An evaluation of various spatial audio rendering and presentation techniques to enhance active navigation with sensory augmentation
Journal of the Acoustical Society of America - Tập 154 Số 4_supplement - Trang A196-A196 - 2023

Poisson’s ratio of foamed aluminum determined by laser Doppler vibrometry
Journal of the Acoustical Society of America - Tập 91 Số 3 - Trang 1737-1744 - 1992
Pieter S. Dubbelday
Foamed aluminum is a promising candidate in hydroacoustics as a possible pressure-release material. Previously, the measurement of its dynamic shear modulus has been reported for various densities and pore sizes of the material, [Proc. IEEE, 1985 Ultrasonics Symp. 2, 1052–1055 (1985)]. In an attempt to complete the characterization of the material, its Young’s modulus and Poisson’s ratio w...... hiện toàn bộ

Frequencies Dominant in the Perception of the Pitch of Complex Sounds
Journal of the Acoustical Society of America - Tập 42 Số 1 - Trang 191-198 - 1967
R. J. Ritsma
This paper deals with measurements carried out with pulsive signals to determine the spectral region associated with dominant pitch perception. The stimulus consisted of the sum of (1) a low-frequency band of a unipolar pulse train with fundamental frequency f0 (or f0+Δf) and upper cutoff frequency fe and (2) a high-frequency band of a unipolar pulse train with fundamental frequency f0+Δf ...... hiện toàn bộ
Single-scattering approximations for coefficients in Biot’s equations of poroelasticity
Journal of the Acoustical Society of America - Tập 91 Số 2 - Trang 551-571 - 1992
James G. Berryman
Three single-scattering approximations for coefficients in Biot’s equations of poroelasticity are considered: the average T-matrix approximation (ATA), the coherent potential approximation (CPA), and the differential effective medium (DEM). The scattering coefficients used here are exact results obtained previously for scattering from a spherical inclusion of one Biot material imbedded in ...... hiện toàn bộ
Learning a novel phonological contrast depends on interactions between individual differences and training paradigm design
Journal of the Acoustical Society of America - Tập 130 Số 1 - Trang 461-472 - 2011
Tyler K. Perrachione, Jiyeon Lee, Louisa Y. Y. Ha, Patrick C. M. Wong
Studies evaluating phonological contrast learning typically investigate either the predictiveness of specific pretraining aptitude measures or the efficacy of different instructional paradigms. However, little research considers how these factors interact—whether different students learn better from different types of instruction—and what the psychological basis for any interaction might b...... hiện toàn bộ
Some effects of talker variability on spoken word recognition
Journal of the Acoustical Society of America - Tập 85 Số 1 - Trang 365-378 - 1989
John W. Mullennix, David B. Pisoni, Christopher S. Martin
The perceptual consequences of trial-to-trial changes in the voice of the talker on spoken word recognition were examined. The results from a series of experiments using perceptual identification and naming tasks demonstrated that perceptual performance decreases when the voice of the talker changes from trial to trial compared to performance when the voice on each trial remains the same. ...... hiện toàn bộ
Static, dynamic, and relational properties in vowel perception
Journal of the Acoustical Society of America - Tập 85 Số 5 - Trang 2088-2113 - 1989
Terrance M. Nearey
The present work reviews theories and empirical findings, including results from two new experiments, that bear on the perception of English vowels, with an emphasis on the comparison of data analytic ‘‘machine recognition’’ approaches with results from speech perception experiments. Two major sources of variability (viz., speaker differences and consonantal context effects) are addressed ...... hiện toàn bộ
Acoustic characteristics of American English vowels
Journal of the Acoustical Society of America - Tập 97 Số 5 - Trang 3099-3111 - 1995
James Hillenbrand, Laura Arlene Getty, Michael Clark, Kimberlee Wheeler
The purpose of this study was to replicate and extend the classic study of vowel acoustics by Peterson and Barney (PB) [J. Acoust. Soc. Am. 24, 175–184 (1952)]. Recordings were made of 45 men, 48 women, and 46 children producing the vowels /i,i,e,ε,æ,a,open‘‘oh’’,o,u,u,Λ,hook backward‘‘eh’’/ in h–V–d syllables. Formant contours for F1–F4 were measured from LPC spectra using a custom intera...... hiện toàn bộ
