Performance evaluation is often conducted in idealized simulation environments assuming omnidirectional sources.\nHowever, real-world arrays may deviate significantly from theory: drivers exhibit manufacturing variations, frequency-dependent directivity patterns and there may be acoustic leakage between elements. Room boundaries introduce reflections that degrade theoretical beam structure.\nThis thesis aims to quantify these imperfections, understand their individual and combined effects, and assess how they impact beamforming algorithm performance.\nGoal\nThe objectives below are suggestions rather than strict requirements. We will decide together which objectives to focus on and whether to adjust them to fit your interests and the direction of the thesis.\nMeasure and characterize imperfections in a physical loudspeaker array like driver variations, directivity patterns and inter-element acoustic leakage.\nQuantify the relative impact of each imperfection on beam focus and algorithm robustness.\nCompare theoretical algorithm performance against measured results and identify which design factors matter most.\nInvestigate, evaluate and suggest methods for calibration.\nWho are you?\nFor this thesis proposal we target students with strong interests in acoustics, audio signal processing, and experimental validation. Most likely you are studying a Master Program in Electrical Engineering, Engineering Physics, Audio Technology, or Acoustics.\nOK, I am interested! What do I do now?\nApplications are accepted in both Swedish and English, and you apply via the proposal advert.\nThe announced thesis is open only to students affiliated with a Swedish University/College either directly or via an exchange program.\nWhen the thesis proposal states that it includes two students working together, we would like you to apply in pairs. In these cases, send one application each but make sure to clearly state in your application who your co-applicant is. If you have any questions regarding this, please do not hesitate to contact us.\nPlease attach your CV and University/College grade summary.\n Who to contact for any questions regarding the position!\nPlease contact Eric Liljeblad, +46 722 440 017.\nType of Employment\nThesis Worker (Fixed Term)Posting End Date\n2026-12-04Certain roles at Axis require background checks, which means applicable verifications will be done in these recruitments.
