“the sound of speech” and “the sound of song”.The Anti-Japanese War lyrics emphasize musical rhythm and the harmony of rhymed words;use the collocation of content words and function words,focusing on light and stressed syllables,ensuring that the recitation and singing rhythms align.These ...
They found that these speakers showed an increase in sound pressure level in Lombard speech compared to plain speech, although the amount of increase depended on the combination of the language they spoke and the task. Cai, Yin, and Zhang (2020) examined Chinese-English late bilinguals, finding...
mandatory to provide an external digital sound programme access port at 384 kbit/s. 1.3Two methods of encoding have been specified by the CMTT 1 and these form the basis for this Recommendation. 2Transmission performance The transmission performance per encoder/decoder pair shall be such that the...
A comparison is made of methods of measuring the acoustic characteristics of sound-absorbing materials in an acoustic interferometer. The methods considered are the standing-wave, two-microphone, least-squares, three-points, and nonlinear regression ones. The advantages and shortcomings of each method ...
Finally, we present in the last section how it can be used to predict the changes of the driving point mobility, and possibly of the sound radiation in the treble range, resulting from structural m...Ege K,Boutillon X.Vibrational and acoustical characteristics of the piano soundboard.20th ...

A previous study (Westbury, Hashi, & Lindstrom (1998), Speech Communication 26, 203–226) found no relation between articulatory postures and formant frequencies at phonation onset of words beginning with the sound. The present study examined acoustic–articulatory relations in time-varying acoustic ...
The human ear has auditory sensitivity characteristics such that sounds in a low frequency range and a high frequency range become difficult to hear as the sound pressure level is reduced, as indicated by Fletcher Manson curves of FIG. 15. In the conventional controllers, however, only compensatio...
