1. A method for operating a secure audio firewall enclosure, wherein the secure audio firewall enclosure is configured with sound mitigation measures to suppress transmission of sound from an external environment outside of the secure audio firewall enclosure to an internal environment within the secure audio firewall enclosure, wherein the sound mitigation measures include a vacuum maintained within the internal environment by walls of the secure audio firewall enclosure, the method comprising:
detecting, from an audio recording captured in the external environment of the secure audio firewall enclosure, a passphrase uttered by a user; and
activating sound transmission measures of the secure audio firewall enclosure responsive to detecting the passphrase, wherein the sound transmission measures facilitate transmission of the sound from the external environment to the internal environment.
