NATIONAL FOREWORD
1 Scope
2 Normative references
3 Definitions
4 Description and measurement of exposure
  to noise
5 Prediction of the effects of noise on
  hearing threshold
6 Assessment of noise-induced hearing
  impairment and handicap
Annex A (informative) - Calculation of data
        base A, hearing threshold level associated
        with age (HTLA) for an otologically normal
        population ("highly screened")
Annex B (informative) - Example for data base B
Annex C (informative) - Selected hearing threshold
        levels associated with age
Annex D (informative) - Example of assessment of
        risk of noise-induced hearing impairment
Annex E (informative) - Tables with examples for
        NIPTS data
Annex F (informative) - Bibliography

Describes a method for calculating the expected noise-induced permanent threshold shift in the hearing threshold levels of adult populations due to various levels and durations of noise exposure.
