Effects of an adaptive filter hearing aid on speech recognition in noise by hearing-impaired subjects.

abstract：:The purpose of this report is to describe the speech production of children participating in the Food and Drug Administration's approved clinical trials for the Nucleus multichannel cochlear implant. A significant increase in the ability to imitate nonsegmental aspects of speech was noted after using the implant; howe...

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...
