, for the majority of individuals, this entails a significant amount of additional effort, resources, and equipment that they do not possess.

Many individuals, particularly those facing time constraints, choose to enlist the services of an acoustic contractor instead of taking on the task themselves.

Consulting firms such as ours are sought out by those who possess a certain level of knowledge. We specialize in conducting noise surveys, utilizing cutting-edge equipment in order to obtain accurate and detailed results.

This tool is capable of evaluating noise and vibration levels in any given setting and generating comprehensive three-dimensional noise maps for your reference.

We offer precise demonstrations of the origins of noise and provide guidance on how to obtain it.
measures to prevent negative noise impact and the process of obtaining planning permission will be discussed, providing you with the necessary information.
