The present study evaluated whether similar weights are observed for speech-in-speech recognition that relies on access to vowels or consonants, given differences in the distributions of cues required for vowel and consonant recognition. Spectral weights were estimated by filtering stimuli into 1-octave-wide bands, dispersing those bands on the horizontal plane, and assessing the association between each band's position and participants' responses. Data were obtained for two tasks: 1) localization of the target relative to the masker (left vs. right), and 2) closed-set word recognition, where response alternatives differed either with respect to the initial consonant, vowel, or final consonant. As observed previously, weights for both tasks peaked at 0.5-1 kHz for all three stimulus sets. This result is consistent with the idea that the spatial cues supporting spatial release from masking are similar regardless of the frequency regions containing speech cues required for correct recognition of the target.","PeriodicalId":88302,"journal":{"name":"Proceedings of meetings on acoustics.

The resulting contact pressure is often considered to play an important role in vocal fold injury, and has been the focus of many experimental studies. In this study, vocal fold contact pattern and contact pressure during phonation were numerically investigated. The results show that vocal fold contact in general occurs within a horizontal strip on the medial surface, first appearing at the inferior medial surface and propagating upward. Because of the localized and travelling nature of vocal fold contact, sensors of a finite size may significantly underestimate the peak vocal fold contact pressure, particularly for vocal folds of low transverse stiffness. This underestimation also makes it difficult to identify the contact pressure peak in the intraglottal pressure waveform. These results showed that the vocal fold contact pressure reported in previous experimental studies may have significantly underestimated the actual values. It is recommended that contact pressure sensors with a diameter no greater than 0.4 mm are used in future experiments to ensure adequate accuracy in measuring the peak vocal fold contact pressure during phonation.","PeriodicalId":88302,"journal":{"name":"Proceedings of meetings on acoustics.

Lyons","doi":"10.1121/2.0001647","DOIUrl":"https://doi.org/10.1121/2.0001647","url":null,"abstract":"When focused to a small spot size in air, a sufficiently energetic laser pulse initiates a rapidly expanding plasma. After a delay, a shockwave detaches from the plasma boundary and propagates. General features of the shockwaves can be deduced from condenser microphone measurements. However, the minimum range is limited by damage thresholds, and the presence of the microphone introduces a number of measurement artifacts. Distortion of the signal is caused by diffraction around the sensor, and the limited bandwidth does not allow rise times to be correctly quantified. In contrast, optical interferometry is a nonintrusive diagnostic for quantifying shockwave characteristics. In this study, a Nd:YAG laser is focused through a converging lens in order to generate laser-induced shockwaves. By using a variable attenuator, four laser energy outputs are examined: 25, 50, 75, and 100% of the maximum energy transmission. Heterodyne Mach–Zehnder interferometer measurements are made from 10 mm to 200 mm from the focal point of the lens. Virtual velocity signals, proportional to the time derivative of optical phase differences, are used to estimate density and pressure time histories, along with peak pressure as a function of distance.","PeriodicalId":88302,"journal":{"name":"Proceedings of meetings on acoustics.
