Retest Session

This study investigated the validity and reliability of Bekesy audiometry with preschool-age children. Sixty preschool children, ages 3, 4, and 5, were chosen such that 20 children were in each of the three age groups. There were an equal number of male and female subjects in each group, and all had intelligence quotients of 90 or higher. Each subject was given a conventional pure-tone hearing evaluation, followed by a hearing test administered with a Bekesy audiometer. A retest session was conducted one week later. The results indicate that five-year-old children, when properly conditioned, can be tested with Bekesy audiometry and produce valid, reliable auditory threshold tracings. Some four-year-old children will trace a Bekesy audiometric threshold that is valid, whereas, other four-year-old children trace thresholds that are not a true representation of their actual auditory threshold. Typically, three-year-old children, as presently conditioned, are not candidates for Bekesy audiometry.

Over Time

Hearing threshold has been measured in a group of patients following cochlear implantation with a Clarion® device for the last eight years. The patients had received either a pre-curved carrier or the Hi-Focus I plus Electrode Positioner System (EPS). The assessment was carried out within the first post-operative week as well as at a later stage, between six and 87 months, post-operatively. Residual hearing thresholds were still measurable early after surgery in 24.5 per cent of the patients, without differences between the two different Clarion® models. However, the number of subjects with measurable hearing dropped to 16.3 per cent as observed when hearing was measured at a later stage, with an equal distribution between the two groups of patients. From this study it has been possible to observe that only a limited number of patients maintain residual hearing after Clarion® cochlear implantation, and that this tends to decrease further over time. Nevertheless, the performance of these patients for speech tests did not appear to be affected by deterioration of the pure-tone auditory threshold.

Contingent Response

Twenty-four normal-hearing adults were conditioned to associate a flash of light (unconditioned stimulus) with a pure tone (conditioned stimulus). The contingent response was used to estimate auditory threshold for 500, 1000, and 2000 Hz. Results showed that 23 of the 24 subjects were conditioned to form the tone-light association, the majority within 10 trials. Conditioned EEG responses varied in form, amplitude, and latency within and among individuals, and were without hemispheric predominance. The evoked EEG response habituated rapidly, whereas the conditioned EEG response was maintained throughout the procedure and transferred readily among the test frequencies. Auditory threshold estimated by this method was within 5 dB of voluntary threshold for at least one of the test frequencies for all 23 of the conditioned subjects.
