Abstract: There is provided a method of determining a transmission quality when receiving audio signals which are transmitted over a frequency-modulated path in analog form. For that purpose a frequency-modulated audio signal is received and IQ demodulation of the input signal is implemented. The I- and the Q-path of the demodulated baseband signal are subjected to analog/digital conversion. Alternatively the input signal can first be digitized and then subjected to IQ demodulation. A multiplicity of N samples is detected. The amount of the N samples is formed. A reference value is determined from the amount of the N samples. Each of the N samples is standardized to the reference value. A measurement in respect of the fluctuations in the standardized amounts is determined. The measurement in respect of the fluctuations indicates the quality of the transmission path.

Abstract: There is provided a microphone device comprising a camera having a field of vision for acquiring image data, a microphone unit with adjustable directivity and a control unit for adjusting the directivity of the microphone unit. Adjustment of the directivity of the microphone unit is based on ascertained position information of at least one user in the field of vision of the camera. The camera and/or the control unit are adapted to ascertain position information of at least one user from the image data acquired by the camera.
