OBJECTIVE The timely diagnosis of hearing loss in the pediatric population has significant implications for a child's development. However, audiological evaluation in this population poses unique challenges due to difficulties with patient cooperation. Though specialized adaptations exist (such as conditioned play audiometry), these methods can be time consuming and costly. The objective of thi...

BACKGROUND Hearing screening tests based on pure-tone audiometry may be conducted on mobile devices, provided that the devices are specially calibrated for the purpose. Calibration consists of determining the reference sound level and can be performed in relation to the hearing threshold of normal-hearing persons. In the case of devices provided by the manufacturer, together with bundled headph...

OBJECTIVE To compare the efficacy and feasibility of teleaudiometry with that of sweep audiometry in elementary school children, using pure-tone audiometry as the gold standard. METHODS A total of 243 students with a mean age of 8.3 years participated in the study. Of these, 118 were boys, and 125 were girls. The following procedures were performed: teleaudiometry screening with software that...

An adaptive, maximum likelihood (ML) procedure was assessed as an automated tool for estimating audiometric pure-tone thresholds in the clinic under computer control. Pure-tone air-conduction thresholds were measured from 101 workmen who received annual hearing rechecks as part of their employee hearing conservation program. A pure-tone threshold was measured bilaterally for each of the standar...

OBJECTIVE To evaluate the usefulness of pure-tone audiometry, tympanometry, and liquid and acoustic reflex (AR) tests in the differential diagnosis of ossicular fixation and discontinuity. DESIGN A prospective clinical trial. SETTING Tertiary referral center. PATIENTS Thirty-nine patients (46 ears) undergoing operations at University of Tsukuba Hospital, Tsukuba, Japan, from 1990 through ...

BACKGROUND Audiological evaluation of parents of individuals with autosomal recessive hearing loss. AIM To study the audiological profile of parents of individuals with autosomal recessive hearing loss, inferred by family history or by molecular tests that detected heterozygous mutations in the GJB2 gene. This gene codes Connexin 26. METHOD Participants were 36 subjects, ranging between 30 ...

OBJECTIVE To investigate whether the residual hearing of severely hearing-impaired children and adults could be preserved using the soft surgery approach. PATIENTS AND METHODS This project employed a prospective study design. All testing and surgery took place in the Institute of Physiology and Pathology of Hearing, Warsaw, Poland. Twenty-six patients (7 children and 19 post-lingually deafene...
