Dedicated low-frequency acoustic isolation enclosures for compressor and pump rooms — isolating 24/7 continuous baseline noise sources. NRC 0.50–0.80 walls reduce facility-wide ambient noise by 5–12 dBA, lowering cumulative OSHA 1910.95 8-hour TWA exposure for all workers and reducing hearing protection program scope.

Compressors and pumps run continuously, establishing the facility's baseline acoustic environment. All other operations' noise levels are additive to this baseline. OSHA 1910.95 measures the 8-hour TWA for all workers. Reducing baseline noise proportionally reduces every worker's cumulative exposure, potentially eliminating the need for facility-wide hearing protection programs.
Isolating baseline noise reduces 8-hour TWA for all employees. If baseline drops from 82 to 75 dBA, all workers' cumulative exposure decreases, potentially shifting them below 85 dBA threshold and eliminating hearing protection program enrollment.
Compressors emit 100–500 Hz predominant frequencies. Modular Solutions specifies materials optimized for low-frequency absorption — not high-frequency acoustics, which would be misdirected for this application.
Enclosures designed for uninterrupted compressor/pump operation — no thermal issues, adequate ventilation for continuous cooling, and structural support for equipment vibration isolation integration.
Modular panel design allows maintenance (oil changes, filter replacement) without removing acoustic barriers. Enclosure remains intact and effective between service events.
Compressor vibration transfer to structure is minimized through isolation mounts. Acoustic enclosure structure accounts for vibration forces — preventing acoustic barrier transmission of vibration noise to adjacent structures.
Baseline noise reduction is often more cost-effective than facility-wide hearing protection program administration. Isolating source eliminates PPE program, training, and medical surveillance requirements for potentially hundreds of workers.
Typical performance data for compressor room isolation:
Continuous baseline noise is the ambient sound level generated 24/7 by infrastructure (compressors, pumps, HVAC, motors). OSHA 1910.95 measures noise exposure as 8-hour TWA (time-weighted average). High baseline noise increases all workers' cumulative exposure, lowering the threshold at which hearing protection becomes mandatory. Isolating baseline noise sources reduces facility-wide TWA, potentially reducing hearing protection program scope to specific high-noise areas only.
Reciprocating compressors emit predominantly low-frequency noise (100–500 Hz) from piston impacts and pressure pulsations. Rotary screw compressors emit mid-frequency noise (500–2000 Hz). Modular Solutions addresses operation-specific frequency profiles with acoustic materials targeting the dominant compressor type in your facility.
Yes. If compressor isolation reduces facility baseline from 82 dBA to 75 dBA, the 8-hour TWA for other workers decreases proportionally. This can shift some workers from 85+ dBA exposure (requiring hearing protection program) to <85 dBA (no program required). Engineering documentation quantifying baseline reduction supports this compliance strategy.
No. Modular enclosures include removable panels and hinged access sections at service points — oil changes, filter replacement, and other maintenance occurs without disassembly. Acoustic performance maintained between maintenance events.
Compressor cooling requires intake and exhaust airflow. Modular enclosures include ventilation passages with acoustic baffles — air inlet/outlet noise is absorbed as air moves through the barrier. Cooling performance remains adequate for continuous operation.
Isolate compressors and pumps to reduce cumulative worker exposure and potentially eliminate hearing protection program requirements.
