acoustic transmission การใช้

• Wind instruments consist of a tube which acts as an acoustic transmission line in which standing waves are set up.
• While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a given language or across languages to encode meaning.
• Being made independent of the terminations, TL finds favor with researchers who are sometimes interested in finding the acoustic transmission behavior of an element or a set of elements in isolation of the terminations.
• An acoustic transmission line is the analogue of the electrical transmission line, typically thought of as a rigid-walled tube that is long and thin relative to the wavelength of sound present in it.
• The theory of sound wave propagation is very similar mathematically to that of electromagnetic waves, so techniques from transmission line theory are also used to build structures to conduct acoustic waves; and these are called acoustic transmission lines.
• NCOs are used in many communications systems including digital up / down converters used in 3G wireless and software radio systems, digital PLLs, radar systems, drivers for optical or acoustic transmissions, and multilevel PSK modulators / demodulators.
• Someone has vandalised the page on acoustic transmission lines, that i painstakingly built a few years ago . i added information about the difference and definitions of acoustic transmission lines and to reflex enclosures, and pointed to the fact that the only authentic retail product available was the SUHTL.

• The later SPURVS were utilized on 1-2 cruises per year by Terry Ewart and the Applied Physics Lab's Ocean Physics Department Engineers and Research Scientists, conducting about 20 month-long cruises in total to study small scale ocean variability including internal wave and fine-structure data, point source release dye diffusion at 1000 meters, and oceanographic data for acoustic transmission experiments.
