AbstractTinnitus is a symptom of many disorders affecting the auditory system. While Impedance Audiometry provides no specific etiologic information about tinnitus, it is a useful diagnostic tool to localize various types of auditory dys-function. This paper sketches usefulness of impedance testing in diagnosis of retro-cochlear lesions, in otosclerosis and in objective tinnitus.

The electronic probe provides a simple means to detect eustachian tube patency, and can be used as a sensitive probe of objective tinnitus. The basic unit consists of a battery-operated, electronic amplifier connected by 18-in leads to a sensitive microphone and to a small speaker (Fig 1). These transducers are each connected to rubber nipples of the type used for impedance audiometry (Fig 2).

Auditory Brainstem Response Audiometry

The purpose of this paper is to describe the audiologic techniques currently used at the Otologic Medical Group, Inc. Auditory threshold in children is determined by a combination of behavioral and objective audiometric techniques. When behavioral techniques fail, auditory brainstem response audiometry combined with impedance audiometry gives a good estimate of hearing thresholds. Impedance audiometry is a valuable addition to the diagnosis of cochlear otosclerosis. This technique is also of benefit in the neurotologic evaluation. Auditory brainstem response audiometry is the most accurate method of detecting an acoustic tumor. We no longer use SISI, tone decay, or Bekesy tests. The newer audiometric studies have greatly improved our evaluation of the auditory system.

Language Analysis

Elicited imitation tasks are frequently used as a diagnostic tool in evaluating children with communication handicaps. This article presents a scoring procedure that can be used to obtain an in-depth descriptive analysis of responses produced on elicited imitation tasks. The Elicited Language Analysis Procedure makes it possible to systematically evaluate responses in terms of both their syntactic and semantic relationships to the stimulus sentences presented by the examiner. Response quality measures are also included in the analysis procedure.

Purpose The effects of neurological diseases on the auditory system have been a notable issue for investigators because the auditory pathway is closely associated with neural systems. The purposes of this study are to evaluate the efferent auditory system function and hearing quality in Parkinson's disease (PD) and to compare the findings with age-matched individuals without PD to present a perspective on aging. Method The study included 35 individuals with PD (mean age of 48.50 ± 8.00 years) and 35 normal-hearing peers (mean age of 49 ± 10 years). The following tests were administered for all participants: the first section of the Speech, Spatial and Qualities of Hearing Scale; pure-tone audiometry, speech audiometry, tympanometry, and acoustic reflexes; and distortion product otoacoustic emissions (DPOAEs) and contralateral suppression of DPOAEs. SPSS Version 25 was used for statistical analyses, and values of p < .05 were considered statistically significant. Results There were no statistically significant differences in the pure-tone audiometry thresholds and DPOAE responses between the individuals with PD and their normal-hearing peers ( p = .732). However, statistically significant differences were found between the groups in suppression levels of DPOAEs and hearing quality ( p < .05). In addition, a statistically significant and positive correlation was found between the amount of suppression at some frequencies and the Speech, Spatial and Qualities of Hearing Scale scores. Conclusions This study indicates that medial olivocochlear efferent system function and the hearing quality of individuals with PD were affected adversely due to the results of PD pathophysiology on the hearing system. For optimal intervention and follow-up, tasks related to hearing quality in daily life can also be added to therapies for PD.

Computer synthesized vowels of 50- and 300-ms duration were presented to normal-hearing listeners at a moderate and high sound pressure level (SPL). Presentation at the high SPL resulted in poor recognition accuracy for vowels of a duration (50 ms) shorter than the latency of the acoustic stapedial reflex. Presentation level had no effect on recognition accuracy for vowels of sufficient duration (300 ms) to elicit the reflex. The poor recognition accuracy for the brief, high intensity vowels was significantly improved when the reflex was preactivated. These results demonstrate the importance of the acoustic reflex in extending the dynamic range of the auditory system for speech recognition.
