description | Introduction: The noise causes effects on the hearing and all organism. In hearing it may produce a threshold temporary shift (TTS): for a short term the auditory sensitivity is increased due to the metabolic exhaustion of the hair cells in the presence of intense sounds. When the noise is eliminated, the hearing returns to its normal threshold. The individuals who work exposed to noise may acquire a permanent threshold shift (PTS). One of the ways to avoid the TTS/PTS is using the auditory protection when in the presence of noise. Objective: The objective of this research was to verify the efficacy of the auditory protections used by workers exposed to noise of 96.5 dB (L) in a metallurgic factory in the countryside of the State of São Paulo. Method: Tonal audiometry before and after the working journey in 13 workers users of auditory protection of insertion type, exposed to 96.5 dB (L), to determine whether there is TTS. Results: We confirmed that the hearing of workers did not undergo statistically significant audiometric thresholds shifts between the pre-journey and post-journey exam. Conclusion: This research showed that the use of auditory protections of insertion type was efficient, because it did not produce TTS in the workers exposed to noise. |
