ACOUSTIC CURTAIN BLANKET ENCLOSURES FOR
General Dynamics —
Outdoor
Generator Noise
Control
Overwiew
General Dynamics operates a large manufacturing and
testing facility where multiple outdoor standby generators
support critical operations. However, the generator array
produced continuous low-frequency noise that carried
beyond the property line, resulting in complaints from nearby
commercial tenants.
CHALLENGE
- Continuous low-frequency rumble from diesel generators
- Noise levels increasing at night
- Limited space prevented permanent masonry structures
- Required a fast-install solution with no equipment
downtime - Must withstand rain, UV, and seasonal temperature
changes
SOLUTION: OUTDOOR ACOUSTICAL BLANKET ENCLOSURE USING ANC- AB110EXT-R2
To address the low-frequency generator noise, we supplied a
custom outdoor acoustical blanket enclosure using ANC-AB110EXT-
R2 Sound Curtains, our high-performance composite model
designed specifically for challenging outdoor industrial
environments.
Why R2 was selected:
- Superior noise-blocking capability for low-frequency generator noise
- Weather-rated composite construction
- Reinforced UV-resistant exterior
- Compatible with modular steel framing for non-invasive
installation
The enclosure included removable access panels, ventilation
openings with acoustical baffles, and a durable attachment system engineered for long-term outdoor exposure.
RESULTS
- 13–18 dB noise reduction measured at the property line
- Completely eliminated tenant complaints
- Equipment remained fully serviceable with quick-release access points
- Avoided permitting and construction costs associated with
permanent buildings
