Examples of inexpensive, effective engineering controls include some of the following: Administrative controls are changes in the workplace that reduce or eliminate the worker exposure to noise. Normally, background noises are at safe levels that do not negatively impact our hearing. On the job, such hearing loss can impact worker communications and safety. FOIA More often, it is caused by long-term exposure to excessive noise, like machine noise, that is present throughout a work shift. Hearing depends on a series of events that change sound waves in the air into electrical signals. The hair cells are arranged with an inner row of about 3,500 hair cells and three to five rows of approximately 12,000 outer hair cells. Occupational hearing loss occurs for two reasons, according to the CDC: loud noise or ototoxic chemicals (solvents, nitriles, and other chemicals can damage the ears, or alternately, make them more susceptible to damage from loud noises).
