The purpose of this study was to determine if peripheral hearing loss of varying degrees in elderly subjects affected performance on monotic auditory processing disorder (APD) tests. A battery of monotic APD tests was administered to a group of well-educated and high-functioning older adults who were divided into three subgroups based on hearing acuity but similar in age: (1) normal hearing out to 4000 Hz with a slight high-frequency slope above that point, (2) normal hearing in the speech range but greater high-frequency loss (sloping configuration), and (3) hearing loss in both the low and high frequencies (low/high). The findings documented that subjects with normal hearing in the speech range performed well on all the APD tests. The subjects in the two hearing loss groups, however, performed more poorly on certain tests. The low/high loss subjects did significantly poorer than did the sloping subjects. These data suggest that low/high-frequency peripheral hearing loss is a factor for poor performance on certain monotic APD tests. Results further showed that when cognitive ability and presentation level are held constant, chronological age does not appear to be a contributing factor to performance on the majority of these monotic APD tests. If APD tests are to be administered to elder subjects, peripheral hearing loss configuration needs to be documented. For subjects with low/high-frequency losses, the tester needs to be aware that serious contamination of the results may occur. El propósito de este estudio fue determinar si las pérdidas auditivas periféricas de diferentes grados en sujetos mayores afectaban el desempeño en pruebas monóticas para trastornos de procesamiento auditivo (APD). Una batería de pruebas monóticas para APD fue administrada a un grupo de adultos mayores bien educados y con alto nivel de funcionamiento, quienes fueron divididos en tres subgrupos con base en su agudeza auditiva, pero con edad similares: (1) audición normal hasta 4000 Hz pero con una leve pendiente en las frecuencias agudas por encima de ese punto, (2) audición normal en el rango del lenguaje pero con una pérdida mayor en frecuencias agudas (configuración en caída), y (3) pérdida auditiva tanto en frecuencia agudas como en altas (baja/alta). Los hallazgos documentaron que los sujetos con audición normal en el rango del lenguaje se desempeñaron bien en todas las pruebas APD. Los sujetos en los dos grupos de pérdida auditiva, sin embargo, se desempeñaron más pobremente en ciertas pruebas. Los sujetos de alta/baja rindieron significativamente peor que los sujetos de configuración en caída. Estos datos sugieren que la hipoacusia periférica en frecuencias altas/bajas es un factor de pobre desempeño en las pruebas monóticas en APD. Los resultados mostraron además que cuando la habilidad cognitiva y los niveles de presentación se mantienen constantes, la edad cronológica no parece ser un factor modificador del desempeño en la mayoría de estas pruebas monóticas en APD. Si se han de administrar estas pruebas para APD a adultos mayores, la configuración de la pérdida auditiva periférica debe ser documentada. Para sujetos con pérdidas auditivas en frecuencias bajas/altas el evaluador debe ser conciente de que puede ocurrir una seria contaminación de los resultados.

This study examined the performance of four subject groups on several temporally based measures of auditory processing and several measures of speech identification. The four subject groups were (a) young normal-hearing adults; (b) hearing-impaired elderly subjects ranging in age from 65 to 75 years; (c) hearing-impaired elderly adults ranging in age from 76 to 86 years; and (d) young normal-hearing listeners with hearing loss simulated with a spectrally shaped masking noise adjusted to match the actual hearing loss of the two elderly groups. In addition to between-group analyses of performance on the auditory processing and speech identification tasks, correlational and regression analyses within the two groups of elderly hearing-impaired listeners were performed. The results revealed that the threshold elevation accompanying sensorineural hearing loss was the primary factor affecting the speech identification performance of the hearing-impaired elderly subjects both as groups and as individuals. However, significant increases in the proportion of speech identification score variance accounted for were obtained in the elderly subjects by including various measures of auditory processing.

Seven normal-hearing subjects and seven subjects with mild bilateral high-frequency sensorineural hearing losses were studied to explore the presence of diplacusis. A tracking procedure of psychophysical method of adjustment-limits was used for pitch judgments rather than the traditional method of adjustment. Each subject was presented with a standard 4000-Hz tone for 500 msec and alternately a variable tone for 500 msec. Subjects were instructed to adjust the variable tone upward or downward in pitch to bracket the pitch sensation of the standard tone. Two intra-aural and two interaural listening conditions were studied. A graphic representation of the subjects' adjustments of the variable tone was obtained for each condition. The resulting tracing indicated frequency correlates to the pitch adjustments from which excursion width and constant error were calculated. Some hard-of-hearing subjects and one normal-hearing subject were found to have diplacusis. Subjects with hearing losses exhibited larger excursion widths for intra- and interaural listening conditions. Subjects with hearing losses tended to be less consistent in pitch judgments than normal-hearing subjects. These findings were interpreted to mean that bilaterally symmetrical hearing losses increase the incidence of pitch aberrations.

Monaural envelope correlation perception was investigated in listeners with normal hearing and in listeners with cochlear hearing loss. Using a three-interval forced-choice procedure, the task of the subject was to identify the one interval out of three where the noise bands had correlated envelopes. Performance was determined as a function of the spectral separation between noise bands (Δf of 250, 500, or 1000 Hz) and the number of noise bands present (two, three, or five). Although individual differences existed, the results generally indicated better performance for the listeners with normal hearing when the Δf between bands was relatively small; however, there was no significant effect of hearing loss when the frequency separation between bands was greater than 250 Hz. The listeners with normal hearing generally showed decreased performance with increasing Δf, whereas the performance of many of the listeners with hearing impairment usually did not change appreciably with variation in Δf. Both groups of listeners showed improved performance with increasing number of noise bands present for the 500-Hz Δf. Only the listeners with hearing impairment showed significantly improved performance with increasing band number for the 250-Hz Δf; neither group showed improved performance with increasing band number for the 1000-Hz Δf. With five bands present, the performance of the listeners with hearing impairment did not differ significantly from that of the listeners with normal hearing, even for the 250-Hz Δf. It is possible that the poor performance of many of the listeners with hearing impairment when Δf is small may be due to relatively poor peripheral frequency analysis. It is difficult to determine the role of within-channel versus across-channel cues in the effects obtained.

The purpose of this study was to assess the consonant and vowel identification abilities of 12 children with minimal high-frequency hearing loss, 12 children with normal hearing, and 12 young adults with normal hearing using nonsense syllables recorded in a classroom with reverberation time of 0.7 s in two conditions of: (1) quiet and (2) noise (+13 dB S/N against a multi-talker babble). The young adults achieved significantly higher mean consonant and vowel identification scores than both groups of children. The children with normal hearing had significantly higher mean consonant identification scores in quiet than the children with minimal high-frequency hearing loss, but the groups performances did not differ in noise. Further, the two groups of children did not differ in vowel identification performance. Listeners’ responses to consonant stimuli were converted to confusion matrices and submitted to a sequential information analysis (SINFA, Wang & Bilger, 1973). The SINFA determined that the amount of information transmitted, both overall and for individual features, differed as a function of listener group ad listening condition.

Vast literature exists detailing the identification and management of central auditory processing disorder in children: however, less information is available regarding central auditory processing disorder in the adult population. This study aimed to document the diagnostic and management procedure for adults presenting at a multidisciplinary clinic due to concerns regarding their listening and central auditory processing skills. This retrospective study was a case file audit of two adults (a male, aged 37 years and a female, aged 44 years) who presented at a multidisciplinary (audiology and speech pathology) clinic for a hearing and central auditory processing evaluation. Both participants completed a case history questionnaire and were then interviewed with results being documented in their file. Participants were evaluated by a dually qualified audiologist-speech pathologist on a battery of peripheral hearing tests (including pure-tone threshold audiometry, immittance measures and speech tests), central auditory processing assessments (including monaural low redundancy, dichotic listening and temporal processing tests) and evaluation of short-term auditory memory skills. Participants were self-referred, never having been assessed previously for central auditory processing disorder, yet had perceived heightened difficulty with processing information; having conversations (particularly in noisy work or social environments) and remembering information, resulting in a range of psychosocial responses. Following diagnosis of central auditory processing disorder, participants undertook an individualized short-term aural rehabilitation program as dictated by their needs and preferences. Post-program participants perceived better ability to listen and process information even in adverse listening conditions. They reported that their newly learned skills improved their work abilities and social participation leading to positive outcomes. Medical and other allied health professionals should consider the possibility of presentation of central auditory processing disorder in adulthood and make appropriate referrals for central auditory processing testing to facilitate diagnosis and appropriate intervention. Aural rehabilitation should be considered for adults newly diagnosed with central auditory processing disorder.

Objective. The majority of tinnitus patients suffer from hearing loss. But a subgroup of tinnitus patients show normal hearing thresholds in the conventional pure-tone audiometry (125 Hz–8 kHz). Here we explored whether the results of the high frequency audiometry (>8 kHz) provide relevant additional information in tinnitus patients with normal conventional audiometry by comparing those with normal and pathological high frequency audiometry with respect to their demographic and clinical characteristics.Subjects and Methods. From the database of the Tinnitus Clinic at Regensburg we identified 75 patients with normal hearing thresholds in the conventional pure-tone audiometry. We contrasted these patients with normal and pathological high-frequency audiogram and compared them with respect to gender, age, tinnitus severity, pitch, laterality and duration, comorbid symptoms and triggers for tinnitus onset.Results. Patients with pathological high frequency audiometry were significantly older and had higher scores on the tinnitus questionnaires in comparison to patients with normal high frequency audiometry. Furthermore, there was an association of high frequency audiometry with the laterality of tinnitus.Conclusion. In tinnitus patients with normal pure-tone audiometry the high frequency audiometry provides useful additional information. The association between tinnitus laterality and asymmetry of the high frequency audiometry suggests a potential causal role for the high frequency hearing loss in tinnitus etiopathogenesis.

Abstract Purpose The study is concern with the distinguishing of the stimuli containing high frequency information with the frequency compression feature at the cortical level using the acoustic change complex (ACC) and the comparison of such with the ACC answers of individuals with normal hearing. Research Design This is a case–control study. Study Sample Thirty adults (21 males and nine females) with normal hearing, ranging in age between 16 and 63 years (mean: 36.7 ± 12.9 years) and 20 adults (16 males and four females) with hearing loss ranging in age between 16 and 70 years (mean:49.0 ± 19.8 years) have been included in this study. Data Collection and Analysis A total of 1,000 ms long stimulus containing 500 and 4,000 Hz tonal stimuli was used for ACC recording. The start frequency (SF) and compression ratio (CR) parameters of the hearing aids were programmed according to the default settings (SFd, CRd) in the device software, the optimal setting (SFo, CRo), and the extra compression (SFe, CRe) requirements and ACC has been recorded for each condition. Evaluation has been performed according to P1-N1-P2 wave complex and ACC complex wave latencies. Independent samples t-test was used to test the significance of the differences between the groups. Results In all individuals ACC has been observed. There was a significant difference between the wave latencies in normal hearing- and hearing-impaired groups. All wave latency averages of the individuals with hearing impairment were longer than the individuals with normal hearing. There were statistically significant differences between SFd-SFo, SFd-SFe, and SFo-SFe parameters. But there was no difference between CRd, CRo, and CRe in terms of CRs. Conclusion In order to discriminate high frequency information at the cortical level we should not rely on default settings of the SF and CR of the hearing aids. Optimal bandwidth must be adjusted without performing insufficient compression or over-compression. ACC can be used besides the real ear measurement for hearing aid fitting.
