The measurement and /or graphing of acoustic (sound) information such as fundamental frequency, formant pattern and energies, decibel level (roughly, the loudness), signal-to-noise ratio, jitter, shimmer, and the like from the voice. At present it is difficult to find unique diagnostic information from any set of acoustic measures. Hence, acoustic analysis is arguably justified for now in the realm of voice research and when used as a feedback tool in the therapy room. Although this may change in the future, at present acoustic analysis is superfluous to the diagnostic process, and specifically to the integrative diagnostic model or method.
