INTRACANAL PROSTHESIS FOR HEARING EVALUATION

摘要

A hearing evaluation and hearing aid fitting system (22) provides a fully immersed, three-dimensional acoustic environment to evaluate unaided, simulated aided, and aided hearing function of an individual. Digital filtering of one or more signal sources representing speech or other audio-logically significant stimuli according to selected models and digitally controlled signal processing parameters produce a simulated acoustic condition for presentation to a hearing impaired person for hearing evaluation.
