Speech perception and growth of masking in younger and older adults

Margaret F. Cheesman, Jennifer C. Armitage, Kimberley Marshall

Speech discrimination abilities and growth of masking in the 1000-Hz region were measured in younger and older listeners. All listeners had hearing thresholds equal to or better than 30 dB HL at audiometric frequencies < 2000 Hz and equal or better than 40 dB HL at audiometric frequencies from 3000 to 6000 Hz. In the first experiment, listeners were tested on a modified version [1] of the distinctive feature difference test [2] presented (a) in quiet, (b) in wide band noise, (c) high-pass filtered at 2000 Hz, and (d) low-pass filtered at 1000 Hz. Despite their good hearing thresholds, the older listeners made significantly more errors in all four test conditions and were more adversely affected by the degraded listening conditions than the younger listeners. In a second experiment, masked thresholds for signal frequencies of 750, 1000, and 1500 Hz in the presence of a 1/3-octave band of noise centred at 1000 Hz were obtained with four noise levels from 50 to 80 dB SPL. The older listeners had higher masked thresholds, however the slope of the growth of masking functions did not differ with age.
