摘要:

Interval histograms are computed from a threshold‐crossing model for auditory‐nerve activity. The calculations do not resemble real nerve histograms measured for combination‐tone frequencies. It appears unlikely that a threshold‐crossing model can explain the synchrony of auditory‐nerve impulses to combination tones.

摘要:

Six subjects with an acoustic reflex and six subjects without an acoustic reflex were exposed on separate occasions to a 710‐Hz pure tone and to a18‐octband noise with an upper cutoff frequency of 710 Hz. Both exposures were 10 min at 110 dB sound‐pressure level. Temporary threshold shift (TTS) was measured at 1000 Hz. For the subjects with an acoustic reflex, the pure‐tone exposure produced 10 dB more TTS2than the noise exposure. However, for the subjects without an acoustic reflex, the pure‐tone exposure and the noise exposure produced the same amounts of TTS. These results support the hypothesis that low‐frequency pure tones produce more TTS than low‐frequency bands of noise because of the differential effects of the acoustic reflex in responding to these two types of sounds.

摘要:

Comparison of the speech waveform with ultrasonic signals from the larynx recorded simultaneously gives information about the temporal properties of the glottal source. Physiological information obtained with this technique corroborates the time relationships between speech output and excitation waveform found with inverse filtering.
