Audiometric asymmetry and tinnitus laterality
https://pubmed.ncbi.nlm.nih.gov/22447577/
An optimal audiometric asymmetry index to predict tinnitus laterality is one whereby 15 dB is the minimum aITD of two adjoining frequencies, inclusive of the maximal ITD. Tinnitus laterality dependency on magnitude of interaural asymmetry may inform design and interpretation of neuroimaging studies. …

Audiometry in the family medicine clinic setting is a relatively simple procedure that can be interpreted by a trained health care professional. Pure-tone testing presents tones across the speech ...

Audiometry has been and still is the best initial screening test for diagnosing acoustic neuromas. (Only 5% of acoustic neuromas have a normal auditory evaluation.) Pure tone and speech audiometry should be performed. Test results show an asymmetrical sensorineural hearing loss, usually more prominent in the higher frequencies (Fig. 165-1). Typically the speech …

Quick and consistent localization of the sound source suggests balanced or nearly balanced hearing between the 2 ears, whereas asymmetric hearing thresholds result in impaired localization. A tablet-based automated audiometer has been developed as a method for threshold hearing assessment outside of conventional sound booths ( 31 ).
Asymmetric hearing loss: rule 3,000 for screening ...
https://pubmed.ncbi.nlm.nih.gov/19395982/
The ASNHL at 3,000 Hz was the most representative value of all the frequencies and for the SDS asymmetry. Interaural difference of 15 dB or more at 3,000 Hz is sufficient to consider hearing loss as asymmetric. When the cutoff for a positive test was placed at 50% probability, the receiver operating characteristic curve shows a sensitivity of 73%.

Brief deviations of interaural correlation (IAC) can provide valuable cues for detection, segregation and localization of acoustic signals. This study investigated the processing of such "binaural gaps" in continuously running noise (100-2000 Hz), in comparison to silent "monaural gaps", by measuring late auditory evoked potentials (LAEPs) and perceptual thresholds with novel, …
Asymmetry in noise-induced hearing loss: evaluation of …
https://pubmed.ncbi.nlm.nih.gov/24804714/
Competing theories exist about why asymmetry is observed in noise-induced hearing loss (NIHL). We evaluated these theories using a cohort of young workers studied over 16 years. The study aim was to describe and evaluate patterns of hearing loss and asymmetry by gender, agricultural exposure and gun …

This index may span from −1 to 1. When this index approaches zero, it means that the sound localization performance is similar across the good- vs. poor-hearing ear sides. When the good-hearing side markedly outperformed the poor-hearing side, the AI was approximately 1. The SSD group was tested via the intact ear. In the NC group, a simulation experiment was conducted to …
