Environmental Noise

ENVIRONMENTAL acoustics focuses on controlling and restraining the impact of noise on the environment, caused by companies, leisure facilities, the infrastructure (rail, road and air traffic), labor (construction site) or neighbours. Companies must comply with the conditions applicable in the relevant region, as stipulated by environmental legislation, as well as other noise-related conditions. Environmental sound is generally considered noise, when it propagates to areas where it is undesired or regarded as intrusive. In our communities, unwanted noise in residential areas, schools, offices, public areas, etc. can lead to speech interference, annoyance, and interrupted sleep, any of which can generate complaints from neighbors and possible legal actions from local and regional authorities.

Measuring the total or ‘ambient’ noise at a single point is often necessary before the commencement of a development as part of an overall Noise Impact Assessment. Establishing the frequency content of a baseline traffic noise survey allows the acoustician to design the facades and glazing of sensitive buildings to keep intruding levels low. Site evaluations for source identification and characterization can be conducted as well as long term monitoring of noise and vibration in urban and industrial settings and surrounding areas. CYA can assist architects, industrial planners, and environmental experts to understand and assess the impact of noise on their projects.
