Evoked potentials: computer-automated threshold-tracking procedure using an objective detection criterion.

abstract：OBJECTIVES:Previous research suggests that young children have significant difficulty recognizing speech in the presence of background noise as compared with older children and adults. However, limited research exists that examines the developmental effects of speech recognition in noise in separate age groups of young...

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...
