Even/Odd-Mode Analysis of Cochlear Acoustics: Coupling of Odd-Mode Sound Waves with Traveling Waves
Abstrak
In this study, a straight cochlear model with a symmetric structure was utilized to elucidate the mechanism of traveling wave excitation. It was demonstrated that even-and odd-symmetric sound wave components are generated within the cochlea, and the cochlear acoustic phenomena can be described as their superposition. Furthermore, it was reported that the odd-symmetric sound wave component couples with the traveling wave, propagating through the cochlea at the same speed as the traveling wave while transferring energy to it.Clinical Relevance— A highly versatile cochlear model capable of detailed analysis of cochlear mechanisms has been developed. As it can be applied not only to cochlear physiology but also to acoustics-based auditory disorders — such as perilymph fistula, round window atresia, pneumolabyrinth, and Meniere’s disease — this model offers significant potential for widespread use in auditory healthcare.
