Active clinical trials for "Hearing Loss"

The purpose of this study is to evaluate the benefit of bimodal hearing and bilateral cochlear implant hearing in comparison to unilateral cochlear implant hearing in the perception of speech intonation.

Over the last few decades, the classical two-stage surgical procedure for inserting bone-anchored hearing implants (BAHIs) has been modified in adults into a single-stage procedure. This approach has several advantages since it avoids a second surgical procedure. The single-stage approach is proven to be safe and feasible in adults and is nowadays referred to as the standard surgical technique in adults. Despite favorable outcomes and advantages of the single-stage surgery, most Ear Nose Throat (ENT) surgeons still perform two-stage surgery when inserting BAHI in the pediatric population. Therefore, the aim of this study is to compare implant loss between single-stage BAHI surgery and two-stage BAHI surgery in children aged 4 to 9 years.

We study audiometric parameters including Transient Otoacoustic emissions, pure-tone audiometry for air- and bone-conduction, and spondaic speech recognition thresholds for air- and bone conduction in a pre- and postoperative situation in patients due for surgery for tympanic membrane perforations and otosclerosis. The hypotheses are that the precision of the preoperative assessment may be increased, and our knowledge about the effect on the inner ear by middle ear surgery may be increased.

The aim of the research: Investigate the association of auditory evoked brainstem response characteristics with salivary cortisone concentrations in noise-exposed workers. Purpose of the research: Investigate the magnitude of the amplitudes and latencies of auditory brainstem responses. Investigate the concentration of cortisone in saliva. To investigate the correlation of the characteristics of auditory evoked brainstem potentials with the age of the subjects or the length of work in noise. Investigate the association of salivary cortisone concentration with subjects' age or length of work in noise. Investigate the prevalence of mild, moderate and severe hearing impairment in the 19-35 age group. Investigate the relationship of hearing threshold shift with the age of the subjects or the length of work in noise. To investigate the difference in the characteristics of auditory evoked brainstem potentials and the difference in salivary cortisone concentration between subjects with a bilaterally normal hearing threshold (≤25 dB) at high frequencies and subjects with unilaterally or bilaterally increased hearing threshold (> 25 dB) at high frequencies . Investigate the perceived stress and psychosocial risk factors in the workplace and their relationship to salivary cortisone concentrations. Research Hypothesis: There is an association between the characteristics of auditory evoked brainstem response and salivary cortisone concentrations in noise-exposed workers. Research participants Inclusion criteria: male and female ages 19-35 exposure to noise level ≥ 85 dB (A) per week at the workplace work in noise from 1 to 16 years workplace not involving exposure to carbon disulfide or a mixture of organic solvents that have toxic effects on the ear (toluene, xylene and styrene) unilaterally or bilaterally normal otoscopic findings unilaterally or bilaterally tympanogram: peak pressure value ± 50 daPa at 226 Hz with eardrum mobility of 0.3 to 1.3 mL Exclusion criteria: information about an earlier sudden hearing loss information on chronic middle ear inflammation information on ear surgery (except placement of ventilation tubes in the eardrum) information on dizziness associated with hearing loss and noise information on insomnia current use of oral corticosteroids bilaterally found air-bone gap greater than 15 dB

This observational study aims to validate the use of a tablet based audiometer to provide an accurate, efficient, and cost-effective means for diagnosis of hearing conditions in controlled and uncontrolled environments in adult and elderly populations.

This study aims to explore the determinants of cognitive impairment among Indonesian geriatrics in an Old Age Home.

This trial is a pilot study to assess the feasibility of using Electrocochleography recorded from a cochlear implant intra-operatively in real time to monitor the progress of its insertion. Correlation between: Observed changes in this signal during surgery and residual hearing loss post-operatively and Recordings of this signal post-operatively and actual pure tone audiometry results will also be assessed.

Hearing impairment is common in older adults, and recent research points to associations between hearing impairment and balance/mobility. The association may be due to more attentional resources being used to compensate for the sensory loss, with less resources available for maintaining balance. The aim of this projects is therefore to investigate whether an exercise program with focus on motor-cognitive tasks is feasible for older adults with hearing impairment. The study is meant as a proof-of-concept study, where trialling will be evaluated, and results will be used to inform the design of a larger and adequately powered study.

In this clinical trial, an un-controlled, repeated measures open design with within-subject comparison will be used to evaluate the effect of the device under investigation on sound perception. This design was shown to be successful in previous studies for the evaluation of sound coding strategies. Furthermore, a within-subject comparison decreases the variance in the results allowing for fewer subjects when the population using the investigational device is not large in general.
