Evaluation of a Loudness Discrimination Test.
Abstract
Recent research has demonstrated that temporary changes in loudness perception occur following high level noise exposure. Two pilot studies and an experiment are presented in this study which evaluates a noise-induced loudness perception test. The first two experiments investigated the feasibility of several loudness perception test parameters. The third experiment described a loudness Discrimination Growth Test (LDGT) which is based on the information obtained in the first two experiments. This LDGT was evaluated in terms of clinical feasibility, reliability, and sensitivity. The findings suggested that the LDGT is reliable, is affected by the spectral content of the exposure sound, and measures noise-induced temporary auditory change that is different from a temporary threshold shift growth test. With further research, this LDGT could be incorporated into a test battery for use in identifying those individuals who are sensitive to noise-induced auditory changes possibly before they develop permanent auditory impairment.
