Voice assistants and other sound design are actively developing now. Companies select the tone of voice for assistants, make even several of them, so that everyone can find a suitable one in mood and timbre. But in many other areas, less attention is paid to sound design.
For example, there is a sound standard for all heart monitors, ventilation systems and other vital pieces. On the ISO / IEC 60601-1-8 page, you can listen to the signals (but you probably already have a rough idea of them if you've watched at least one medical series).
Anesthesiologist Dr. Block, who was on the committee that adopted the standard, then said, "We did our best, but the sounds were mostly terrible." It turned out that the tunes were not tested before being applied.
The signals were created in such a way as to encrypt the phrase in themselves, so the number of syllables coincides with the number of notes, and pauses between syllables are repeated.
