Given the choice, most sensible people would not knowingly choose to put themselves in an environment that was considered hazardous to their health. However, many patrons are unaware of the potential danger of sustaining permanent hearing loss and are also unaware of the fact that noise levels over 85 dBA are dangerous. An informed public, coupled with rational behavior, are key ingredients in the protection of individuals from both hearing lossand extra health costs. Enforcement of existing work place laws should protectnightclub employees, patrons, teachers, musicians, D.J's or any other individual who may be exposed to dangerous noise levelsthat could pose a potential health hazard. Regretfully, such laws are very seldom implemented or enforced.
Critical bands allow discrimination of different sounds simultaneously.
Hearing loss is often accompanied by damage to the critical bands,which in some situations can profoundly change ear's selectivity. Therefore they do not compensate for this deficiency. 50 dB loss it will take 100,000 birds and with 60 dB loss it will take 1,000,000 birds. Please wear hearing protection in the situations like that.
