Acoustic Partitions

Modular noise barrier systems for manufacturing, industrial, and specialized environments — STC-rated sound absorption enclosures for machinery isolation, compressor and generator rooms, welding cells, grinding areas, and pump stations. Reduce facility noise below OSHA action thresholds and eliminate hearing conservation program requirements.

Acoustic Noise Barrier Product Lines

Seven specialized acoustic barrier systems targeting high-noise industrial operations. Select your application to find the sound absorption solution matching your noise reduction targets.

Why Modular Acoustic Partitions for Industrial Noise Control

Permanent masonry or poured concrete noise barriers are inflexible and expensive to modify. Thin foam panels lack structural integrity. Modular acoustic systems deliver compliant noise reduction and reconfigurability for changing manufacturing environments.

OSHA Hearing Conservation Compliance

Facility noise at or above 85 dBA TWA triggers OSHA hearing conservation programs — baseline and annual audiograms, hearing protection, training. Acoustic enclosures reduce facility noise below action thresholds, eliminating or reducing program scope and cost.

STC-Rated Sound Absorption

Standard partitions: STC 28–35 (10–15 dB insertion loss). Enhanced enclosures: STC 40–50 (18–30 dB insertion loss). Sound Transmission Class ratings are specified and documented for your facility noise assessment and audit compliance.

Integrated Ventilation & Exhaust

Every acoustic enclosure includes dedicated exhaust connection points, plenum chambers for airflow, and silencer provisions. Equipment can maintain full operational ventilation while acoustic absorption prevents noise transmission through exhaust air.

Reconfigurable without Structural Modification

When production equipment changes, production lines reorganize, or noise sources relocate, modular acoustic systems disassemble and rebuild in new locations. Bolted connections allow full reconfiguration without facility shutdown or construction permits.

Specialized Acoustic Material Options

Melamine foam for standard noise; mineral fiber for fire-rated applications; fiberglass with facing for humid environments; mass-loaded vinyl for maximum density. Material selection matches your noise reduction target and environmental conditions.

Improved Workplace Safety & Morale

Reduced noise levels decrease operator fatigue, improve communication clarity, and reduce stress-related health impacts. Lower noise facilitates better verbal communication in operations and maintenance, reducing miscommunication hazards.

Industries & Facility Operations

Acoustic partitions protect worker hearing and improve facility environments in manufacturing, industrial, and specialized settings.

Acoustic System Specifications & Compliance Options

Acoustic partitions must be engineered to meet facility noise reduction targets and comply with OSHA requirements. These are the key specification dimensions we engineer to.

Sound Transmission Class (STC) Standard partitions: STC 25–32 (side-screen, partial). Enhanced: STC 38–45 (three-sided/partial enclosure). Full enclosures: STC 48–55+ (complete isolation). Rating selected based on noise reduction target and OSHA action threshold compliance.
Noise Reduction Coefficient (NRC) Interior absorption rating: NRC 0.7–0.95 depending on material and thickness. Higher NRC improves sound absorption within the enclosure. Selection balances absorption, fire rating, and thermal performance requirements.
Material Selection Melamine foam (NRC 0.8+, economical); mineral fiber (NRC 0.75, fire-rated); fiberglass (NRC 0.85, moisture-resistant); mass-loaded vinyl (high density, for maximum STC). Material specified based on application, environment, and compliance requirements.
Ventilation & Exhaust Integration Dedicated exhaust connection flanges; plenum chambers for airflow distribution; silencer provisions for discharge air; intake cooling/filtering options. Equipment maintains full operational airflow while acoustic enclosure prevents noise transmission.
OSHA Hearing Conservation Compliance Enclosure engineered to reduce facility noise below 85 dBA TWA action threshold. Post-installation noise assessment documents compliance and supports OSHA compliance file. Baseline and annual audiogram requirements may be eliminated or reduced based on new noise levels.
Fire & Building Code Compliance Material selection matches building code fire rating requirements (typically fire-rated materials for enclosed spaces). Ventilation provisions coordinate with facility HVAC and fire suppression systems. UL and FM certifications provided where required.
Access & Maintenance Provisions Personnel doors with panic hardware for emergency egress; removable/hinged acoustic panels for equipment maintenance access; internal work platform provisions where required for interior service.
Lead Time & Fabrication Standard noise barriers: 2–4 weeks. Custom full enclosures: 4–8 weeks. Specialized high-performance systems: 6–10 weeks from approved drawings and specification sign-off.

Frequently Asked Questions

Common questions about acoustic partition selection and industrial noise control.

How much noise reduction can acoustic partitions provide?

Sound Transmission Class (STC) ratings depend on panel design and material. Standard partitions: STC 28–35 (10–15 dB insertion loss). Enhanced: STC 38–48 (18–28 dB insertion loss). Full enclosures: STC 50+ (>30 dB). Noise reduction is engineered to meet your OSHA action threshold targets.

What's the difference between partial partitions and full enclosures?

Partial partitions screen sound from one direction but allow noise to travel around the sides (STC 25–32). Full enclosures surround the noise source completely with integrated ventilation (STC 40–50+). Enclosure type is selected based on facility layout, personnel exposure, and noise reduction targets.

How do you handle ventilation when equipment is completely enclosed?

Every acoustic enclosure includes dedicated ventilation exhaust points, plenum chambers for airflow, and silencer provisions for discharge air. Equipment exhaust is routed through acoustic attenuators before leaving the building. Intake air can be cooled or filtered as needed.

Can acoustic partitions be moved or reconfigured?

Yes. Modular bolted partitions are fully reconfigurable. Sections disassemble, anchor points are filled, and the partition rebuilds in a new location or around different equipment. This is a major advantage over permanent concrete or masonry noise barriers.

What acoustic panel materials are available?

Standard materials include melamine foam, mineral fiber, and fiberglass with various fire ratings and NRC coefficients. Mass-loaded vinyl provides maximum density for critical noise applications. Material selection balances acoustic performance, durability, temperature tolerance, and cost.

Do OSHA hearing conservation programs apply to our facility?

If equipment generates noise at or above 85 dBA TWA (time-weighted average), OSHA hearing conservation is required — baseline and annual audiograms, hearing protection, and training. Acoustic enclosures can reduce noise below action thresholds, reducing or eliminating program requirements.
