Acoustic Solutions for Data Centers
THE CHALLENGE
DATA CENTER NOISE SOURCES
Data centers built without acoustic planning face permit denials, costly retrofits, community lawsuits, and worker health liability.
85-95 dB(A)
CONTINUOUS
Closed-loop cooling systems
High-speed fans operate 24/7 across all data halls, projecting noise horizontally toward adjacent properties day and night.
90-105 dB(A)
WEEKLY TESTING
Backup Power Generators
Diesel gensets required for redundancy at every campus. Generator noise is the #1 community complaint at data center approvals nationwide.
70-85 dB(A)
ROOFTOP
Cooling Tower & AHU Exhaust
Air handling units and cooling tower fans direct broadband noise horizontally toward surrounding agricultural and residential properties.
55-80 dB(A)
LOW FREQUENCY
Transformer & Electrical hum
Low-frequency tonal hum from power transformers. Most state codes add a −10 dB correction for prominent tones, making limits significantly stricter.
The Solution
Complete Exterior + Interior Acoustic System
A dual-system approach that controls noise at the perimeter and inside the facility — meeting every applicable standard.
NOISE PLANNING CAN’T BE AN AFTERTHOUGHT
Remote Today — Not Tomorrow
Background noise at remote sites is 30–40 dBA at night. Any facility noise triggers strict limits immediately
Neighbors Always Arrive
Development follows major investment. Low-frequency cooling drone is the #1 community complaint at approval hearings.
Tonal Correction Penalty
Data center fans produce prominent tones. Most US state codes apply an additional −10 dB correction at tonal frequencies.
Always Under Nighttime Limits
Data centers never shut down. The most stringent nighttime limits apply continuously — 365 days a year.
Data Center Perimeter Acoustics · The Leadership Standard
The Low-End HUM Requires High-End Acoustics.
The Problem
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.
The Liability · The Solution
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 — STC 53 / NRC 0.85, Riverbank Labs certified, proven since 1993.
REGULATORY COMPLIANCE
Troy System vs. Key US Noise Standards
Every US data center is subject to a layered set of federal, state, and local noise standards — applied from the day it opens.
| Standard | Requirement | Troy Performance | Result |
|---|---|---|---|
| FHWA NAC Category B | 67 dB(A) Leq — residential receptors | STC 50 · NRC 0.85 · 50 dB TL + absorption | Exceeds |
| HUD 24 CFR Part 51 | 45 dB(A) interior · 65 dB(A) exterior | STC 50 exterior · CAC 38 + NRC 1.0 interior | Exceeds |
| EPA Community Noise | 55 dB(A) day · 45 dB(A) night (outdoor) | STC 50 blocks 20–35 dB beyond limits | Exceeds |
| OSHA 29 CFR 1910.95 | 85 dB(A) TWA · 8-hr action level | CAC 38 · NRC 1.0 — cuts server hall reverb | Exceeds |
| State Property-Line Codes (All 50 States) | 45–80 dB by octave band · Class B receiving land | Troy TL: 38–66 dB/band · NRC 0.85 absorption | Exceeds All Bands |
| Local Zoning / CUP | Typically 50–65 dB(A) at property boundary | 10–30 dB additional margin above limits | Full Margin |
Why the Troy Solution Matters — Before the First Slab Is Poured
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 0.85, 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.
Certified Performance Across the Frequency Spectrum
NVLAP-Accredited Riverbank Acoustical Laboratories · Tests RAL-A11-208a (NRC) & TL26-262 (STC)
NRC 0.85 — Sound Absorption by Frequency
STC 53 — Sound Transmission Loss by Frequency
Quiet Is a Liability Question.
Communities sue. Regulators fine. Property values fall. Walls of Troy panels absorb the HUM at the property line — before it ever reaches a neighbor.
Rethinking Structural Panels from the Ground Up
See the Innovation
Most structural wall systems use the same basic formula: foam sandwiched between sheeting. Walls of Troy takes a completely different approach. Our panels are built from wood fibers mixed with Portland cement—a homogeneous material that combines structural strength with exceptional acoustic performance, energy efficiency, and durability. The science is elegant:
Watch Bill explain how this structural innovation changes everything.
Manufacturing Process of Wood Wool Cement Panels
The manufacturing process of wood wool fiber cement panels involves several key steps:
SUSTAINABLY SOURCED WOOD
SHREDDED INTO WOOD WOOL
COMBINED WITH PORTLAND CEMENT
MOLDED & CUT INTO PRECISE PANELS
Timber, often from pine, spruce, or fir, is prepared by cutting into lengths for processing into wood wool fibers:
The mineralized wood wool is combined with Portland Cement. The mixture is then molded, stacked, and pressed:
The panels undergo a crucial curing process, allowing them to harden and gain strength and achieve the desired mechanical properties:
