Application of Stereophonic 3D real-time sound and speech processing to conductive hearing loss: A Case Report

Abstract: Background: Stereophonic 3D sound processing offers new rehabilitative strategies for conductive hearing loss (CHL) by simulating natural acoustic environments, enhancing spatial awareness and speech understanding. These technologies mimic sound wave interactions with the head and ears, potentially easing challenges faced by those with CHL. However, their clinical application remains limited, as research has primarily targeted sensorineural hearing loss and cochlear implants. There is a pressing need to assess their effectiveness for conductive impairments in real-world settings. This case report seeks to evaluate the use of advanced sound processing techniques in clinical practice, focusing on functional outcomes and user experiences. Methods: This report presented a boy, aged 3.5 years, with conductive hearing loss (mild to moderate) in both ears, due to secretory otitis media (fluid in the middle ear). Through speech therapy sessions with application of combined use of bone conduction headphones and stereo three-dimensional sound & speech processing in real time, there was a significantly accelerating child's linguistic and social development, offering them an auditory experience as close as possible to normal hearing. Conclusions: The combined use of Bone Conduction Headphones and Real-Time Stereo 3D Sound & Speech Processing can create a rich, spatially oriented, auditory environment that: a) Restores auditory accessibility to children with conductive hearing loss, b) Accelerates phonological development, c) Cultivates spatial hearing and attention skills, and d) Creates a positive learning cycle.
