Influence on the sound post processing by installing acoustic panels in a personal music production studio

With the development of digital signal processing techniques and the spread of social media, opportunities for music production in private studios/rooms are rapidly increasing. In music production, acoustic adjustment is required in various processes of recording and sound source production. The acoustic characteristics and ambient have a large impact on the results of the acoustic adjustment, however the specific effects have not identified. In this study, we investigated the impact of sound-absorbing panels on room acoustics by comparing key acoustic indices (clarity (C80), reverberation time (RT), and early decay time (EDT)) measured with changing the position of sound absorbing panels. Additionally, we assessed the effect of acoustic adjustments on sound mixing through subjective evaluations using major and minor key music. Participants included music producers, instrumentalists, and individuals with no musical experience. Participants adjusted the reverberator and equalizer in acoustic environments with different acoustic characteristics using acoustic panels, and the amount of adjustment was verified. As a result, the differences in the amount of acoustic adjustment depending on whether or not an acoustic panel was observed. Especially, with considering the experience in music production, the differences were also confirmed depending on the amount and trends in acoustic adjustment.
