  1. 1. Approach for frequency response-calibration for microphone arrays

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jacob Drotz; [2023]
    Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

    Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

  3. 2. Recording Bass-Cabinet: Microphone Choice and Microphone Placement

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

    Keywords : audio technology; recording bass; recording; bass; microphone choice; bass-cabinet; microphone placement; rock; ljudteknik; mikrofon val; bas; rock;

    Abstract : Research on microphone choice and placement has been previously made for a variety of instruments, such as drums, vocals, and guitar, to name a few. However, in comparison, very little research has been made on the bass-cabinet. READ MORE

  4. 3. Comparative analysis of contact and non-contact method for determining the natural frequencies of a bolted joint

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malin Dyberg; Elvira Troillet; [2023]
    Keywords : ;

    Abstract : To ensure high assembly quality of components, a proper clamping force in bolted joints is essential. The existing tightening technology rely on torque and angle; however, this thesis proposes a method for obtaining the clamping force of a bolted joint based on measuring the natural frequencies.

  5. 4. Stereo techniques and time delay compensation in classical music recording, the impact on the preferred spot microphone level in a mix

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

    Author : Oscar Thor; [2023]
    Keywords : audio technology; recording; classical music; stereo techniques; A B; ORTF; X Y; Blumlein; spot microphones; level; time delay compensation; clarinet; violin; piano;

    Abstract : This study investigates whether different stereo techniques used as a main array influences the preferred level from spot microphones when combined in a mix. Time delay compensation and its influence on spot microphone level was also examined. A clarinet soloist and a violin & piano duo were recorded as stimuli. READ MORE

  6. 5. Loudspeaker-Room Correction of Conference Rooms

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