To evaluate the medicolegal relevance of middle latency responses for objectively approximating frequency-specific hearing levels in subjects with occupational hearing loss, we compared the middle latency response with the cortical response in 22 reliable subjects who had noise-induced hearing loss and were submitting claims for compensation and 21 subjects who had noise-induced hearing loss bu...

BACKGROUND/AIM A more recent method, the auditory steady-state response (ASSR), has become more and more important test method due to difference that was found in previous investigations between hearing thresholds determined by the ASSR and the pure-tone audiometry (PTA). The aim of this study was to evaluate the reliability of the ASSR in determining the frequency specific hearing thresholds b...

UNLABELLED Brainstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus. AIM To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right). STUDY DESIGN A retrospective study. MATERIALS ...

UNLABELLED Illicit drugs are known for their deleterious effects upon the central nervous system and more specifically for how they adversely affect hearing. OBJECTIVE This study aims to analyze and compare the hearing complaints and the results of brainstem evoked response audiometry (BERA) of former drug user support group goers. METHODS This is a cross-sectional non-experimental descript...

Cortical evoked response audiometry is adequate for approximating hearing threshold levels with frequency specificity when the psychoacoustic responses lack reliability and reproducibility (compensation claim). It is well-known that control of wakefulness is essential for the reliability of slow vertex responses (SVR). Therefore, sedative, hypnotic, and neuroleptic drugs are supposed to have po...
