Prediction of NIPTS, Hearing Impairment and Handicap

• Description:
  A method was developed for predicting noise induced permanent threshold shift (NIPTS) based on exposure to steady, intermittent, and impulsive noises. Information on pure tone hearing level, speech intelligibility test scores, and self rated hearing ability was derived from a random sample of the general public. The ISO Standard 1999 was found to underestimate NIPTS from exposure to continuous steady noise for an 8 hour workday. The Standard overestimated NIPTS from interrupted steady noise and impulsive/impact noise. Nonoccupational noise exposures, particularly to gun noise, were significantly able to obfuscate hearing losses resulting from the exposure to occupational noise. The new method, Effective Energy, A-weighted (EEA) was able to predict hearing loss from continuous or interrupted steady and impulsive type noises with reasonable accuracy.
