Chapter 7 : Evoked potential audiometry
When conventional behavioural audiometry is difficult or impossible, or when its results are inaccurate or suspect, there is a need for more objective hearing tests. Candidates for such tests include young infants, uncooperative, hyperactive, or neurologically impaired children, and those suspected of non-organic hearing loss. The usual goal is to approximate pure tone thresholds, using some me...
متن کاملBrain stem evoked response audiometry A Review
Brain stem evoked response audiometry (BERA) is a useful objective assessement of hearing. Major advantage of this procedure is its ability to test even infants in whom conventional audiometry may not be useful. This investigation can be used as a screening test for deafness in high risk infants. Early diagnosis and rehabilitation will reduce disability in these children. This article attempts ...
متن کاملIn-Air Evoked Potential Audiometry of Grey Seals (Halichoerus grypus) from the North and Baltic Seas
In-air anthropogenic sound has the potential to affect grey seal (Halichoerus grypus) behaviour and interfere with acoustic communication. In this study, a new method was used to deliver acoustic signals to grey seals as part of an in-air hearing assessment. Using in-ear headphones with adapted ear inserts allowed for the measurement of auditory brainstem responses (ABR) on sedated grey seals e...
متن کاملCortical evoked response audiometry thresholds and neuroleptic, sedative, hypnotic drugs.
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...
متن کاملBrainstem evoked response audiometry in normal hearing subjects.
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 ...
