Abstract

New headphone frequency response measuring scheme was standardized as JEITA RC-8140B-1 in March 2016. The basic idea of the scheme is that the frequency response is to be measured by HATS and compensated by a free-field HRTF of HATS used in the measurement. One of the advantages of this measuring scheme is that obtained results have equivalent implication with the results of free-field frequency response of the loudspeakers. This report supplements the previous report that proposed the basic idea of above-mentioned scheme by adding topics regarding newly developed HATS to improve signal to noise ratio in high frequency areas above 20 kHz with ear simulators.
