There
has been increasing attention in the literature to wearable acoustic
recording devices, particularly to examine naturalistic speech in disordered
and child populations. Recordings are typically analyzed using automatic
procedures that critically depend on the reliability of the collected signal.
This work describes the acoustic amplitude response characteristics and the
possibility of acoustic transmission loss using several shirts designed for
wearable recorders. No difference was observed between the response
characteristics of different shirt types or between shirts and the
bare-microphone condition. Results are relevant for research, clinical,
educational, and home applications in both practical and theoretical terms.
