The rate of hearing loss caused by the work environment has fallen gradually in the American private industry between 2004 and 2010, dropping from 3.2 cases to 2.2 cases per 10,000 full-time workers.
Small proportion of hearing loss claims
The proportion of hearing loss claims is also significantly smaller than with other kinds of insurance claims, according to the California Workers' Compensation Institute, a private, nonprofit organization of workers' compensation insurers.
“For each year since 2004, claims in which the primary diagnosis was hearing loss have accounted for between 0.05% and 0.06% of all claims in the ICIS database, so the volume of claims is extremely small and the trend is flat,” said Bob Young, Communications director at the institute.
The Institute maintains the Industry Claims Information System (ICIS), which contains about 3.5 million California workers' compensation claims from 2000-2012.
