Wireless synchronization of the digital signal processing (DSP) features between two hearing aids in a bilateral hearing aid fitting is a fairly new technology. This technology is expected to preserve the differences in time and intensity between the two ears by co-ordinating the bilateral DSP features such as multichannel compression, noise reduction, and(More)
This study examined the possibility that age-related differences in speech discrimination abilities may reflect individual differences in the amount of masking and in the rate of growth of on- and off-frequency masking. Young (mean age = 26 years) and older (mean age = 60 years) adult listeners were selected, all of whom had hearing thresholds equal to or(More)
Recent studies of the relation between loudness and intensity difference limens (DLs) suggest that, if two tones of the same frequency are equally loud, they will have equal relative DLs [R. S. Schlauch and C.C. Wier, J. Speech Hear. Res. 30, 13-20 (1987); J.J. Zwislocki and H.N. Jordan, J. Acoust. Soc. Am. 79, 772-780 (1986)]. To test this hypothesis,(More)
Voiced (/ba/ or /da/) and voiceless (/pa/ or /ta/) consonants seem to affect different auditory system loci. On a voice-onset-time continuum (/ba/ to /pa/ or /da/ to /ta/) the selective adaptation effects produced by voiceless consonants are largely ear-independent and endure over delays of at least 1 min. However, voiced adapters produce selective(More)
A sample of 209 adults ranging from 20 to 79 years of age were studied to measure speech communication profiles as a function of age in persons who did not identify themselves as hearing impaired. The study was conducted in order to evaluate age-related speech percepton abilities and ccammmication profiles in a population who do not present for hearing(More)
