The louder the noise is, the shorter the safe amount of exposure is. Normally, the safe amount of exposure is reduced by a factor 2 for every additional 3 dB(A). For example, the safe daily exposure amount at 85 dB is 8 hours, while the safe exposure at 91 dB(A) is only 2 hours. Personal electronic audio devices, such as iPods (iPods often reaching 115 decibels or higher), can produce powerful enough sound to cause significant noise-induced hearing loss, even though lesser intensities of even 70 dB can also cause hearing loss. Hope this helps. :D A level of 70 db(A) for 24 hour exposure is the level necessary to protect yourself from hearing loss. The louder the noise is, the shorter the safe amount of exposure is.
