Project Description

shirtThe Ambulatory Phonation Monitor (APM), Model 3200, is a portable device worn by a client in order to extract important parameters of vocal behavior over an entire day of normal activities.

Developed collaboratively by KayPENTAX, Sensimetrics Corporation, and clinicians at Massachusetts General Hospital, APM is based on years of research and addresses the important issue of how individuals use their voices throughout the day. APM can also help clients with carryover of therapy goals outside the clinical environment via the use of real-time vibrotactile feedback.

Data analysis includes both graphic and numeric displays of total phonation time, average fundamental frequency (Hz), and amplitude values (dB SPL).
