Communication hub and communication system

1. A communication hub for a communication system, with at least an audio I/O interface for connection with one or more communication sources to at least receive an input audio signal;

a user device interface for connection with at least one user audio device;

a processor to provide a user input audio signal to the user device interface from the input audio signal; and

a reporting module, configured to generate metadata of at least the input audio signal and to provide the metadata to a monitoring device of the communication system; wherein the one or more communication sources comprise one or more of the group of a phone, a mobile phone, a PSTN phone, a PSTN line, a VOIP line, and a VOIP interface; and wherein

the monitoring device is separate from the user audio device.

2. The communication hub of claim 1 , further comprising a network interface for communicating with the monitoring device.

3. The communication hub of claim 1 , wherein the user device interface is configured for wireless communication with at least one user audio device.

4. The communication hub of claim 1 , wherein the user device interface is configured for connection to a headset.

5. The communication hub of claim 1 , wherein the audio I/O interface is configured for connection with a plurality of communication sources.

6. The communication hub of claim 1 , wherein the processor is configured to receive a user output audio signal from the user device interface and to provide a corresponding output audio signal to the audio I/O interface, wherein the reporting module is configured to generate metadata of the input audio signal and the output audio signal.

7. The communication hub of claim 1 , further comprising a mode-switchable acoustic safety module with at least an enabled state and a disabled state, which mode-switchable acoustic safety module in the enabled state being configured to process the input audio signal to reduce acoustic shocks.

8. A communication system, with at least

one or more communication hubs; and

a monitoring device, connected with the one or more communication hubs;

wherein

each communication hub comprises

an audio I/O interface for connection with one or more communication sources to at least receive an input audio signal;

a user device interface for connection with at least one user audio device; and

a processor to provide a user input audio signal to the user device interface from the input audio signal; and

a reporting module, configured to generate metadata of at least the input audio signal and to provide the metadata to the monitoring device;

wherein

the one or more communication sources comprise one or more of the group of a phone, a mobile phone, a PSTN phone, a PSTN line, a VOIP line, and a VOIP interface; and wherein

the monitoring device is separate from the user audio device.

9. The communication system of claim 8 , wherein the monitoring device is configured to provide a safety notification in case an acoustic safety incident is determined.

10. The communication system of claim 8 , wherein the communication hub further comprises a mode-switchable acoustic safety module with at least an enabled state and a disabled state, which mode-switchable acoustic safety module in the enabled state being configured to process the input audio signal to reduce acoustic shocks.

11. The communication system of claim 10 , wherein the monitoring device is configured to enable to the mode-switchable acoustic safety module of at least one of the one or more communication hubs in case an acoustic safety incident is determined.

12. The communication system of claim 8 , further comprising one or more headsets, each being connected with the user device interface of at least one of the one or more communication hubs.

13. The communication system of claim 10 , wherein the monitoring device is configured to disable the acoustic safety module in case no acoustic safety incident is determined for a predefined time period.

14. The communication system of claim 10 , wherein the reporting module is configured to generate metadata when the mode-switchable acoustic safety module is enabled and when the mode-switchable acoustic safety module is disabled.

15. A method of processing audio with a communication hub of a communication system, wherein

at least one input audio signal is received from one or more communication sources;

the input audio signal is processed to provide a user input audio signal to a user device from the input audio signal;

metadata of the at least one input audio signal is generated; and

the metadata is transmitted to a monitoring device of the communication system;

wherein

the one or more communication sources comprise one or more of the group of a phone, a mobile phone, a PSTN phone, a PSTN line, a VOIP line, and a VOIP interface; and wherein

the monitoring device is separate from the user audio device.
