> **Summary:** Hyperscale data centers in Navi Mumbai, Chennai, and Noida house massive diesel generator arrays and cooling towers. Learn how to engineer acoustic louvers and silencers for CPCB compliance.

India has become one of the world's fastest-growing data center hubs, with hyperscale facilities concentrating across Navi Mumbai, Chennai, Noida, and Hyderabad. To ensure 99.999% uptime, these campuses house massive multi-megawatt backup Diesel Generator (DG) arrays and high-capacity rooftop chiller plants. When emergency test runs occur, thousands of horsepower create deafening sound pressure levels (110+ dBA) that violate CPCB ambient noise standards at the plot perimeter. Here is how Boho Acoustics engineers high-performance data center noise mitigation.

## 1. Multi-Megawatt DG Set Noise Challenges

Data center backup generators require immense airflow for combustion and radiator cooling. Completely sealing the generator room is impossible due to heat dissipation requirements.

Sound escapes through radiator discharge openings, fresh air intake louvers, and engine exhaust stacks. Our engineers design heavy-gauge galvanized acoustic louvers and inline splitter silencers that allow maximum static airflow while attenuating sound by 25 dB to 35 dB.

## 2. Rooftop Chiller and Cooling Tower Acoustic Barriers

Data halls generate continuous thermal loads requiring industrial chillers operating 24/7/365. Nocturnal noise limits in surrounding areas are strictly 45 dBA to 55 dBA.

We construct modular structural acoustic perimeter sound barriers surrounding rooftop chiller farms. Panels feature perforations on the equipment-facing side with high-density absorptive mineral cores to trap radiated compressor sound.

## Frequently Asked Questions

### What is an acoustic louver in a data center?
An acoustic louver is a specialized exterior ventilation blade that allows high-volume cooling air to enter the building while interior sound-absorbing materials block machinery noise from escaping.
