This guide details an experiment from Collapse N Protect demonstrating a DIY method for reducing revolver noise using a towel. While the experiment shows a 25 dB reduction, it highlights that this method does not achieve hearing-safe levels. The content is presented by a firearms enthusiast with expertise in sound measurement and firearm handling.

This video debunks the Hollywood myth of 'silent' silencers, demonstrating through decibel measurements that suppressors significantly reduce firearm noise but do not eliminate it, especially with supersonic ammunition. Instruction from a firearms expert highlights the acoustic realities of suppressed shooting and the importance of accurate terminology.

This comprehensive review by an expert instructor details the performance of the OSS Helix IFM 762 suppressor. It highlights the unique flow-through design, comparing its at-ear decibel readings to traditional suppressors like the Dead Air Sandman-L. The analysis includes industry-standard and military-standard testing, accuracy assessments at 100 and 500 yards, and a demonstration of low gas blowback during sustained fire. The instructor emphasizes the importance of at-ear measurements for hearing safety.

This video features a sound test of a suppressed 500 S&W Magnum lever-action rifle. The Bighorn Armory Model 89, equipped with a Bowers Vers 50 suppressor, was tested using MagTek 325-grain bullets. The test measured decibel levels with and without the suppressor, demonstrating the significant noise reduction provided by the suppressor.

This video provides a scientific evaluation of various .30 caliber suppressors, conducted by an expert with high authority in firearms and tactical gear. It details testing methodologies, including the use of professional sound metering equipment and specific rifle platforms, to measure decibel reduction. The expert emphasizes hearing safety, noting that many suppressed firearms still exceed safe decibel levels, and cautions against relying on inaccurate measurement tools.
