A method, a system, and a server for reducing noise in a workspace are disclosed. The workspace may have a plurality of terminals connected to a server via a communication network. The method may include detecting a noise level, which is above a predetermined threshold value, in or adjacent to at least one of the terminals. The noise level in or adjacent to a terminal may be detected by monitoring noise emitted from or in the vicinity of that terminal by a microphone associated with that terminal. The method may also include identifying the terminal at which the noise level exceeds the predetermined threshold. Further, the method may include initiating a measure for reducing the noise level.

An intercom system provides audio communication between multiple users wearing head-mounted devices (HMDs). In an embodiment, the intercom system determines a first location of a first HMD of a first user. The intercom system determines a second location of a second HMD of a second user. The intercom system receives audio of the first user from a microphone of the first HMD. The intercom system determines a volume level of the audio at the second location using at least the first location and the second location. The intercom system transmits the audio to the second HMD responsive to determining that the volume level is less than a threshold volume. The intercom system may also selectively transmit audio based on gaze direction of a user. Additionally, the intercom system may generate a transcript of audio input by users.
