Definitvely not, Robin. there is often confusion with the 3 dB, because 2 added Audio Signals with the same dB level will result in a 3 dB higher level. But two same siganls do not result in doubling of loudness, a fact that was already known by the organ makers. Also 2 strings do not sound as double as one, it raise only ~ to1.3 of loudness level. Sometimes you find tables where 10 dB is double loudness, that is due to a investigation in the fifties done by Stephens. In later investigations (Warren, 1970) has been found that loudness doubling is about the 6 dB. But this is also somewhat frequency dependent. more info at: http://www.personal.rdg.ac.uk/~syswatkn/ap3.pdf Regards, Bernhard ----- Original Message ----- From: "Robin Hufford" <hufford1@airmail.net> To: "Pianotech" <pianotech@ptg.org> Sent: Wednesday, January 14, 2004 9:43 AM Subject: Re: Software questions MiniMens > Actually, I believe 3 Db is about a doubling of "loudness". 3 is a > doubling plus 3 more makes a quadrupling plus 3 more makes eightfold at > 9 Db.
