New Measurement Techniques for Portable Listening Devices: Technical Report

Cory D.F. Portnuff

Measuring output characteristics of portable listening devices (PLDs), such as MP3 players, is critical to assessing the potential risk of music-induced hearing loss from use of these technologies. However, the current methods of measurement require expensive measurement equipment in the laboratory. This paper reports on two novel measurement techniques using a dosimetry system and a clinical probe-microphone system. These new techniques provide alternative measurement methods that will allow researchers to gather accurate and convenient measures of PLD output levels outside of the laboratory setting.
