TONAR calibration: a brief note.
Abstract
Measurements were made of the frequency response characteristics of the microphone-separator components of TONAR II instrumentation. The results of our calibration studies revealed 1) appreciable non-uniformity in frequency response of the two microphones, 2) a considerable degree of mismatch in frequency response between the microphones and, 3) dynamic interactions among microphone, separator cavity, and talker cavity resonant characteristics. Findings are discussed in terms of their implications regarding the validity of TONAR II based nasalance ratio measures.
