The Seven Scenarios of Sound
Understanding the acoustic challenges in your facility is the first step to solving them. Troy Acoustics has identified seven common scenarios that affect noise levels in shooting ranges and other facilities.
Reverberation & Echo
Sound bouncing off hard surfaces creates a reverberant field that multiplies noise levels far beyond the original shot. In a concrete shooting range, a single gunshot can generate up to 165+ dB due to reflections. Troy Board absorbs these reflections, reducing reverberation time to 1.25 seconds or less.
Structure-Borne Sound Transmission
Noise traveling through walls, floors, and ceilings into adjacent spaces. Standard drywall provides minimal isolation. Troy Board’s 72 STC rating stops structure-borne sound — the highest rating of any acoustic product in the industry.
Flanking Paths
Sound finding its way through gaps, seams, electrical outlets, HVAC ducts, and other openings around acoustic barriers. Troy’s site-specific design process identifies and seals all flanking paths to ensure maximum acoustic isolation.
Impact Noise
Vibration and impact noise from muzzle blast, foot traffic, or mechanical equipment traveling through structural elements. Troy Wool provides dense, resilient backing that absorbs impact energy before it can radiate as airborne sound.
HVAC & Mechanical Noise
Noise generated by heating, ventilation, and air conditioning systems that can elevate ambient noise levels and interfere with acoustic testing. Troy designs account for mechanical noise as part of the complete acoustic solution.
Outside Noise Intrusion
External noise from traffic, aircraft, construction, or neighboring facilities entering the space and disrupting operations. Troy’s 72 STC barrier system stops outside noise intrusion while simultaneously containing interior noise.
Muzzle Blast Over-Pressure
The rapid pressure wave generated by gunfire that can cause hearing damage independent of sound levels. The Troy “Caliber” system is the only product rated EXCELLENT by the US Army Corps of Engineers for managing muzzle blast in indoor ranges.

What Our Clients Say
Trusted by Engineers, Architects & Facilities Teams
“Just a short note of thanks and appreciation for the Troy Acoustics materials. They have been installed and look amazing! And they work, too! Noise levels are noticeably improved and it brings a unique contrast to the looks of the shooting booth area. Your work crew was amazing; very polite, helpful, and very hard working.”
— Shooting Range Client
“On behalf of the Rockwall Department I want to express our satisfaction regarding Troy Acoustics assisting us with the research, data collecting and installation of our firing range acoustical system. Troy Acoustics representatives provided overwhelming data that their system was superior to other products reviewed. They extended their guaranteed pricing until we could get all parties to agree on moving forward.”
— Chief Deputy, Rockwall County Sheriff’s Office
“We almost made a big mistake by going with an inferior product because we perceived it to be a less expensive option. When we found out that the Troy System actually cost less, performed better, and had a better warranty, the decision was a no-brainer. The installation crew was professional and the results have been outstanding.”
