    An Evaluation of Entropy Measures for Microphone Identification by Gianmarco Baldini, Irene Amerini

    Published in Entropy (2020-10-01)
    “…Research findings have shown that microphones can be uniquely identified by audio recordings since physical features of the microphone components leave repeatable and distinguishable traces on the audio stream. …”

    Quantum Optical Microphone in the Audio Band by Raphael Nold, Charles Babin, Joel Schmidt, Tobias Linkewitz, María T. Pérez Zaballos, Rainer Stöhr, Roman Kolesov, Vadim Vorobyov, Daniil M. Lukin, Rüdiger Boppert, Stefanie Barz, Jelena Vučković, J. Christof M. Gebhardt, Florian Kaiser, Jörg Wrachtrup

    Published in PRX Quantum (2022-06-01)
    “…Capitalizing on the robustness and high sampling rates of our device, we implement a quantum optical microphone in the audio band. Its performance is benchmarked against a classical laser microphone in a standardized medically approved speech-recognition test on 45 subjects. …”

    Nonlinear Distortion of the Fiber Optic Microphone by Muhammad Taher Abuelma'atti

    Published in Active and Passive Electronic Components (2000-01-01)
    “…Analytical expressions are obtained for predicting the harmonic and intermodulation performance of the fiber optic microphone. These expressions are in terms of the ordinary Bessel functions with arguments dependent on the amplitudes of the acoustical exciting signal.…”

    Shooter Localization in Wireless Microphone Networks by David Lindgren, Olof Wilsson, Fredrik Gustafsson, Hans Habberstad

    “…Shooter localization in a wireless network of microphones is studied. Both the acoustic muzzle blast (MB) from the gunfire and the ballistic shock wave (SW) from the bullet can be detected by the microphones and considered as measurements. …”

    Method to reduce microphonics in superconducting resonators by S. Ghosh, P. N. Patra, B. K. Sahu, A. Rai, G. K. Chaudhari, A. Pandey, D. Kanjilal, A. Roy

    “…The control of superconducting resonators requires a large amount of rf power due to their narrow bandwidth and the presence of microphonics in the ambience, although only a small part is dissipated inside the resonator to generate the accelerating field. …”
