Mr. Pommes,
before you make any changes on "Sound Branding" again, please consider these facts from Google:

Nevertheless, the term „Sound“ works best in all connotations and is thus semantically most suitable as the umbrella term for everything hearable. “Audio” is also good, although it rules out anything mechanical – and is nowhere near as flexible as “sound”. “Sonic” is largely associated with the speed of sound, and the hearing of bats. Curiously enough, the term „Sonic Branding“ was „hip“ in the UK during the late 90´s but has since lost ground.--Groves Hamburg 14:24, 6 November 2006 (UTC)
