Acoustic Safety and Innovation in Shooting Ranges: The Himalayan Acoustics Solution

Introduction: The Acoustic Challenge in Shooting Ranges

Shooting ranges present a unique and critical acoustic environment where sound pressure levels (SPL) can reach up to 160 dB, a level known to cause temporary deafness and, with prolonged exposure, permanent hearing loss. Human ear membranes are highly sensitive, and despite medical advancements, they cannot be repaired once damaged.

Given these hazards, it becomes essential to acoustically treat shooting ranges to maintain a reverberation time (RT60) below one second, thereby reducing SPL levels and enhancing safety for users.

• Peak sound levels from gunfire can exceed 160 dB, posing immediate health risks.
• Prolonged exposure (even over an hour) can lead to permanent hearing loss.

• Poor acoustic treatment results in high reverberation times, amplifying noise and increasing SPL levels.

• Sound waves in shooting ranges are divided into low (100-250 Hz), mid, and high frequencies, all of which need proportional absorption for effective sound control.

• Insufficient soundproofing allows noise leakage, disturbing surrounding environments.

• Many market-available acoustic products are chemically treated and non-fire retardant, releasing toxic fumes when exposed to high-caliber weapon heat.

Himalayan Acoustics offers a range of high-performance acoustic solutions that effectively absorb sound waves across all frequency ranges and maintain RT60 below one second.

• Aphony Fibrette and Aphony Gloss Range:
• Achieves NRC (Noise Reduction Coefficient) of 1+, providing superior sound absorption for frequencies between 100 to 250 Hz.
• Acts as a shock wave absorber, minimizing reverberation.

To prevent noise from escaping the shooting range, Himalayan Acoustics offers:

• Sound Dampeners and Sound Barriers with Dampeners:
• Block noise leakage and reduce SPL levels outside the range.
• Acoustic Doors:
• Designed to offer superior sound insulation while maintaining safety and functionality.

• Fire Retardant and Smoke-Free: Products meet stringent fire safety standards, ensuring safety in high-caliber weapon environments.
• Non-Toxic: Manufactured without harmful chemicals, ensuring a safe and healthy environment for users.

• Reverberation Time (RT60): Achieved reduction from 3+ seconds to below 1 second in treated shooting ranges.
• Noise Reduction Coefficient (NRC): Rated at 1+, ensuring effective absorption across low, mid, and high frequencies.
• Sound Transmission Loss (STL): Reduction of up to 45 dB outside the shooting range when using sound dampeners and acoustic doors.
