Evidence against the influence of aging on distortion-product otoacoustic emissions.

abstract：BACKGROUND:Children with auditory processing disorders (APD) are described to have a signal-to-noise ratio (SNR) difficulty. Frequency-modulated (FM) systems have been reported to improve this situation. Yet the use of personal amplification that may be more portable has not been attempted. PURPOSE:To determine whethe...
