The Museum of Endangered Sounds, an online exhibit, went live on July 19, 2026, and provides audio recordings of sounds from now‑obsolete technologies. Visitors can click icons to play the recordings.

The exhibit reflects growing interest in preserving digital heritage as older communication and computing devices disappear from daily use. Similar projects have emerged to document the auditory experience of early internet and consumer electronics.

The interface displays a series of icons representing different sound sources, such as AOL Instant Messenger chimes, teletype machines, floppy disk drives, dial‑up modems, and Tamagotchi alerts. Selecting an icon triggers playback of the corresponding audio file. The collection includes recordings of these and other legacy sounds. The project is attributed to Terrence O'Brien, whose name appears in the article byline. The site is accessible without registration and requires no additional software.

The exhibit remains available online, offering a reference for those interested in the history of digital sound.
