Temporary threshold shift (TTS) and permanent threshold shift (PTS) are common hearing effects from loud noise exposure. Factors like noise characteristics and individual susceptibility influence their development and severity.

Area of Science:

  • Audiology
  • Occupational Health
  • Acoustics

Background:

  • High-level acoustic stimulation can cause temporary threshold shift (TTS) and permanent threshold shift (PTS).
  • TTS and PTS are the most common auditory effects of acute and chronic noise exposure.
  • Understanding these shifts is crucial for hearing conservation.

Purpose of the Study:

  • To review and discuss the main characteristics of temporary threshold shift (TTS).
  • To review and discuss the main characteristics of permanent threshold shift (PTS).
  • To explore factors influencing TTS and PTS development.

Main Methods:

  • Literature review of studies on acoustic trauma.
  • Analysis of factors contributing to TTS and PTS.

  • Discussion of cochlear function alterations associated with PTS.

    • Main Results:

    • TTS is influenced by stimulus spectrum, exposure level/duration, acoustic reflex, and repetition rate.
    • PTS is associated with exposure duration, age, ototoxic factors, and impulse noise.
    • PTS often leads to impaired speech discrimination, especially in noisy environments.

    Conclusions:

    • TTS and PTS are significant outcomes of acoustic overexposure.
    • Multiple factors contribute to the manifestation and severity of hearing shifts.
    • Further research into mitigating these effects is warranted.
