Database of multichannel in-ear and behind-the-ear head-related
An eight-channel database of head-related impulse responses (HRIR) and binaural room impulse responses (BRIR) is introduced. The impulse responses (IR) were measured with three-channel behind-the-ear (BTE) hearing aids and an in-ear microphone at both ears of a human head and torso simulator. The database aims at providing a tool for the evaluation of multichannel hearing aid algorithms in hearing aid research. In addition to the HRIRs derived from measurements in an anechoic chamber, sets of BRIRs for multiple, realistic head and sound-source positions in four natural environments reflecting daily-life communication situations with different reverberation times are provided.
The scenes' natural acoustic background was also recorded in each of the realworld environments for all eight channels. Overall, the present database allows for a realistic construction of simulated sound fields for hearing instrument research and, consequently, for a realistic evaluation of hearing instrument algorithms.
This database was published within the context of a special issue on
"Digital Signal Processing for Hearing Instruments"
EURASIP Journal on Advances in Signal Processing.
