audio surveillance
Covert sound monitoring
Audio surveillance is the monitoring or recording of sounds, especially conversations, typically without the knowledge of those being observed.
It encompasses wiretapping, bugging rooms with hidden microphones, and other covert listening methods: The FBI conducted audio surveillance of the suspect's apartment.
The term appears frequently in legal and intelligence contexts, where questions of privacy and warrant requirements arise.
