The purpose of the investigation was to explore the relationship between hearing level at various audiometric frequencies and speech discrimination in different noise backgrounds. The study was designed specifically to test the American Academy of Ophthalmology and Otolaryngology's (AAOO) selection of a 26-dB average of 500, 1000, and 2000 Hz, as the point above which hearing handicap occurs. The AAOO method for computing hearing handicap has lately been brought into question for two primary reasons: that the 26-dB fence is too high, and for the exclusion of frequencies above 2000 Hz. The following experimental questions were posed: (1) What is the relationship between average hearing level at 500, 1000, and 2000 Hz and speech discrimination scores in noise for individuals whose average hearing levels are at or better than the AAOO low fence; (2) Is the relationship dependent upon speech-to-noise ratio; (3) Is the relationship between average hearing level and speech discrimination scores differently described by different speech materials; and (4) Which combination of audiometric frequencies best predicts speech discrimination scores.

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

This study evaluated the relationships of speech discrimination measures obtained in quiet and in noise with various distortion indexes with a group of subjects with sensorineural hearing loss. The results indicated that the most important factors associated with speech intelligibility were the extent and configuration of the hearing loss. The inter-relationships among DL tests for frequency and intensity, linear range measures, age, and pure-tone thresholds were examined. Comparisons were made with normal-hearing listeners.

Navy personnel with normal hearing and with hearing losses at 3 kHz and above were evaluated on tests of speech discrimination in noise. Two tests were used, one previously designed for use in audiological clinics and one constructed at this laboratory with background noise similar to that found in the enginerooms of nuclear submarines. The results indicate that subjects with hearing losses at 3 kHz and above may score as much as 11 per cent more generally at least five per cent below normals for a speech discrimination task in noise. For the two types of noise used in these tests, there was little or no difference in the general trend of test results. The correlation coeffieients obtained between the pure tone audiometric findings and the speech discrimination task in noise were found to be nonsignificant for the most part. From these results, it appears that hearing loss at 3 kHz reduces one's ability to discriminate speech in noise but this reduction is minor.
