Audiologists are trained to use standard techniques to obtain accurate, consistent results. When results are obtained carelessly, or recorded illegibly, the audiogram may be useless. This is particularly true when the results are to be used for determination of a worker's compensation or in medicolegal cases, as in the following examples.
A worker retired after 30 years of work in an industry with excessive noise levels. The company did not dispute that the worker should receive compensation. The worker presented two audiograms taken 8 months and 15 months after retirement. The first audiogram, performed by a certified audiologist in an otolaryngologist's office, showed thresholds that were recorded carelessly, making it difficult to determine whether each frequency had been tested and the exact level at each frequency. The second, from another site, also by a certified audiologist, did not include testing at 3000 Hz. Neither audiogram allowed determination of percent loss using the formula described in the state compensation law. The formula requires threshold levels at 500, 1000, 2000, and 3000 Hz.
