Abstract(in English) In rock concerts and live performances, earplugs are used to prevent ear damage due to loud sounds. The authors have investigated the sound insulation performance and feeling of use of commercially available earplugs for music and reported that they are suitable for listening to music from ordinary earplugs. However, since the music ear plugs have lower sound insulation than the usual earplugs, there is a possibility that insufficient sound insufficiency may cause hearing damage in places where very large music is played. In this research, we trialed an electronic earplug that can solve this problem. Specifically, by attaching a device in which an earphone and a microphone are integrated, it is possible to automatically adjust the sound insulation amount according to the input level level. Adjustment of sound insulation amount was made mainly by applying wide dynamic range compression technology used in hearing aids. As a result of evaluating the sound insulating property of the prototype electronic earplug, it was confirmed that the sound insulation amount gradually increased from the sound pressure level of 80 dB or more, and that sound insulation of 15 dB or more was realized for the sound of 110 dB or more. Also, subjectively evaluated the feeling of use and the sound quality, it was confirmed that it is superior to the commercially available earplug for music.
