Abstract:

Statement of the problem: There are many classifications of hearing losses caused by high sound pressure levels, usually occurred in worker´s environment. The authors propose a simple way to follow the evolution of the hearing losses. In order to prevent early potential increase of these losses. Methodology & Theoretical Orientation: By means of a graphic study of the disposition of the losses in the audiometric graphics using a three graphics delimitator, the author’s classified the hearing losses in six types: Normal, I, II, III, IV and Not Related to Sound Pressure Levels (NRTSPL). Comparing the result of the classification the staff would be able to understand about a possible or an impossible relationship on the context in which it occurs and its evolution, based on the worker’s journey of work and the effective levels of exposure. Findings: Based on their experience on the analyses of more than 45,000 audiograms in workers at risk of exposure to high sound pressures levels in their work environment in about 35 years, performed each one by themselves, they propose this classification to make easier the analyses of each case, by work medicine doctor’s which is not familiar with otolaryngology or otology. Figure 1. Example of the audiogram chart with its fields used for the classification. Conclusion: The hearing loss probably caused by effective exposition to high pressure levels sounds can be easily followed on their evolution by medicine doctor’s which are not familiar with this kind of hearing disease, in order to adopt as early as possible preventive measures, to avoid the increase of the hearing loss, until the specialist can analyze the best way to prevent bigger problems.
