There is a great range of specialisations within the ANC. Environmental noise consultants carry out measurement, calculation, evaluation and mitigation of noise pollution to fit within current noise regulation and produce an environmental impact assessment often leading to appearance as an expert witness at public inquiries.
Brüel & Kjær supplies systems for occupational health, helmet/cabin/cockpit noise assessment, acoustic and human vibration monitoring, urban noise monitoring and noise-mapping of vehicles in order to test and monitor the environmental noise impact, and to look for ways of reducing environmental noise impact on armed forces personnel and local ...
These disturbances, while unavoidable, are managed through a series of measures aimed at minimising the impact. Dust proofing of HDB Flat undergoing HIP [23] Noise Control: To reduce the noise caused by hacking, drilling, and other construction activities, contractors use specialised equipment such as dust extractors and noise-reducing tools ...
The Environmental Impact Assessment Law (EIA Law) requires that an environmental impact assessment be completed prior to project construction. However, if a developer completely ignores this requirement and builds a project without submitting an environmental impact statement, the only penalty is that the environmental protection bureau (EPB ...
Acoustical engineers concerned with environmental acoustics face the challenge of measuring or predicting likely noise levels, determining an acceptable level for that noise, and determining how the noise can be controlled. Environmental acoustics work is usually done by acoustic consultants or those working in environmental health. [13]
An effective model for noise control is the source, path, and receiver model by Bolt and Ingard. [9] Hazardous noise can be controlled by reducing the noise output at its source, minimizing the noise as it travels along a path to the listener, and providing equipment to the listener or receiver to attenuate the noise.
An additional study examined the impact noise exposure had on the Indo-Pacific humpbacked dolphin (Sousa chinensis). The dolphins were exposed to elevated noise levels due to construction in the Pearl River Estuary in China, specifically caused by the world's largest vibration hammer—the OCTA-KONG. [61]
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
