  1. 6. Attenuation AND awareness? : Designing a method for measuring accuracy and certainty of sound identification when wearing a HPD

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

    Author : Markus Ahlberg; [2020]
    Keywords : Industrial design engineering; method design; sound identification; situational awareness; hearing protection devices; noise pollution; level-dependent function; Teknisk design; metoddesign; ljudidentifikation; situationsmedvetenhet; hörselskydd; buller; bullerföroreningar; nivåberoende funktion;

    Abstract : Noise pollution is widespread in today’s society, from traffic to industrial sources, and many people are confined to unhealthy acoustic environments through their employment. When noise cannot be eliminated at the sound source, the protective measure is usually to equip the employee with hearing protection devices (HPDs), e.g. READ MORE

  3. 7. Two-dimensional roughness and Tollmien-Schlichting waves: a study on transition

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Derek Micheletto; [2020]
    Keywords : ;

    Abstract : Two-dimensional (2D) roughnesses induce premature transition to turbulence in laminar boundary layers by amplifying the disturbances in the flow and promoting the development of non-linearities. The present thesis aims at furthering our understanding of this phenomenon's underlying mechanisms and elucidating the effects of the different geometrical parameters of the roughness' cross section.

  4. 8. Modeling and Compensation of Nonlinear Distortion in High Efficient Electrodynamic Loudspeakers

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Caroline Holmström; [2020]
    Keywords : ;

    Abstract : Loudspeakers transform electrical energy into acoustic waves but most of the electrical energy is lost as heat. It is possible to increase the electro-acoustic efficiency by changing the electrical, mechanical or acoustical design of the loudspeaker but with these changes come unwanted side effects. READ MORE

  5. 9. The Impact of the Difference Signal on the Perceived Loudness of a Piece of Stereo Rock Music : A Comparison Between Headphones and Loudspeakers

    University essay from Luleå tekniska universitet/Institutionen för konst, kommunikation och lärande

    Author : Joel Hansson Lagerberg; [2019]
    Keywords : Loudness; BS.1770; Headphones; Loudspeakers; Stereo; Perception;

    Abstract : The purpose of this study was to evaluate how the BS.1770 Loudness Standard is affected by the amount of difference signal present in the signal being measured, and if this affection is different between the two playback systems Headphones and Loudspeakers. The study was restricted to rock music productions in a stereo format. READ MORE

  6. 10. Virtual bass synthesis and balancing bass in pop music

    University essay from Luleå tekniska universitet/Institutionen för konst, kommunikation och lärande

    Author : Edward Swords; [2019]
    Keywords : VBS; Virtual Bass Synthesis; Sound engineer;

    Abstract : A bass enhancement technique using the missing fundamental called VBS is presented. There are Several different approaches for using VBS in different applications. The technique is most useful in speakers that has a poor low frequency capability. It is presented in this report how it can be used for mixing purposes. READ MORE
