Data Center Perimeter Acoustics
The Low-End HUM Requires High-End Acoustics
Every modern data center generates a constant low-frequency drone — the relentless HUM of cooling fans, compressors, pumps, transformers, and standby generators. It travels farthest, penetrates walls, and reaches the bedrooms of the neighbors. It triggers community complaints, halts approvals, and exposes owners and operators to nuisance lawsuits and costly retrofits.
Fences and reflective walls cannot stop it. Walls of Troy can — a 22’+ tall absorptive and isolation barrier rated STC 53 / NRC 0.90, Riverbank Labs certified, and proven on American highways since 1993.
Performance at a Glance

For Contractors & Developers
Specify Troy on day one and you build a campus that passes acoustic compliance at every octave band — no costly retrofits, no permit-revision cycles, no schedule-killing change orders.

For City Councils & Planners
Approving a data center is a long-term commitment to the residents around it. Conditioning approval on Walls of Troy — STC 53, NRC 0.90, 22’+ tall — is the most defensible vote you can take.

For Homeowners & Neighbors
The reason you can hear a data center a mile away is the low-frequency HUM no ordinary wall stops. Walls of Troy absorbs and blocks that frequency band — restoring the quiet you bought your home for.
Certifications & Standards
Certified Performance Across the Frequency Spectrum
34 dB at 31.5 Hz
Transmission loss at the deepest end of the data center HUM band, where ordinary walls fail.
64 dB at 5 kHz
Transmission loss climbs to 64 dB at high frequencies. STC 53 per Riverbank Labs test RAL-TL26-262.
NRC 0.90
The absorptive face soaks up sound instead of reflecting it back toward the community. Riverbank Labs test RAL-A26-364.
UL 723 Class A
Zero (0) flame spread and zero (0) smoke developed. Absorptive panels are machined and painted for long life and no maintenance.
Applications
Where We’re Used

Exterior Perimeter Walls
22’+ absorptive and isolation walls that stop the HUM at the property line.

Chiller & Cooling Yards
Contain the 24/7 fan and compressor drone — the main low-frequency source.

Generator & Equipment Yards
Shield neighbors from backup generator test runs and transformer hum.

Interior Ceiling Systems
CAC 38 · NRC 1.0 ceiling systems for interior equipment and support spaces.

New Campus Construction
Design acoustics in before permitting to avoid denials, lawsuits, and retrofits.

Retrofits & Expansions
Bring existing campuses into compliance as noise rules tighten.
Quiet Is a Liability Question
Communities sue. Regulators fine. Property values fall. Walls of Troy absorbs the HUM at the property line — before it ever reaches a neighbor. Plan the wall before the permit hearing.
