This is an unflown example of a Cockpit Voice Recorder, similar to those that have been installed in most commercial US aircraft since the 1990s. It recodes sounds in the cabin, including voices but also background sounds such as the engines or other noises, that may be very helpful to investigators trying to find the cause of a crash.
