Assessment of central auditory processing in a group of workers exposed to solvents.

CONCLUSION: Despite having normal hearing thresholds and speech recognition thresholds, results for central auditory tests were abnormal in a group of workers exposed to solvents. Workers exposed to solvents may have difficulties in everyday listening situations that are not related to a decrement in hearing thresholds. A central auditory processing disorder may underlie these difficulties. OBJECTIVE: To study central auditory processing abilities in a group of workers occupationally exposed to a mix of organic solvents. MATERIALS AND METHODS: Ten workers exposed to a mix of organic solvents and 10 matched non-exposed workers were studied. The test battery comprised pure-tone audiometry, tympanometry, acoustic reflex measurement, acoustic reflex decay, dichotic digit, pitch pattern sequence, masking level difference, filtered speech, random gap detection and hearing-in-noise tests. RESULTS: All the workers presented normal hearing thresholds and no signs of middle ear abnormalities. Workers exposed to solvents had lower results in comparison with the control group and previously reported normative data, in the majority of the tests.

Organic solvents and hearing loss: The challenge for audiology.

Organic solvents have been reported to adversely affect human health, including hearing health. Animal models have demonstrated that solvents may induce auditory damage, especially to the outer hair cells. Research on workers exposed to solvents has suggested that these chemicals may also induce auditory damage through effects on the central auditory pathways. Studies conducted with both animals and humans demonstrate that the hearing frequencies affected by solvent exposure are different to those affected by noise, and that solvents may interact synergistically with noise. The present article aims to review the contemporary literature of solvent-induced hearing loss, and consider the implications of solvent-induced auditory damage for clinical audiologists. Possible audiological tests that may be used when auditory damage due to solvent exposure is suspected are discussed.

Auditory processing tests for Spanish-speaking adults: an initial study.

There is no standardized material to assess auditory processing (AP) in Spanish-speaking adults. The purpose of this research was to develop and obtain initial normative data for AP tests for Spanish-speaking adults. The AP tests comprised the Hong Kong CAPA (Hong Kong central auditory processing assessment) including speech-in-noise, binaural fusion, filtered speech, and dichotic digit tests. In addition five tests already developed by other authors, but with no normative data reported for the target population, were included in the study. These tests were staggered spondaic words, random gap detection, pitch pattern sequence, duration pattern sequence, and masking level difference. Forty normal hearing Chilean adults were assessed to obtain the initial normative data. Several correlations were found between tests and between subtests within the same test category. 90th percentiles are suggested as initial normative data.
