Test Cards are usually accompanied by some form of audio, like library music, audio tones (usually 1000 hz), or (if the company owned a radio station) radio music found on a radio station.

Some channels like Poland's TVP don't broadcast testcard music. But it was during 1985-1997 with the music from 27 CD's given by a Polish music company, AAA. TVP also own its radio Polskie Radio but never used on testcard.
