Abstract
An audio device for receiving radio communication. The audio device is configured to receive radio communication as a received radio signal. The audio device includes a hear-through element configured to provide a hear-through signal to a user in response to a received ambient sound signal, and an adaptive auto-gain element configured to perform an auto-gain function of the received radio signal according to an adaptive gain value resulting in a modified radio signal, and to set the adaptive target level for the auto-gain function in response to the hear-through signal.
Claims20
An audio device for receiving radio communication, the audio device
- being configured to receive radio communication as a received radio signal, the radio communication including audio,
- wherein the audio device comprises
- a hear-through element configured to provide a hear-through signal to a user in response to a received ambient sound signal, and
- an adaptive auto-gain element configured
- to perform an auto-gain function of the received radio signal according to an adaptive gain value resulting in a modified radio signal,
- to set the adaptive gain value for the auto-gain function in response to the hear-through signal,
- to maintain the adaptive gain value for the auto-gain function at a current level when the hear-through signal would otherwise be above but kept about a predetermined first level and the received ambient sound signal is below a predetermined second level, wherein the predetermined second level is higher than the predetermined first level, and
- to adaptively increase and decrease, respectively, the adaptive gain value for the auto-gain function as a function of
- the hear-through signal, and/or
- the received ambient sound signal, when the received ambient sound signal is above the predetermined second level or a predetermined third level;
- an adding element configured to add the audio of the modified radio signal with the hear-through signal to produce an overall sound signal that is provided to a speaker.
