Hearing-conservation training exam. What part of the ear is damaged as a result of hazardous noise ? True or False The impairment caused by a noise-induced sensorineural hearing loss essentially can be reversed through the use of modern hearing aids. Hearing loss can affect job retention and exclude workers from certain career fields. One-time exposure to an intense percussive sound such as an explosion can cause hearing loss. Continuous or repeated exposure to loud sounds over an extended period of time such as using a personal listening device at high volume can also lead to hearing loss. Sound is measured in units called decibels or dB. d. Two main factors that determine whether hearing loss is likely to result from loud noise exposure are: intensity (the loudness level of the sound) and duration of exposure (how long you are around the noise ). So by limiting the intensity and/or the duration of exposure you reduce the likelihood of acquiring hearing loss. Exposure to Noise . If so protect your hearing with good quality ear-plugs or earmuffs. Per OSHA hearing protection should be worn anytime the noise level exceeds these two decibel-level thresholds: 85 dB and 90 dB. For all employers including those in construction OSHA requires a hearing conservation program for workers exposed to 85 dB... There are a couple of ways you can determine whether the noise level in your workplace is hazardous to your hearing. The first is the “arm’s length rule”: if you have to raise your voice to be heard by a co-worker an arm’s length away the noise level is potentially dangerous. The National Institutes of Health Consensus Development Conference on Noise and Hearing Loss brought together biomedical and behavioral scientists health care providers and the public to address the characteristics of noise-induced hearing loss acoustic parameters of hazardous noise exposure individual and age-specific susceptibility and ...
