  1. 1. Acoustic perception of Metal live performance in a multipurpose hall (Black Box) : A study into the influence of the acoustical quality of a Black Box regarding Metal live performance.

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    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

  2. 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.

  3. 3. Automatic Maximum Sound Pressure Level (SPL) Measurements Inside Cars

    University essay from KTH/Teknisk akustik

    Author : Luyao Dong; [2023]
    Keywords : Audio Measurement; Distortions; Maximum Sound Pressure Level SPL ; Automotive Audio; Ljudmätning; distorsion; maximal ljudtrycksnivå; billjud;

    Abstract : With a growing interest in technical specifications among consumers, there is a need for accessible measurement tools that enable individuals to evaluate the performance of their equipment, including common speakers and car audio systems, beyond what the manufacturer provides. However, the existing measurement systems are often geared towards professionals. READ MORE

  4. 4. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    University essay from Uppsala universitet/Signaler och system

    Author : Felix Gustafsson; [2022]
    Keywords : Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Abstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

  5. 5. Creative development of lightweight façade constructions in modular housing : The struggle to shut out the noise of the world

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Johan Albihn; [2022]
    Keywords : Acoustical engineering; façade wall construction; modular housing; traffic noise reduction; lightweight construction; industrial design engineering; Akustik; fasadväggkonstruktion; modulhus; reducering av trafikbuller; lättviktskonstruktion; teknisk design;

    Abstract : Modular construction of housing is an industry on the rise. The prefabrication of construction modules gives a greater control over material consumption, promotes standardization, and lessens the disturbance during the construction time in the field. Lindbäcks Bygg AB prefabricates housing modules in their factory at Haraholmen, Piteå. READ MORE
