Pure-tone auditory threshold in school children

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.

The Voice

The purpose of this study was to determine the extent to which other communicative disorders coexist with voice disorders in school children. The authors randomly selected two voice deviant groups and a control group from a database of nearly 39,000 school children in grades 1–12. Hoarseness was the most commonly occurring voice disorder in both groups. The majority of voice disordered children had coexisting articulation deviations. In addition, the voice disordered samples differed significantly from controls on two language measures and mean pure-tone hearing thresholds. This study supports other research indicating that different communication disorders frequently coexist.

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.
