Description

The U.S. trademark registration for the sound contains this description of it:
While the Deep Note had originally been from a soft to loud pitch from its debut in 1983, the Deep Note over the years has been remixed digitally, with then-new technology, which made the Deep Note with a more abridged sound. Beginning notably in 1988 the Deep Note became louder and abridged, and in 1993 the Deep Note was cut short to save time for Laserdisc (1995 for VHS). Most recently, however, the Deep Note has been cut short to the single note (where both sounds stay in one pitch), in favor of other sound effects in certain THX logos.

The U.S. Patent and Trademark Office's website includes an MP3 specimen of the sound.

The sound is perceived as louder than it actually is; sound designer Gary Rydstrom

 has been quoted as saying "I like to say that the THX sound is the most widely-recognized piece of computer-generated music in the world. This may or may not be true, but it sounds cool!"

Furthermore,
The sound can be approximated vocally by two (or more) people by both starting on the same note, then each continuously diverging, one up and one down, until the same note is reached two octaves apart and then sustaining for several moments.

Prior to the creation of Deep Note, several other works made use of similar techniques of frequency spread.
