Abstract (en)
[origin: WO2021122540A1] In a method for transmitting and reproducing acoustic information, acoustic data is provided which comprises a first data component and a second data component, wherein the first data component does not contain speech information, and the second data component contains speech information. Each piece of data is reproduced by first and second audio reproduction means (30, 40) such that all users (101, 102) can hear the acoustic signals emitted by the first audio reproduction means (30) together, and the acoustic signals emitted by the second audio reproduction means (40) can be heard substantially only by the corresponding user (101, 102).
