Traffic noise is one of the biggest complaints for the inhabitants of urban areas. Multitudes of people have to live with constant noise in their own homes. Of the many sources of noise, traffic causes more noise disturbance than any other source. Traffic noise effects, among other things, the ability to work, study, rest and sleep. Substantial traffic noise, if prolonged, can have serious health effects.
To protect against excessive noise from traffic, either walls or barriers can be raised along roads, or the sound insulation of buildings can be increased. Further, decreased traffic speed or the repositioning of roads can have considerable effect on traffic noise.
Conducting a noise assessment forms the basis for analyzing noise problems and decision making on proper measures needed. Traffic noise and road noise assessments are carried out with the aid of computer model simulations based on available and/or measured data. A noise assessment can be conducted by itself or can be a part of a complete environmental assessment.
Mannvit Engineering employs specialists with extensive experience in conducting noise assessments and designing noise reduction, noise control or prevention measures. In addition to this experience, company facilities for measuring and simulating acoustics are state-of-the-art, a combination that enables Mannvit to engineer effective acoustic solutions for a wide variety of applications.
