Abstract :
Recent literature suggests a correlation between the acoustic signals produced by working muscles and the health, effort, and fatigue levels of the muscles. Practical experience gained in setting up a computer-based system to acquire and analyze the myoacoustic signal is discussed. Topics discussed include: obtaining the low frequency (5-50-Hz) signals; signal-to-noise ratio; protocol; and artifact considerations. Preliminary results indicate that large artifact signals are inherent in the frequency range of interest. A simple signal and transducer model is proposed to explain these observations
