Boundary Noise monitoring, also known as Environmental Noise monitoring can be defined as any unwanted sound and it embraces noise from industrial sources, transportation as well as from domestic premises. Environmental noise pollution can cause public annoyance and hearing impairment may result from high noise levels.
In the context of “The Planning Guidelines for Environmental Noise Limits and Control” published by Department of Environment, noise disturbance shall mean any sound which:
- Endangers or injures the safety or health of human or animals; or
- Annoys or disturbs a reasonable person of normal sensitivities; or
- Endangers or intrudes onto personal or real property boundary; or
- Exceeds the existing ambient equivalent A-weighted sound level (LAeq) by 10 dBA during the day time, and/or 5 dBA during the night time; or
- Exceeds the sound level limits as prescribed herein in these Guidelines.
Measurements of noise levels are often necessary for any of the following purposes:
- Assessing the existing noise climate
- Assessing compliance to noise limits for noise source(s) and/or project development
- Assessing environmental impact and potential community response
Allied Chemists offers accurate boundary noise levels measurement services at carefully selected locations to help our clients:
- Assess the noise levels of a particular site or region in accordance with the Planning Guidelines for Environmental Noise Limits for planning purposes and EIA study
- Assess the noise levels around an industrial site as a requirement of an ISO 14001 Environmental Management System
- Identify offending sound frequencies and to measure the sound levels of a specific noise source or a combination of noise sources for noise abatement purposes
