A multiple model high-resolution head-related impulse response database for aided and unaided ears

Year: 2019

Type: article

Abstract: Head-related impulse responses (HRIRs) allow for the creation of virtual acoustic scenes. Since in ideal conditions the human auditory system can localize sounds with a very high degree of accuracy, it is useful to have an HRIR database with high spatial resolution, such that realistic-sounding scenes can be created. In this article, we present an HRIR database with 12722 directions, giving a spatial resolution of 2 arc degree or better, for a sphere covering − 64∘ elevation to the zenith. Four sets of HRIRs were recorded with different head-and-torso simulators (HATSs), including one with a six-channel bilateral behind-the-ear hearing aid model. The resulting database is available at https://www.uni-oldenburg.de/akustik/mmhr-hrtf and is distributed under a Creative Commons license.
