Advanced DG Acoustic Enclosure & Noise Mitigation Project
The Challenge
A commercial facility located adjacent to a luxury residential complex installed three 1010 KVA diesel generator (DG) sets for backup power. Despite using low-noise equipment and compliant silencers, operational noise levels exceeded residential acoustic limits. Late-night DG operation led to community disturbance, police complaints, and restrictions on generator usage during night hours.
The Thermosonics Approach
Thermosonics conducted a detailed acoustic assessment and identified multiple noise sources on the shared podium, including generators from other agencies. To ensure transparency and long-term compliance, coordination with consultants and the Maharashtra Pollution Control Board (MPCB) was initiated for independent noise mapping and validation.
Our Comprehensive Noise Mitigation Solution
- Design and installation of a secondary acoustic enclosure covering all DG units
- Optimization and rerouting of exhaust piping
- Integrated airborne and structural noise control measures
- Engineering focused on maintaining airflow, safety, and performance
The Result
The implemented acoustic solution successfully reduced noise levels within environmental norms for residential areas. Official noise mapping was conducted during silent hours, leading to:
- No Objection Certificate (NOC) from MPCB
- Clearance from neighbouring residential stakeholders
- Reliable night-time DG operation without further complaints
