Courthouses are typically large, high-ceilinged spaces with hard reflective surfaces: marble floors, plaster walls, wood paneling, glass gallery dividers. These materials are durable and authoritative - and acoustically brutal. Speech intelligibility scores in untreated courtrooms routinely fall below acceptable thresholds, making it harder for jurors, attorneys, and court reporters to follow proceedings accurately.
Police stations present a different but equally serious problem. Holding areas echo badly, making communication difficult and creating elevated stress for both officers and detainees. Interrogation rooms - where the content of conversation is legally sensitive - often have speech privacy ratings so low that adjacent rooms can follow the dialogue. This is not a minor issue; it has evidentiary implications.
Acoustic Sound Panels' treatment solutions for judicial and law enforcement environments are designed around performance, durability, and compliance. Our Homasote Sound Barrier Panels (DesignWall 550/440, STC-50 rated) address sound transmission between spaces - critical for interrogation room privacy and administrative offices. Standard fabric-wrapped panels reduce reflections and improve speech clarity in courtrooms, hearing rooms, and multipurpose meeting spaces. Class A fire-rated materials are available across our product line to meet institutional code requirements.
Whether you're retrofitting an existing courthouse, outfitting a new police precinct, or treating a juvenile detention facility, we'll assess your specific rooms and recommend the right combination of absorption and isolation products. Our free room analysis gives you a written treatment plan with product quantities and placement recommendations - no guesswork, no overselling.

Frequently Asked Questions
What NRC rating do acoustic panels need to meet for courtroom intelligibility?
For courtrooms and hearing rooms, panels with an NRC of 0.85 or higher are typically recommended. Our standard fabric-wrapped panels achieve NRC ratings of 0.85–1.00 depending on thickness (2" or 4") and core material. For most courtrooms, 2" panels on the rear and side walls combined with ceiling treatment will achieve acceptable speech intelligibility scores.
How do you achieve speech privacy in interrogation rooms?
True speech privacy requires addressing sound transmission, not just absorption. Our Homasote DesignWall STC-50 panels are designed for this - they're a sound barrier system, not just an absorber. Installed correctly, they significantly reduce the sound transmission class of a wall. For complete isolation, combining barrier panels with door seals and addressing HVAC penetrations gives you the most reliable result. We can help you assess what combination makes sense for your specific layout.
Are your acoustic panels Class A fire rated for use in government buildings?
Yes. Our panels are available in Class A fire-rated configurations using Burch Fabrics Prime Time fabric - a widely specified fabric in institutional settings. Class A (ASTM E84, Flame Spread Index ≤ 25) is the highest fire rating for interior finishes and meets the requirements for most government facilities. We'll confirm the appropriate specification for your project when we review your room.
Can acoustic panels be installed in holding areas and detention spaces?
Yes, though material selection matters. For holding areas, we recommend panels with durable, cleanable fabric facings and secure mounting systems (Z-clips or flush mount) that prevent tampering. Our panels use commercial-grade materials rated for institutional use. Contact us to discuss the specific requirements for your facility's security and maintenance needs.
What is the typical installation process for a courthouse acoustic treatment project?
Most judicial facility projects begin with a room analysis to determine placement, quantity, and product type. Our panels arrive ready to mount - no specialized tools required. Z-clip mounting is the standard method, which allows panels to be removed for maintenance or repositioning. We provide complete mounting hardware. Lead times are typically 2–3 weeks for standard panels, with Class A fire-rated materials available on the same schedule.
Can you match government fabric specifications like Burch Fabrics Prime Time?
Yes. We build our panels with Burch Fabrics Prime Time fabric as a standard Class A option, along with other GoM fabric lines. FR701 is an industry-standard specification fabric that appears on GSA schedules and is recognized in many institutional acoustic specifications. We can also accommodate other approved fabric specs - contact us for custom material matching.
