Impact DBLBO dB Buster Acoustic Tube Elbow Filter for Two-Way Radio Surveillance Kit (OSHA Compliant). Our dB Buster„¢ elbow filters are OSHA-compliant. They meet the OSHA 8-hour shift standard by lowering the maximum audio output to below 90dB. The dB Buster elbow filters are the perfect choice when also wanting to block high levels of ambient noise and still clearly and safely hear your radio transmission, making them ideal for shooting, construction, industrial applications, and loud music venues. Use as an option on all standard coil and straight acoustic tube products and/or order your surveillance kits fitted with this fantastic technology. Or, purchase them separately to easily install on any IMPACT or other brand acoustic tube audio accessory. The filter uses the accelerated resonant decay principle to convert sonic energy into thermal energy by means of compression acceleration. In plain English, this means the dB Buster earplugs block high levels of ambient noise and still allow you to clearly and safely hear your radio transmission. They bounce part of the dangerous incoming noise back out of your ear, and that piece of sound partially cancels out the incoming noise, thus reducing it to a safe volume level. The louder the dangerous noise, the more of it that gets automatically cancelled out. As a result, no sound over approximately 85 decibels is allowed to pass through the filter into your ear.
