Head-Related Transfer Functions of Children
Several detailed investigations into the head-related transfer functions (HRTF) of adults have been performed in the past. However, little information is available about the effects of growth-dependent geometrical data of the head and torso of children and on the corresponding HRTFs.
At first a database containing anthropometric data of children aged four to six years was created and the data were analysed. Due to difficulties involved during direct measurements of HRTFs of children, detailed and simplified CAD models were created and HRTFs obtained by numerical simulations.
The results are discussed with regard to age-dependent binaural cues and concerning further steps required for head and torso simulators applicable for measuring close-to-the ear sources like hearing aids.
