By using HATS (Head and Torso Simulator) complying with IEC60959 (HATS), measurement in consideration of reflection and diffraction of sound has been attained.
A microphone is omni directional, enabling to record with full presence as experienced with real human ears.
Evaluation of headphone or earphone has been put in practical use, as well as high precision sound analysis in an architectural acoustic field has become possible by using a sound card and FFT analyzer
