Hearing aid overamplification can cause temporary (TTS) and permanent threshold shifts (PTS). This study found that predicted temporary threshold shifts accurately forecast permanent threshold shifts in children with hearing loss.

Area of Science:

  • Audiology
  • Hearing Science
  • Otoacoustic Emissions

Background:

  • Excessive hearing aid amplification can lead to temporary threshold shift (TTS) and permanent threshold shift (PTS).
  • Understanding the relationship between TTS and PTS is crucial for preventing hearing damage from hearing aids.

Purpose of the Study:

  • To determine if temporary threshold shift (TTS) from hearing aid use can predict permanent threshold shift (PTS).
  • To evaluate prediction models for hearing loss due to excessive amplification.

Main Methods:

  • Predicted asymptotic TTS (ATS) for 8 children with sensorineural hearing loss.
  • Compared predicted ATS with observed PTS after a period of hearing aid use.
  • Utilized the Modified Power Law (MPL) and mean equivalent continuous level (ECL) for predictions.

Main Results:

  • Good agreement was observed between predicted ATS and actual PTS at 500 to 2000 Hz.
  • The MPL method with mean ECL effectively predicted PTS in children with sensorineural hearing loss.
  • The Continuation Hypothesis model underestimated the observed PTS.

Conclusions:

  • Temporary threshold shift (TTS) can serve as a reliable predictor of permanent threshold shift (PTS) from hearing aid use.
  • The Modified Power Law (MPL) with mean equivalent continuous level (ECL) is an appropriate method for predicting PTS.
  • Accurate prediction models are essential for preventing hearing damage associated with hearing aid amplification.
