Category talk:Sound

Acoustics
Should category:Acoustics remain a subcategory or vice versa or both? &mdash; Sebastian (talk) 17:40, 2005 May 18 (UTC)
 * Acoustics is currently a subcategory of Sound. Articles should not be in both. I could use some guidance as to what belongs there as opposed to what belongs here in Sound. --Kvng (talk) 21:55, 9 November 2010 (UTC)
