Abstract (EN):
The aim of this article was to analyse the actual issues about the sound level limits that cause Noise Induced Hearing Loss (NIHL). It was done a systematic review irected to the search in the electronic databases: SCOPUS®, WEB OF SCIENCE® and PUBMED®. The obtained results lead to some crucial aspects when NIHL is assessed. These shortages are related to assumptions that must be taken in account: contribution of non-occupational noise, impulsive noise, susceptibility to noise and use of hearing protection. Non-occupational noise, in some circumstances, can have a significant contribution for NIHL. The impulsive noise, which can also be found in non-occupational noise, has a particular contribute to NIHL and it is basically neglected. Individual susceptibility can also be an important factor. By other way, the audiometry and the use of hearing protection could infer a large bias. The actual limit levels don¿t contemplate the integration of all this variables. © 2015 Taylor & Francis Group, London.
