1. A method, comprising:
measuring, by a processing device of a user videoconferencing device, a first set of acoustic data associated with a conference room during a video conference attended by a plurality of users, the first set of acoustic data indicating one or more first acoustic parameters comprising at least one of first reverberation time, first signal-to-noise ratio, or first absolute noise level of the conference room;
comparing, by the processing device of the user videoconferencing device, the one or more of the first acoustic parameters to one or more thresholds during the video conference;
providing, by the processing device of the user videoconferencing device, at least one of the first acoustic parameters or a result of the comparing to at least one user during the video conference;
measuring, by the processing device of the user video conferencing device, a second set of acoustic data associated with the conference room during the video conference attended by the plurality of users; and
providing, by the processing device of the user video conferencing device, to the at least one user during the video conference, an indication of whether the second set of acoustic data indicates an improvement compared to the first set of acoustic data.
