  • Method and device for generating and providing an audio signal for enhancing a hearing impression at live events
    Patent number: 10643597
    Abstract: A method for generating and providing an audio signal, including receiving a first audio signal via an external microphone of a headphone or earphone, and receiving a second audio signal via a wireless interface. The first audio signal includes a portion reproduced via loudspeakers. The second audio signal corresponds to the portion reproduced via loudspeakers and is received before the corresponding portion of the first audio signal. A propagation time difference is determined between the first audio signal and the second audio signal. The second audio signal is modified by adaptive filtering and temporal shifting such that the propagation time difference between the first and second modified audio signal is substantially compensated. The adaptive filtering models an acoustic transmission of the first audio signal and a modified second audio signal is obtained. The modified second audio signal is inverted, then it is provided via the headphone or earphone.
