acoustic theory

[ə′küs·tik ′thē·ə·rē]
(aerospace engineering)
The linearized small-disturbance theory used to predict the approximate airflow past an airfoil when the disturbance velocities caused by the flow are small compared to the flight speed and to the speed of sound.

This textbook introduces the fundamentals of speech and hearing science, covering breathing, laryngeal function, velopharyngeal-nasal function, and pharyngeal function of speech production; acoustics; the acoustic theory of vowel production; the theory of consonant acoustics; speech acoustics measurement and analysis; acoustic phonetics data; speech perception; neural structures and mechanisms for speech, language, and hearing; and swallowing.
In accordance with underwater acoustic theory, this layer is relatively conducive to acoustic signal transmission.
The fractal acoustic theory is also applicable to other materials having a microstructure similar to the PFMMs.
The acoustic theory of speech is usually applied to voiced sounds in the pitch range of speech, where the harmonics are dense enough to supply sound for any formant.
Those measurements, and the acoustic theory we developed to interpret the data, provided the foundation for this critically important study that will be relevant to the seabed in somewhat deeper waters.
He added: "The course was great, the acoustic theory in the first year opened my mind to the way hearing works, and the synthesis and electro acoustic composition modules were a good basis for electronic creativity."
The authors would like to thank the following Professors: Qian Cheng (Institute of Acoustics, Tongji University, Shanghai, China) for ultrasound parameters calibration and Wen-de Shou (Shanghai Institute of Ultrasound in Medicine, Shanghai, China) for acoustic theory consultation.
"I don't think you'll find many archaeologists who know about Stonehenge giving this particular acoustic theory a lot of time," he added.
This case report presents acoustic theory, along with test procedures, results, and conclusions.
Henderson developed a hypothesis that one solution could be the designing of "filters" into the piping systems based on acoustic theory. Arkansas Louisiana management allowed him to take an old compressor station and do a complete "before" analysis on it.
