DOOR NOISE
Mechanical equipment rooms are essential for building operations, housing pumps, compressors, boilers, and large HVAC air handlers. While these systems are often enclosed behind mechanical room walls, the access door frequently becomes a weak point for sound transmission. In many commercial buildings, sound levels inside mechanical rooms can reach 80–90 dB(A), especially when multiple pumps or compressors operate simultaneously. Without proper noise control, that sound easily escapes through the door and spreads into nearby hallways and offices.
This noise leakage can become a daily distraction for employees working near the mechanical area. Office staff may experience difficulty concentrating on tasks or holding conversations when low-frequency mechanical noise constantly leaks into the workspace. Over time, persistent background noise above 60–65 dB(A) can reduce productivity and increase fatigue, particularly in quiet office environments designed for focused work.
Standard doors provide minimal sound isolation because they lack the mass and acoustic sealing required to block airborne sound. Even when walls contain insulation, the door opening often acts like an acoustic leak. Sound waves pass through the door panel and gaps around the frame, allowing mechanical noise to escape into surrounding work areas.
The ImpactaCore® Acoustic Door Blanket System offers a practical solution by installing directly over the mechanical room door opening. This high-performance acoustic door blanket combines mass-loaded vinyl barriers with sound-absorbing quilted fiberglass layers to significantly reduce sound transmission through doorways.
By covering the door opening with a commercial acoustic door barrier, facilities can often reduce noise levels from 85 dB(A) down to approximately 55–60 dB(A) in adjacent spaces. This improvement creates a healthier work environment while maintaining easy access to mechanical equipment when maintenance is required.
