Abstract

This paper discusses the process of developing and analysing a multi-driver headphone for spatial audio using MEMS loudspeakers to reproduce pinnae dependent frequency shaping effects. MEMS Directional Transfer Functions from the headphone drivers are compared to the Kemar Head Directional Transfer Function using a broadband correlation function and in 1/3 octave band regions as per Blauert. Results show a statistically signi?cant correlation between the MDTFs and HDTFs with correlation coef?cients in the region above 0.6.The headphones do reproduce the individualised frequency shaping effects in the near ?eld similar to those caused by the far ?eld HRTF. The headphones are best able to reproduce the cues for front elevated and rear sources which correspond to MEMS speaker positions M2 and M4.
