Background and Aim: The video head-impulse test (vHIT) measures the vestibulo-ocular reflex (VOR) driven by each semicircular canal, following high-acceleration head rotations. The main measurable response is the ratio of eye movement velocity to the angular head velocity, which reflects canal function. Although normative data is available for VOR gain, most studies only report horizontal VOR c...

We developed the head impulse testing device (HITD) based on an inertial sensing system allowing to investigate the functional performance of the rotational vestibulo-ocular reflex (VOR) by testing its gaze stabilization ability, independently from the subject's visual acuity, in response to head impulses at different head angular accelerations ranging from 2000 to 7000 deg/s(2). HITD was initi...

Natural-sounding reproduction of sound over headphones requires accurate estimation of an individual’s Head-Related Impulse Responses (HRIRs), capturing details relating to the size and shape of the body, head and ears. A stereo-vision face capture system was used to obtain 3D geometry, which provided surface data for boundary element method (BEM) acoustical simulation. Audio recordings were fi...

A technique for the recording of large sets of room impulse responses or head-related transfer functions is presented. The technique uses a microphone moving with constant speed. Given a setup (e.g., length of the room impulse response), a careful choice of the recording parameters (excitation signal, speed of movement) leads to the reconstruction of all impulse responses along the trajectory. ...

Binaural room auralization involves Room Impulse Responses (BRIRs). Dynamic binaural synthesis (i.e., head-tracked presentation) requires BRIRs for multiple head poses. Artificial heads can be used to measure BRIRs, but BRIR modeling from microphone array impulse responses (RIRs) is becoming popular since personalized obtained any pose with low extra effort. We present a novel framework estimat...

Audiological and vestibular testing plays an important role in diagnosis of Menière’s disease,as disease per se and as staging diagnosis. A battery of tests are recommended in order to have a better evaluation of the disease. Audiological testing includes pure tone audiometry, with highlights of bone conduction especially in acute episodes of Menière’s disease, speech audiometry and glycerol te...
