Speech Identification

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.

Threshold Elevation

The role that sensorineural hearing loss plays in the speech-recognition difficulties of the hearing-impaired elderly is examined. One approach to this issue was to make between-group comparisons of performance for three groups of subjects: (a) young normal-hearing adults; (b) elderly hearing-impaired adults; and (c) young normal-hearing adults with simulated sensorineural hearing loss equivalent to that of the elderly subjects produced by a spectrally shaped masking noise. Another approach to this issue employed correlational analyses to examine the relation between audibility and speech recognition within the group of elderly hearing-impaired subjects. An additional approach was pursued in which an acoustical index incorporating adjustments for threshold elevation was used to examine the role audibility played in the speech-recognition performance of the hearing-impaired elderly. A wide range of listening conditions was sampled in this experiment. The conclusion was that the primary determiner of speech-recognition performance in the elderly hearing-impaired subjects was their threshold elevation.

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.
