Vale S.A., a leading Brazilian mining company, has implemented Envirosuite's advanced noise management system to address mining noise issues and enhance community relations. This case study demonstrates how the Envirosuite system effectively manages noise issues, reduces community complaints, and streamlines the demands on monitoring staff, highlighting Vale's commitment to sustainability and social responsibility. 

To meet its obligations and minimise noise impact on nearby communities, Vale implemented a comprehensive monitoring system to track sound levels 24/7. The system had to differentiate between industrial and environmental noise, facilitate data post-processing, and adhere to strict ABNT and IEC standards.  

Vale emphasised transparency and public awareness, aiming to reduce complaints by sharing real-time acoustic and meteorological data. The system needed to be flexible, reliable, and capable of proving compliance with legal and technical standards. Alexandre Coutinho highlighted the importance of real-time alerts and data accessibility to the public as part of their commitment to environmental responsibility.  

Envirosuite's noise monitoring system assists Vale in balancing its operations with community impact by providing accurate 24/7 noise data through a web-based service. This comprehensive solution includes everything needed for effective noise management: instrumentation, installation, operation, data capture, records management, and calibration, supported by a managed support service ensuring minimal downtime. The system enables Vale to demonstrate regulatory compliance, share data transparently, and receive alerts to prevent noise breaches, with audio recordings identifying noise sources accurately.  

Initially, Vale subscribed to Envirosuite using 11 noise monitoring terminals, expanding to 33 terminals across mines and nearby communities. The system's flexibility and ease of expansion accommodate increased monitoring needs. Based on Envirosuite’s 2250 sound level meter, the software allows comprehensive analysis of noise events and integrates meteorological data. By delivering reliable, online-monitorable data, Envirosuite supports Vale's credibility, aligns public perception with actual impacts, and reduces complaints that could lead to investigations or operational constraints. 

Envirosuite provides Vale with real-time sound pressure data from mines, helping staff analyse and compare noise levels between industrial sites and nearby communities. By correlating weather conditions with recorded audio, Vale identifies noise sources and uses noise charts to understand and address complaints effectively. This technology saves time by automating reports and provides crucial data for informed decision-making, reducing noise impact and monitoring costs.  

Envirosuite's technical capabilities meet Vale's standards, enabling staff to take on more responsibilities, offer detailed information, and ensure transparency with the community. Customisable reports aid in regulatory compliance across various levels. By sharing noise data, Vale engages in fact-based discussions to mitigate noise pollution and its impact, using Envirosuite to link noise results with their operations.
