Listening test results with a prototype system show that the proposed system has interesting properties. ![]() An overview of related technology, literature, and application scenarios is provided. Virtual sound events are then mixed with microphone signals to produce a hybrid, an augmented reality audio representation, for the user. When microphone signals are routed directly to the earphones, a user is exposed to a pseudoacoustic representation of the real environment. A framework is introduced for mobile augmented reality audio (MARA) based on a specific headset configuration where binaural microphone elements are integrated into stereo earphones.

Intracochlear pressure in cadaver heads under bone conduction and intracranial fluid stimulation. Characteristics of bone-conduction devices simulated in a finite-element model of a whole human head. Biomechanics and Modeling in Mechanobiology, 17, 1741–1755. Simulation of the power transmission of bone-conducted sound in a finite-element model of the human head. The Journal of the Acoustical Society of America, 140(3), 1635–1651. The development of a whole-head human finite-element model for simulation of the transmission of bone-conducted sound. Using a bone-conduction headset to improve speech discrimination in children with otitis media with effusion. This increased contribution from the ear canal sound pressure to BC hearing means that a position close to the ear canal is not appropriate for clinical use since, in such case, a conductive hearing loss affects BC and air conduction thresholds by a similar amount.īone conduction bone conduction pathways ear canal sound pressure headsets.īrown T., Salorio-Corbetto M., Gray R., Best A., Marriage J. With this stimulation, the ear canal pathway was estimated to be around 25 dB greater than other contributors, like skull bone vibrations, for hearing BC sound in a healthy ear. The findings suggest that with BC stimulation close to the ear canal opening, the sound pressure in the ear canal dominates the perception of BC sound. This decreased transcranial transmission facilitates saliency of binaural cues and implies that BC headsets are suitable for virtual and augmented reality applications. The transcranial transmission ranges typically between -40 and -25 dB. The results indicated that a stimulation position close to the ear canal opening improves the sensitivity for BC sound by around 20 dB but by up to 40 dB at some frequencies. ![]() The BC sound transmission for this stimulation position is here investigated in 21 participants by ear canal sound pressure measurements and hearing threshold assessment as well as simulations in the LiUHead. Recently, BC has become popular for communication headsets where the stimulation position often is close to the anterior part of the ear canal opening. Bone conduction (BC) stimulation has mainly been used for clinical hearing assessment and hearing aids where stimulation is applied at the mastoid behind the ear.
