It has been held annually since 1972, and this was its fourth iteration in Japan, after a 12-year gap since the previous one. It was attended by researchers, engineers, professors, manufacturers, and stu-dents from all over the world, with a total of 1,272 registered participants and 883 presentations (oral, pre-recorded, and poster sessions).Many staff members from Rion and Norsonic also par-ticipated. The four days of presentations covering various research themes provided a valuable opportunity to meet and have discussions directly with many researchers and engineers from both Japan and abroad.The conference also featured numerous programs intro-ducing Japanese culture to overseas participants, such as les-sons on calligraphy, origami workshops, and an opportuni-ty to try on a yukata, providing them with enjoyable experi-ences of Japanese culture.During the conference, acoustic manufacturers from around the world exhibited their products. Among the some 31 companies/organizations participating, Rion supported Inter-Noise 2023 as a manufacturer from Japan and plati-num sponsor, and together with its group company Norson-ic, secured the largest exhibition space. We introduced our sound level meters, vibration meters, frequency analyzers, and other measuring instruments and services at our booth, providing us with the opportunity to interact with many conference participants.Inter-Noise 2024 is scheduled to be held in Nantes, France. Rion plans to sustain its involvement in internation-al academic meetings by presenting research and exhibiting our instruments, thereby engaging with participants.Rion’s presentations (including joint research)17Venue of Inter-Noise 2023Japan held the conference for the fourth time after a twelve year absence.As a manufacturer from the host country, Rion supported the conference and participated in the presentations and exhibitions.Report on Inter-Noise 2023
