Talk:Mel scale

Mel and Hz

How can mel and Hz coincide below 500 Hz, and not above, when 1000 mel is defined as 1000 Hz? Maybe it is meant that below 500 Hz the relationship is linear? Guaka 17:49, 20 Aug 2003 (UTC)

2595 and 1227

Many authors say: Mel = 2595*log (1+f/700) .. where does this 1227.something in this article come from??

1127.01048 is for natural logarithms (see below). 2595.03753 is for logarithms to base 10. --Zundark 15:33, 21 Sep 2004 (UTC)

1127.01048

Where does 1127.01048 come from? (Maybe that's what the previous poster to this page meant?) Michael Hardy 01:40, 21 Sep 2004 (UTC)

It's supposed to be 1000/log(17/7), so that m = 1000 corresponds to f = 1000. --Zundark 15:33, 21 Sep 2004 (UTC)

"Mel"?

What does 'mel' stand for? Shoud imho be mentioned in the article. Sipalius 13:07, 5 Mar 2005 (UTC)

Mel is a short from word melody.

In other words...

"In other words," ... what? Is this an accidental deletion?

I don't get it

What does it mean that two pairs of pitches are judged by listeners to be equal in distance from one another? For me C and C# are always a half-tone apart, no matter in what octave. Is this about the granularity of hearing, ie how small a pitch difference we can recognize?--87.162.56.49 (talk) 00:08, 23 September 2008 (UTC)

The psychoacoustics article implies that you are right. It implies that the mel scale is calibrated such that the number of mels between one tone and another tone with a just-noticeable difference in frequency (in a typical human ear) is constant throughout the audible frequency spectrum. But how many mels is just noticeable? 10 mel? 1 mel? 0.01 mel? --68.0.124.33 (talk) 13:46, 15 October 2009 (UTC)

We had a long discussion, with sources, about the mel scale on the auditory list. You can jump into the middle and get some answers here. Dicklyon (talk) 15:52, 15 October 2009 (UTC)

Incorrect Link

The link to Newman in the first sentence is to the wrong Newman. I'm assuming (but not with complete certainty) that the correct Newman is Robert Newman who with Bolt and Beranek, founded Bolt, Beranek and Newman, latterly known as BBN. There is no wiki entry on Robert Newman but there is one for BBN.

The paper says E. B. Newman, so not Robert. Just unlink it. Dicklyon (talk) 23:25, 18 January 2013 (UTC)

I verified the name and middle initial, Edwin B. Newman, of Swarthmore College, removed the link and updated the URL. Dicklyon (talk) 23:32, 18 January 2013 (UTC)
