Adaptation of a Pocket PC for use as a wearable voice dosimeter

Abstract

This article deals with the adaptation of a commercially available Pocket PC for use as a voice dosimeter, a wearable device that measures the vocal dose of teachers or other individuals on the job, at home, and elsewhere during the course of an entire day. An engineering approach for designing a voice dosimeter is described, and design data are presented. Technical issues include transducer selection, dynamic range, frequency response, memory requirements, power requirements, attachment, cables, connections, and data collection. Advantages and disadvantages of the design are discussed. ©American Speech-Language-Hearing Association.
