Abstract
An electronic earplug for wideband control of pressures at, the tympanic membrane is presented. A unique methodology of determining effective component placement inside an earplug that provides acoustic isolation between the ambient noise and tympanic membrane is explained. Methods for providing accurate dosimetry and improved active control result from the unique earplug design process, leading to very wideband active noise reduction at the tympanic membrane.
