Cochlear Hearing Loss

Three assumptions involved in the rationale for loudness tolerance modification were investigated: (1) that an abnormal loudness discomfort level (LDL) is modifiable by sub-LDL stimulation, (2) that a relationship exists between abnormal LDL and reduced speech discrimination ability, and (3) that an improved LDL will result in better speech discrimination than evidenced before such modification. Twenty subjects with functional evidence of bilateral cochlear hearing loss were divided into four group. Each of three groups received a different type of sound exposure and the other groups served as a control. LDLs were determined before, interjacent to, and after exposure. No significant changes in LDL were found for any of the experimental groups. The parabolic articulation function associated in the literature with monaural cochlear lesions was absent for all cases. Sub-LDL exposure to high intensity speech does not appear to be an effective modifier of an abnormal LDL. The rationale for loudness discomfort level modification therapy, namely to improve speech discrimination, appears to be unwarranted. Abnormal loudness discomfort improvement may involve adjustment problems more responsive to behavioral modification approaches.

Word Discrimination

Noise exposure in the workplace and the recreational environment probably accounts for more new cases of tinnitus and hearing loss than all other causes combined. To an increasing degree, preemployment audiograms of late teenagers and those in their early twenties show noise-induced, sensorineural ‘notches’ greatest at 4000 or 6000 Hz with partial or complete recovery at 8000 Hz. Word discrimination tests, as typically evaluated in a clinical situation, show essentially normal findings although more difficult measures of consonant discriminations such as the California Consonant Test or conventional speech tests in a background of noise often demonstrate impaired word discrimination ability.

Poorly Differentiated

In an attempt to improve the differentiating ability of monosyllabic speech discrimination tests, two equivalent, 25-word test recordings with rectilinear distributions of item difficulty were constructed from W-22 Hirsh recordings. These lists and selected half lists of the standard W-22 recordings were then presented to 40 ears of listeners with losses ranging in severity from -10 dB to 60 dB (SRT) at sensation levels of 20, 30, 40, and 50 dB. Scores obtained with the new lists describe a less skewed frequency distribution than those obtained with the W-22 half lists. The new recordings were also more successful in differentiating between subjects with varying levels of sensorineural hearing losses, particularly between normal-hearing listeners and listeners with mild loss, who are usually poorly differentiated by W-22 tests. This was accomplished without resorting to deliberate distortion of stimulus words. These new recordings appear to have clinical usefulness in their ability to more accurately reflect differences in discrimination ability among listeners and particularly in their ability to reveal reduced discrimination in mild sensorineural hearing loss.

Reliability Coefficients

The reliability and intercorrelations of selected lists from the clinical version of the Modified Rhyme Test (MRT) were examined using normal-hearing young listeners and older listeners believed to have incurred noise-induced hearing loss. Stability of means and variances was generally acceptable for the lists of the MRT, but the reliability coefficients and intercorrelations were generally low. In its present state, the clinical MRT appears to lack the precision to discriminate among normal young listeners, if normal young listeners really do differ in speech discrimination ability with a closed response set. We do not yet have adequate knowledge of the range of expected normal performance for the MRT. The MRT appears far more reliable when used with a much more heterogeneous hearing loss population.

Factors Influencing

In our paper we would like to emphasize the complexity of hearing aid prescription process. It is connected to a series of factors which impact the choice of hearing aid; type of hearing loss, degree of hearing loss according to the average hearing threshold expressed within the range from 500 Hz to 4000 Hz on a tonal audiogram, audiometric curve configuration, speech discrimination ability, patients? age at which the hearing impairment occurred, time elapsed between the occurrence of hearing impairment and prescription of a hearing aid, patients? age, physical and mental health and their cognitive function, anatomical characteristics of the auricle and external auditory canal, patient and parent motivation, cosmetic factors, financial abilities, cooperation with hearing aids manufacturers. This paper is important for everyday practice and can be used as a kind of guideline to the hearing aid prescription process.

The Relationship

The relationship between diabetes and senbsorineural hearing loss has been disputed. This study compares 44 insulin-dependent diabetics with 38 age and sex matched controls. All had pure tone and speech audiometry performed, with any diabetics showing sensorineural deafness undergoing stapedial reflecx decat tests. In 14 diabetics stapedial reflex tests showed no tone decay in any patient, but seven showed evidence of recruitment. Analysis of vaiance showed the diabetics to be significantly deafer than the control population.The hearing loss affected high frequencies in both sexes, but also low frequencies in the male. Speech discrimination scores showed no differences. Further analysis by sex showed the males to account for most of the differences. Analysys of the audiograms showered mostly a high tone loss. Finally duration of disbetes, insulin dosage and family history of diabtes were not found to have a significant effect on threshold.

Verbal Development

Histories of ear disease, otoscopic examinations, and audiologic, intelligence, and achievement tests were obtained from a cohort of 489 Alaskan Eskimo children who have been followed through the first ten years of life. Seventy-six per cent had experienced one or more episodes of otitis media since birth. Of these, 78% had their first attack during their first two years of life. Perforations and scars were present in 41%. A hearing loss of 26 decibels or greater was present in 16%, and an additional 25% were in the normal range but had a measurable air-bone gap. Children with a history of otitis media prior to 2 years of age and a hearing loss of 26 decibels or greater had a statistically significant loss of verbal ability and were behind in total reading, total math, and language. In addition, children who had an early onset of otitis media but now had normal hearing with a conductive component were also adversely affected in verbal areas. The number of otitis media episodes was related to tympanic membrane abnormalities, hearing loss, and low verbal and achievement scores. These findings indicate that otitis media has been a significant cause of morbidity in Alaskan Eskimo children, and its onset during the critical years of language development as well as the number of episodes play an important role in impairing verbal development.
