  1. 11. Exploiting the Overtones in Online Localization of Sound Sources

    University essay from Lunds universitet/Matematisk statistik

    Author : David Sundström; [2022]
    Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

    Abstract : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. READ MORE

  3. 12. Optimization Approaches for Feedback Delay Networks

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

    Author : Johannes Hörngren; [2022]
    Keywords : ;

    Abstract : Feedback delay networks are systems based on a set of delay lines whose outputs get fed back into each others inputs. This kind of architecture is mainly used to provide a system for artificial reverberation, that is, a system to emulate the prolonging of sound in a physical space. READ MORE

  4. 13. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

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

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  5. 14. A comparison of binaural recordings performed in six different room configurations

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Denice Perkhed; [2021]
    Keywords : Binaural recordings; absorbtion coefficient; reverberation time; anechoic chamber; listening test; Psychoacoustics; Technology and Engineering;

    Abstract : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. READ MORE

  6. 15. Analysis of RISE's VIRC for Automotive EMC Immunity Testing

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Andreas Lundberg; [2021]
    Keywords : Electromagnetic Compatibility EMC ; Reverberation Chamber RC ; Vibrating Intrinsic Reverberation Chamber VIRC ; Cumulative Distribution Function CDF ; Rayleigh Distribution; Vector Network Analyzer VNA ; Immunity testing;

    Abstract : RCs (Reverberation Chambers) has historically been used mainly for aerospace and military purposes in EMC (Electromagnetic Compatibility) testing, but the interest also seems to increase in the automotive industry (the development of an international standard for vehicles is in progress). The vehicles of the future will most likely be electrified, wirelessly connected and autonomous, i. READ MORE
