Unless you work for Redjacket you will need at least 5 grand to have a meter that will capture the impulse of a gun shot.
Will thinks 140db is hearing safe so what difference does there meter make?
Actually it has been posted on other sites that at least in the UK, noise levels must be at or below 140db. THis number is apparently their standard for industrial noise as well as gun noise being safe for human hearing. So........it was not necessarly all Will's idea. Maybe someone from accross the pond would like to elaborate more on this
Uk noise at work regulations since 2006, mandatory ear protection required by law must be worn at 85dB and above, this was reduced from 90dB previously.
Generally at 80dB hearing protection is provided if requested.
