Scope

This standard specifies the calculation method for the noise-induced permanent threshold shift (NIPTS) expected to occur in adults at different noise exposure levels and durations; it proposes the basic principle of calculating hearing impairment using various formulas at commonly used audiometry frequencies or certain combinations of frequencies when the hearing threshold exceeds the specified value.
