Bilateral and unilateral cochlear implant users compared on speech perception in noise.

abstract：:The use of auditory brain stem response (ABR) represents a new dimension in auditory and neurological pediatric assessment. Because the ABR may be altered by stimulus and procedural variables, the lack of an established standard has reduced its clinical efficiency. This paper describes a suggested ABR protocol for inf...

abstract：OBJECTIVES:Although directional microphones on a hearing aid provide a signal-to-noise ratio benefit in a noisy background, the amount of benefit is dependent on how close the signal of interest is to the front of the user. It is assumed that when the signal of interest is off-axis, users can reorient themselves to the...
