The influence of loud music on hearing thresholds by the use of personnal cassette players: study of otoacoustic emissions (distortion product) and audiometry in 40 ears

Introduction: Transient or permanent cochlear lesions due to exposure to loud intensity music have been studied by a great number of authors. Noise induced hearing loss has been extensively studied using audiometry and otoacoustic emissions (distortion product), but both tests have never been compared. Study design: Prospective clinical no randomized. Aim and Method: The authors aimed at investigating audiometric and otoacoustic alterations and clinical manifestation in 20 volunteers (40 ears) exposed to loud intensity music for 60 minutes using a personal cassette player. Conclusion: The present study confirmed the incidence of Temporary Threshold Shift (TTS) after exposure to loud intensity music, especially in 4 kHz and 6 kHz.
