  1. 1. 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

  2. 2. Design of equalization filter for non-linear distortion of the loudspeaker array with listener's movement

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Akshaya Ravi; [2018]
    Keywords : ;

    Abstract : The importance of the real-time virtual auditory environment is dependent on the fidelity of reproducing the sound. The loudspeaker array provided with its ideal response is suitable for the sound reproduction. However, there exists frequency and phase distortions in the loudspeaker response that cause audible artifacts at the listener's ears. READ MORE

  3. 3. Acoustic feedback suppression in audio mixer for PA applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Ekström; [2017]
    Keywords : Digital signal processing; feedback suppression;

    Abstract : When a speaker is addressing an audience, a PA system consisting of a microphone and a loudspeaker is often used. If the microphone picks up too much of the loudspeaker energy, acoustic feedback in the form of an unwanted characteristic howling can occur. READ MORE

  4. 4. Designing, building and validating a test rig to measure two-port data of small fans

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Emil Garnell; [2017]
    Keywords : ;

    Abstract : There is a great need in the industry for measurement methods to characterize acoustic sources in ducts. One way to obtain a complete description of a source is to measure 2-port data, comprising of the source scattering matrix and the source vector. The resulting model can then be used to predict the source properties, e.g. READ MORE

  5. 5. Automatic acoustic tests of conference phones

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Carl Christian Kirchmann; [2017]
    Keywords : Acoustics; Digital signal processing; total harmonic distortion; reverberation;

    Abstract : This master thesis was completed at Limes Audio in Umeå. Limes Audio are specialized in speech enhancement software which is mostly used in conference phones. Their software is used to reduce noise, echo cancellation as well as reduction of distortion. READ MORE
