Lecture on audiology from GISU Academy of Digital Technologies and Entrepreneurship 2024

We are pleased to invite you to attend the next lecture of the Academy of Digital Technologies and Entrepreneurship programme, which will be held on Tuesday, 16 April, from 15:00 to 17:00 (Beijing time).

Lectire topic: Binaural Bone-Conduction Sound Reproduction and Space Perception

Lecturer: Professor Stefan Stenfelt from Linköping University (Sweden)

Access to Zoom meeting will be provided to registered participants on the eve of the lecture.

This program explores auditory perception in which natural hearing primarily involves the reception of airborne sound through the ear canal with subsequent transmission to the inner ear facilitated by the middle ear ossicles. However, an alternate pathway for auditory sound involves transmission through the skull bone, where vibrations are directly conveyed to the bone encapsulating the inner ear. This process transforms these vibrations into sound pressure within the cochlear fluids, giving rise to a perceptual experience of hearing. Termed bone conduction, this mode of auditory perception is inherent and notably contributes to our ability to hear our own voices.

In audiological contexts, bone conduction assumes significance, particularly in the administration of hearing tests employing bone conduction stimulation. Furthermore, for individuals unable to use conventional hearing aids yet requiring amplification, bone conduction hearing aids have emerged as vital alternatives. Recently, bone conduction headsets for communication or listening have gained popularity, owing in part to their design that leaves the ear canals unobstructed, allowing users to maintain awareness of environmental sounds during prolonged use. In addressing the challenge, an adaptive algorithm tailored to estimate sound transmission from one side to the opposite side will also be presented.
