No decrement at all (less than 10% decay 10 sec after the onset of a stimulus 10 dB above the reflex threshold) was present in a majority of the ears. Between 27 and 58% of the ears showed reflex decay depending on variations of different factors such as stimulus frequency, intensity of the stimulus, and the method to register the reflex. Reflex decay was more often seen at 1000 Hz than at 500 Hz stimulus frequency. Reflex decay was also more often seen 5 dB above the reflex threshold than at higher intensity levels.

In this study, LDL's and ART's were obtained for two groups of ten normal-hearing adult subjects and one group of ten adult subjects with bilateral sensorineural hearing losses. The procedure involved obtaining LDL's and ART's under earphones and under sound field conditions for four different acoustic stimuli: pure tones, warble tones, spondaic words, and speech spectrum noise. One group of normal-hearing subjects and the hard-of-hearing group of subjects were given \"too loud, uncomfortably loud, or annoyingly loud\" LDL instructions while a second group of normal hearing subjects were instructed to respond when a sound \"first starts to become uncomfortable.\" Results indicated that LDL's, irregardless of instructional pattern, were reported at consistently higher sound pressure levels than the ART's, for all groups of subjects. The magnitude of the differences between the LDL's and ART's varied according to LDL instrucitons, type of test stimulus, hearing sensitivity of the subjects (normal hearing or hard-of-hearing) and transducer used for stimulus presentation.

This paper reports the noise reduction characteristics measured for the conventional TDH-39 earphone mounted in the supra-aural MX-41/AR cushion and for the new TDH-50 Telephonics circumaural headset. The circumaural headset was found to produce an average of about 10 dB more noise attenuation than did a well-adjusted supra-aural device, and the circumaural headset provided much more consistent test-retest noise reduction characteristics.
