Acoustic design of music recording studio room (English)
Abstract [sv]

Detta projekt genomfördes i samarbete med akustikern Erling Nilsson på företaget Ecophon i Hyllinge. Uppdragsgivare var musikproducenten Magnus Ågren som äger studion Flow Music i Malmö. Uppgiften var att förbättra akustiken i ett av Flow Musics studiorum. Rummet hade före projektet en hård och obehaglig akustik. För att komma fram till ett åtgärdsförslag specificerades först hur enskilda akustiska egenskaper skulle påverkas för att ge ett så bra resultat som möjligt. Utvärderande undersökningar visade sedan att samtliga parametrar påverkats i rätt riktning, om än inte alla så mycket som beräknat. Åtgärderna gick i huvudsak ut på att tillföra absorption i mellanregister och diskant samt att diffusera ljudfältet så mycket som möjligt. De utvärderande mätningarna visar att lite mer absorption och diffusion i de låga frekvenserna kan behövas.

Abstract [en]

This project was carried out in collaboration with acoustics specialist Erling Nilsson at Ecophon in Hyllinge, Sweden. The job requester was music producer Magnus Ågren, owner of Flow Music Studios in Malmö. The task was to improve the acoustics in one of the rooms used for recording. Prior to the measures, the sound quality was rather poor with a harsh and unpleasant character. First, the way in which certain acoustic parameters should be affected was defined. Thereafter, measures were suggested with the target values in mind. Evaluating studies later showed that the parameters had been affected in the right direction, though not all of them as much as calculated. The main goal of the acoustic treatment was to add absorption in the middle and high frequencies, and to diffuse the sound waves as much as possible. Acoustic measurements also showed that the room might profit from a little more absorption and diffusion in the low frequencies.
