Abstract: To examine the appropriate information disclosure method of noise as the final goal, we firstly set the goal to grasp the degree of understanding of the dB values of the sound sources among people other than acoustic experts. In this paper, first, in order to measure the degree of understanding of the dB in university students without expert knowledge, we developed a loudness chart kit and evaluated the understanding of loudness in the classes. As a result, they commonly regarded the sound volumes of the rocket and the take-off of the airplanes as first or second loudest, but the subjective ranks of other sound sources were completely different among them. Some of the students who seem to have no knowledge at all about the sound source answered unreality values entirely. Furthermore, since the university class was brought online due to the influence of the new coronavirus, we developed an online version of this teaching material. In the future, we will measure the changes in the evaluated dBs after learning the dB values. Then, we also accumulate more data about the differences of the understanding degree in dB values among the individual characteristics including their university, nationality, and whether they are environmental officials, to discuss the diagnostic criteria of the volume of the sound. Moreover, we will discuss how to learn a sense of loudness and dB. This reports on the online version of the teaching materials developed as university class are now online due to the impact of the novel coronavirus.
