Noise reduction in the industry with noise maps – Part 1

Introduction

Nowadays society is strongly sensitive to environmental issues and sustainability. DECO estimates that in Portugal there are about of 800.000 people exposed to excessive noise and complaints concerning this, are the most common complaint with respect to the environment. The noise emission and the right not to occur to disturb are regulated and people are informed of their rights. So the need to reduce the noise to acceptable values is an important priority for many companies. These noise reduction actions are often concerned significant investments, and we must ensure the success of the project and minimizing their costs, and this is a major concern of those responsible for the environment. Give the importance of objective approach exists as regards the assessment of the impacts of investments to make.

Case Study Industrial Noise Reduction Plan

Employees of dBwave.i have extensive experience in this area where they began to act in 2002.

The most effective tool to identify noise problems of industrial companies, given the quantity and diversity of equipment normally concerned, is the development of noise control action plans involving the realization of noise maps.

From 2002 that employees of dBwave developed intense work of preparation of noise maps of industrial facilities and action plans among which are:

ENEOP2 – Wind Farm Operation, S.A.Cimpor, S.A. (CP Souselas, Alhandra and Loulé)
Supreme Cement Factory in AdrianopleSecil, S.A. (Factories Maceira, Pataias, Outão)
EEM – EMP. WOOD ELECTRICITY, S.A.Thermoelectric Born from Central
Factories Linxe (France), Knowsley (UK), Mangualde (Portugal)- Sonae Indústria, S.A.Thermoelectric Bachaquero Central, Venezuela
Cements Mills (Spain – Barcelona)Thermoelectric Tamare Central, Venezuela
Cemex Cement (Spain - Palma Maillorca)

 

International experience:

  • Portugal
  • Brazil
  • Angola
  • UK
  • France
  • Spain
  • Venezuela

Case Study Noise maps of industrial plants

Employees of dBwave.i have extensive experience in this area where they began to act in 2005.

In,pt 2007 Portugal implemented legislation that made it mandatory to carry out noise mapping for, entre outros, industrial developments. Since then the employees of dBwave developed intense work of preparation of noise maps of industrial plants including meet:
