Due to the pandemic situation, it become complex to conduct subjective experiments in the anechoic chamber as a result of the lockdown. For this situation the procedure for the subjective experiments without accessing to the anechoic chamber needs to be considered for an alternative approach. The previous study has shown that there are good correlation between the laboratory and online listening test on impact sounds in residential buildings using ambisonic microphone recording with headphone. Hence, further subjective experiments were carried out with monaural and binaural microphone recordings in an experimental buildings in Japan. The subjective experiment using a headphone in anechoic chamber was held in AIST, Japan. The 3 different floor types, 2 different types of microphones (mono and binaural), at 12 different combinations of impact sources, excitation positions and microphone positions were tested. This study also provided some evidence, and suggested there are potential of the online/remote subjective experiment using headphone.
