We would like to inform you that the report on the project "Advancing Music Culture Under COVID-19: Verification Experiment on Droplet Infection Risks in Vocal Music and Choir" was released on December 11, 2020, by the Japan Classical Music Association, the Japan Orchestra Federation, and the Classical Music Park Promotion Council. The experiment was conducted in a high-performance clean room at the New Japan Air Conditioning research facility, aimed at detecting the fine particles generated during singing by professional vocalists. *For detailed materials (report), please visit: https://ebravo.jp/archives/70422 This document reports valuable insights that are not only relevant to us in the aerosol field but also provide very interesting findings regarding new lifestyles under COVID-19, based on experiments using New Japan Air Conditioning's fine particle visualization system and particle counters. We encourage you to take a look.
