Título Interim Guidelines on Limits of Human Exposure to Airborne Ultrasound
Resumo These guidelines are primarily aimed at protection against exposure from devices emitting limited to frequencies having one-third-octave bands and guidance is given on limits of human exposure to airborne acoustic energy in the ultrasound range. Adverse health effects of exposure to airborne acoustic energy at levels normally encountered have been reported only at frequencies below 100 kHz and nearly all below 50 kHz. Thus, this standard has been limited to frequencies having one third-octave bands with mid frequencies from 20 kHz to 100 kHz.
