For protection against hearing impairment, The Japan Society for Occupational Health specified the Permissible Criteria for Impulse Noise Exposure describing peak sound pressure level and duration of impulse noise. This report discussed the possibility to describe this criteria with measurements indicated on sound level meters which conformed to the new International Standard IEC 61672 (under preparation). Some tests were performed with electrical signals simulated as impulse noises. According to the test results, it appeared that the criteria can be described by maximum A-weighted sound pressure level or A-weighted sound exposure level for A-type impulse noise, and with a combination of peak C-weighted sound pressure level and C-weighted sound exposure level for B-type impulse noise.
