AbstractObjective:For various medico-legal and financial reasons, some patients may clinically demonstrate an exaggerated hearing loss that varies in degree, nature and laterality. The purpose of this study was to evaluate whether multi-channel auditory steady-state response measurement can be used as an objective test of auditory thresholds in adults with sensorineural hearing loss.Study design and setting:This was a prospective, comparative, experimental research design study conducted in an academic medical centre. From January to June 2007, 142 subjects (284 ears) with varying degrees of sensorineural hearing loss were included. Four commonly used frequencies (500, 1000, 2000 and 4000 Hz) were evaluated. Both pure tone thresholds and multi-channel auditory steady-state response thresholds were obtained for each ear in all subjects. The correlation of auditory steady-state response thresholds and pure tone thresholds was assessed. The time taken for multi-channel auditory steady-state response testing was also recorded.Results:Results for multi-channel auditory steady-state response thresholds and pure tone thresholds were compared for each test frequency. A difference of less than 15 dB was found in 71 per cent of patients, while a difference of less than 20 dB was found in 83 per cent. Correlation between auditory steady-state response thresholds and pure tone thresholds, expressed as the correlation coefficient (r), was 0.89, 0.95, 0.96 and 0.97 at 500, 1000, 2000 and 4000 Hz, respectively. The strength of the relationship between auditory steady-state response thresholds and pure tone thresholds increased with increasing frequency and increasing degree of hearing loss. The recorded auditory steady-state response thresholds were used to calculate regression lines predicting pure tone threshold results. The mean estimated pure tone thresholds calculated from these regression lines were all within 10 dB of the actual recorded pure tone thresholds. The average multi-channel auditory steady-state response test duration was 42 minutes per patient.Conclusion:Measurement of multi-channel auditory steady-state response could be a powerful, convenient electro-physiological examination with which to objectively certify clinical hearing impairment in adults.

Auditory Steady State Response

Background: Auditory steady-state response (ASSR) is a test for the estimation of auditory thresholds. It is used in infants, children, and adults. This case report presented unusual ASSR results in an elderly person. The Case: Pure tone and speech audiometry, tympanometry and acoustic reflexes showed a moderate sensorineural hearing loss in both ears. However, the patient did not respond in the ASSR test to different carrier frequencies with frequency modulations of 40 and 80 Hz. Conclusion: To date, the results of the different effects of the aging process obtained from ASSR responses have been reported. However, the absence of any response in the ASSR test has never been reported. The patient in this case report may have these results because of a neural deficit.

The auditory steady state response (ASSR) has recently gained attention with respect to estimates of hearing sensitivity and configuration of hearing loss. The present investigation compared behavioral thresholds to estimated ASSR thresholds in subjects with confirmed CANS lesions to determine if this population can be accurately evaluated with ASSR techniques. Comparisons were made between the experimental group and a normal control group matched for age and hearing sensitivity. ASSR thresholds were obtained for the carrier frequencies of 500 and 2000 Hz with a 46 Hz modulation rate and compared to behavioral thresholds. Within and between group comparisons were made. The control group demonstrated strong correlation between their behavioral and estimated ASSR thresholds which significantly contrasted the neurological group. Additionally, individuals with neurological impairment of the CANS exhibited elevated thresholds that were on average 24 dB greater at 2000 Hz than their behavioral thresholds. These results suggest that individuals with neurological insult may appear as hearing impaired or having greater hearing loss than is actually present. As a result, the ASSR may demonstrate the potential to assist in the detection of CANS dysfunction. Las respuestas auditivas de estado estable (ASSR) han ganado atención recientemente con respecto a la estimación de la sensibilidad auditiva y la configuración de la pérdida auditiva. La presente investigación comparó los umbrales conductuales con umbrales estimados por ASSR en sujetos con lesiones CANS confirmadas para determinar si esta población podía ser evaluada con exactitud por medio de técnicas de ASSR. Las comparaciones se realizaron entre el grupo experimental y un grupo control normal ordenados por edad y sensibilidad auditiva. Los umbrales de los ASSR se obtuvieron por medio de frecuencias portadoras de 500 y 2000 Hz, con una tasa de modulación de 46 Hz y se compararon con los umbrales conductuales. Se realizaron comparaciones entre los grupos y dentro de un mismo grupo. El grupo de control mostró una fuerte correlación entre sus umbrales conductuales y los estimados por ASSR, que contrastó significativamente con el grupo neurológico. Adicionalmente, los individuos con un trastorno neurológico de CANS exhibieron umbrales elevados que fueron en promedio 24 dB más alto en 2000 Hz que sus umbrales conductuales. Estos resultados sugieren que los individuos con alteraciones neurológicas pueden lucir como alterados auditivamente o teniendo una pérdida auditiva mayor de la realidad. Como resultados, los ASSR puede demostrar el potencial para ayudar en la detección de la disfunción por CANS.
