does anyone have an electronic copy of the following standards ?
Acoustics - Framework for calculating a distribution of sound exposure levels
for impulsive sound events for the purposes of environmental noise assessment
Acoustics - Determination of occupational noise exposure and estimation of
noise-induced hearing impairment
Evaluation Of The Potential Effect On Human Hearing Of Sounds With
Peak-a-weighted Sound Pressure Levels Above 120 Decibels And Peak-c-weighted
Sound Pressure Levels Below 140 Decibels
The ANSI standard is withdrawn and I don´t know whether it´s superseded by another.
