In internally coupled ears (ICE), eardrum vibrations are coupled through an air-filled interaural cavity. This dissertation presents a mathematical analysis of ICE’s role in generating sound localization cues in the form of time and amplitude differences between the ears. In particular, it analyzes the eardrum‘s role in segregating hearing into low- and high-frequency regimes. Its results also lead to a method of estimating the eardrum's material properties through in vivo measurements. The role played by ICE under water, incl. high-frequency hearing, is investigated as well.
