   Author : Sam Soliman; [2023]
   Keywords : Metal; room acoustics; influence; live performance; parameters; acoustics;

   Abstract : A study has been implemented regarding the acoustical characteristics of a black box and its influence on rock and metal music live performance. Objective acoustical measurements have been made as well as a subjective evaluation in form of a listening test. READ MORE

3. 2. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

   University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Huong Nguyen; [2023]
   Keywords : Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

   Abstract : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.
