An investigation into the effect of sweat and moisture on the performance of in-ear monitors
|Hill, A., Gilmour, R and Burton, J.
In-ear monitors are used widely in the live event industry, allowing performers precision control of their personal monitoring system while suppressing interference from the external environment. This paper presents the results of an experiment on the effect of moisture, primarily sweat, on the acoustical output of in-ear monitor transducers. A 3D model of a test subject’s ear was constructed with custom moulded in-ear monitors inserted. Electroacoustic testing was carried out at various sound levels with an artificial sweat solution applied to the model. Results indicate that moisture has the potential to enter the ear canal due to capillary action, affecting the listening experience in terms of frequency response and overall level. Recommendations are provided based on this research, pointing to further necessary investigations.
