  1. 1. 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.

    Keywords : Tissue paper; Embossing; Model; FEM; Mjukpapper; Prägling;

    Abstract : Tissue paper is a type of soft, absorbent, and lightweight paper with several applications for hygiene and kitchen use. Embossing is an operation during the converting stage of the tissue production process which creates relief designs on tissue. READ MORE

  6. 5. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

    University essay from KTH/Betongbyggnad

    Author : Stella Harrison; Siri Nöjd; [2021]
    Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

    Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE
