Informed Sound Source Localization Using Relative Transfer Functions for Hearing Aid Applications

Single-Channel Sound Source Localization Based on Discrimination of Acoustic Transfer Functions

Many systems using microphone arrays have been tried in order to localize sound sources. Conventional techniques, such as MUSIC, CSP, and so on (e.g., (Johnson & Dudgeon, 1996; Omologo & Svaizer, 1996; Asano et al., 2000; Denda et al., 2006)), use simultaneous phase information from microphone arrays to estimate the direction of the arriving signal. There have also been studies on binaural sour...

Sound Attenuation by Hearing Aid Earmold Tubing

In this study we model the sound attenuation properties of a hearing aid earmold tube. The model includes thermoviscous acoustic effects and it couples structural vibrations to the external acoustic field. Moreover, the finite element domain is coupled at two boundaries with an electroacoustic model of a hearing aid and an acoustic 2-cc coupler.

Biomimetic Sound-Source Localization

Sound-source localization systems typically comprise free-field microphone arrays. In nature, directional acoustic sensing evolved to rely on diffraction about the head with only two ears. For localization, the brain uses the resultant frequency-dependent acoustic phase and intensity differences between the two ears. We conceive a biomimetic artificial head with microphones placed on its surfac...

Sound source localization by hearing preservation patients with and without symmetrical low-frequency acoustic hearing.

The aim of this article was to study sound source localization by cochlear implant (CI) listeners with low-frequency (LF) acoustic hearing in both the operated ear and in the contralateral ear. Eight CI listeners had symmetrical LF acoustic hearing and 4 had asymmetrical LF acoustic hearing. The effects of two variables were assessed: (i) the symmetry of the LF thresholds in the two ears and (i...
