What is it about?

The assessment of firearm noise exposure is complicated because the sound pressure levels are typically in excess of 150 dB peaks. When assessing the exposure using a microphone at a fixed location, the measurement accuracy is compromised when the subject moves nearer or further from the microphone. This innovative system measures the noise in the ear canal of the subjects and tracks their locations on an outdoor firing range. We examine the exposure levels for the five subjects during a live fire exercise and report on their exposures

Why is it important?

This study is the first that has location information, in-ear and on-body dosimetry measurements, and a comprehensive noise mapping of the exposure throughout the exercise. It compares different methods to estimate the exposure and demonstrates the superiority of the in-ear dosimeter.
