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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

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

    Sammanfattning : 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.

  3. 2. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    Master-uppsats, KTH/Teknisk akustik

    Författare :Viktor Söderlund; [2023]
    Nyckelord :Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Sammanfattning : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. LÄS MER
