888-213-4711Gas Turbine Sound Control
eNoise Control has worked with many electric utility companies and AI data centers to help provide sound readings and noise mitigation steps for their gas turbine systems. Most of these applications are property line issues (i.e. complaints from neighbors). Typically, the gas turbine exhaust is the leading culprit. Its high velocity, high temperature flow with strong broadband and low frequency components and sometimes dominant tones can create annoyance noise and create complaints.
eNoise can help your utility company or data center navigate the baseline sound readings. We can compare those to an existing noise ordinance or determine if a noise ordinance is applicable. Most ordinances are controlled by local or state environmental noise regulations that set maximum allowable sound levels (often in dBA Leq) measured at or within the neighboring property, especially at residences. Typical planning targets for a gas turbine project near residential receivers fall roughly in the 40–55 dBA range at the property line at night, with higher limits (often 55–70 dBA or more) where adjacent land is commercial or industrial, but the exact limits depend on the jurisdiction and zoning.
Example of gas turbine intake silencers and exhaust stack silencer system
We would review three main noise sources for the turbine which would include:
- Intake Silencing: multi‑stage intake silencers and lined ductwork to attenuate compressor noise while maintaining low pressure drop and protecting against foreign object debris.
- Exhaust Silencers or Stack Silencers: high‑temperature, low‑frequency silencers with splitter baffles or reactive elements designed for the turbine’s exhaust flow and thermal cycling.
- Acoustic Enclosures: modular steel enclosures with internal acoustic lining around the turbine, generator, and auxiliaries, often including acoustic doors, louvers, and ventilation silencers.
Many AI Data Centers are using natural gas turbines as a source for its electricity needs. This can also create intake and exhaust noise problems. We offer different stack silencer options tuned to your specific frequency. This can be determined by hiring eNoise Control of an on-site sound study. We use a third octave band type 1 sound level meter to measure the turbine noise up close and at the property line. This will help ensure a successful noise mitigation strategy and help meet your acoustic goals.
