Hey Guys,
Just wanted to let you know that we've altered our sound testing technique a bit. Instead of just continuing on with the standard PEAK impulse decibel data, we wanted to provide more information for customers regarding dosing data.
We contacted Hottinger Brüel & Kjær, inquiring how we'd be able to utilize our equipment and software to do such. They recommended researching the US Army Development Command's Army Research Laboratory AHAAH (Auditory Hazard Assessment Algorithm for Humans), as this is a supported function in the HBK PULSE LabShop software we possess.
Peak decibel data will still be present, as that is the loudest portion of the waveform, but this will be accompanied by more info. Data will include :
- Peak dB sound pressure level reading
- LAeq A-weighted Equivalent Continuous Sound Pressure Level (average A weighted dB sound pressure for the waveform over the defined time in milliseconds)
- Leq Unweighted Equivalent Continuous Sound Pressure Level (average unweighted dB sound pressure for the waveform over the defined time in milliseconds)
- Number of exposures with no protector worn, "warned" (how many gun shots would be safe to fire or be in the immediate vicinity of, daily and weekly, for an anticipating observer) applying to 95% of the exposed population
- Source document of waveform graphic and table
- Descriptive summary of testing

HERE IS OUR NEWEST VIDEO USING THIS NEWLY INCORPORATED STANDARD :
Prior to using this new (to us) sound test method, we've been including flash data for the suppressors tested. These videos include photos showing the flash signature of FRP, Shot #2, & Shot #3 of the listed suppressors :
