Occupationally-Induced Hearing Loss

March 2010
DHHS (NIOSH) Publication Number 2010-136
cover of 2010-136

There are an estimated 16 million people working in the Manufacturing Sector, which accounts for approximately 13% of the U.S. workforce. According to the Bureau of Labor Statistics, occupational hearing loss is the most commonly recorded occupational illness in manufacturing (17,700 cases out of 59,100 cases), accounting for 1 in 9 recordable illnesses. More than 72% of these occur among workers in Manufacturing. These numbers are particularly disturbing considering that a person’s hearing loss must be determined to be work-related and the hearing loss must be severe enough that the worker has become hearing impaired, in order to be OSHA-recordable. Many more workers would have measurable occupational hearing loss but would not yet have become hearing impaired.
