Environmental Noise Assessment Case Study
Our environmental noise assessment study was carried out in two different parts and this is an ongoing process. We undertake a concise study of the area followed by a noise monitoring measurement of the existing ambient noise levels and background levels study at the site. We also study the existing noise sources, which can generate noise problem or we can predict the noise problem using calculation according to the most relevant International Standard. Finally we evaluate the actual or predicted value against the most relevant criteria, as well we assess whether complaints from local resident are likely to occur. The most relevant criteria in the majority of the cases that we have study are the WHO (World Health Organization) Guidelines for Community Noise, Noise Exposure Categories from PPG 24 (Planning Policy Guidance: Planning and Noise or specific guidelines from different local authorities.
General trend environmental noise concerns noise from road, rail, air traffic and industry. We would include the noise from neighborhood; for instance if a Bar or Pub with an open smoking area is producing noise that affect your house or flats, such as music been played at a very high levels. We are highly qualified environmental noise experts who can provide a complete service for your business, and household to monitor and manage any environmental noise impact.

Sound Solution Acoustic Consultancy Ltd can offer advice and professional support on all aspects of monitoring, evaluation of noise results with professional noise monitoring instrument and managing your noise problem by offering to you different noise mitigation alternatives.
We are able to produce a complete study, monitoring your environmental problem and as well elaborating a "strategic noise maps" according to the EU (European Union) directive using the noise indicators Lden (day-evening-night equivalent level) and Lnight (night equivalent level). These maps can be used to assess the number of people that are affected and who's sleep has been disturbed, by your business and to offer specific noise mitigation advice to mitigate the noise impact in the area.
