Estimates of compression at low and high frequencies using masking additivity in normal and impaired ears.
Auditory compression was estimated at 250 and 4000 Hz by using the additivity of forward masking technique, which measures the effects on signal threshold of combining two temporally nonoverlapping forward maskers. The increase in threshold in the combined-masker condition compared to the individual-masker conditions can be used to estimate compression. The signal was a 250 or 4000 Hz tone burs...
متن کاملA new approach to comparing binaural masking level differences at low and high frequencies.
A new experimental technique for studying binaural processing at high frequencies is introduced. Binaural masking level differences (BMLDs) for the conditions N0S pi and N pi S0 were measured for a tonal signal in narrow-band noise at 125, 250, and 4000 Hz. In addition, "transposed" stimuli were generated, which were centered at 4000 Hz, but were designed to preserve within the envelope the tem...
متن کاملOn- and off-frequency compression estimated using a new version of the additivity of forward masking technique.
On- and off-frequency compression at the 4000- and 8000-Hz cochlear places were estimated using a new version of the additivity of forward masking (AFM) technique, that measures the effects of combining two non-overlapping forward maskers. Instead of measuring signal thresholds to estimate compression of the signal as in the original AFM technique, the decrease in masker threshold in the combin...
متن کاملForward-Masking Recovery and the Assumptions of the Temporal Masking Curve Method of Inferring Cochlear Compression
The temporal masking curve (TMC) method is a behavioral technique for inferring human cochlear compression. The method relies on the assumptions that in the absence of compression, forward-masking recovery is independent of masker level and probe frequency. The present study aimed at testing the validity of these assumptions. Masking recovery was investigated for eight listeners with sensorineu...
متن کاملEstimates of Temporal Resolution at Low and High Spectral Frequencies
Abstmcti Amplitud&modtiation dektion w measured as a fmction of modulation frequency for narrowband noise carriers and the resulting temporal modulation transfer functions were used to characterize temporal acuity over a range of audio frequencies hm 800 to 12800 W. Systematicmanipulations of carrier upper+utoff frequency produced estimates of temporal acuity that did not vary from 800 to 12800...
