Abstract
Head-related impulse responses (HRIRs) in the time domain, or head-related transfer functions (HRTFs) in the frequency domain, characterize the transmission between a sound source and the eardrums of a subject. They are different for each ear, angle of incidence, and also vary from person to person due to the anatomical differences. Individual measurement of HRIRs become required for applications where precise simulation of the acoustic scene is necessary, such as virtual auditory environments, and for validation of HRTF personalization methods. This presentation describes a HRIR measurement system, which uses as excitation signal logarithmic sine sweep or also binary sequences known as Golay codes. The system also has a 3D scanner mounted over detachable holders that captures the digital models of the pinnae as a mesh. The results of measurements carried out in a head and torso simulator with soft pinnae are presented.
