I'm having trouble figuring out where the 4/10*d comes from in the wavelength correction formula. I understand that it would make a difference what the diameter is, but would appreciate if anyone could post a good explanation. —Preceding unsigned comment added by 207.233.32.18 ( talk) 21:54, 20 March 2008 (UTC)
I don't understand how the clarinet is closed at one end, but the saxophone and oboe aren't. A saxophone is almost the same as a clarinet in the way it is played. Any insight, anyone?-- Nathan ( Talk) 17:18, 9 March 2006 (UTC)
In the equation f=nv/2L, what is the length of the string expressed in? Also, the "n"=1,2,3.. What does that mean? 71.80.171.94 22:56, 26 June 2006 (UTC)
I can't understand the following sentence, and - as it stands - it seems to have grammatical errors :
For mammals the membrane by having different resonance on either end so that high frequencies are concentrated on one end and low frequencies on the other.

I have noticed that the cones section does not have a proper reference. Does anyone have a good online citation/book to link the formula and its derivation to? fuzzywallaby ( talk) 01:54, 21 January 2011 (UTC)
f=nv/4L for a closed tube. Is this based on experimental data or is there a way to prove it? Gagueci ( talk) 23:54, 23 November 2007 (UTC)
It is unclear what the italic l, m and n represent in the equation, apart from them being described as non-negative integers.
Can someone please clarify? Jbwright ( talk) 00:16, 9 June 2009 (UTC)
I read an excerpt from Physics of Waves by William Cronk Elmore and Mark A. Heald. This is how I interpret it: l,m and n are the modes (harmonics where the fundamental =1) of waves traveling perpendicular to the dimensions of the box x,y and z. If a wave's direction of motion and a wall are parallel they do not effect each other. If all three modes are 0 than no standing wave exists. Non whole number harmonics ( Inharmonicity) tend to cancel out allowing only integers to persist. 65.80.178.227 ( talk) 08:17, 20 August 2009 (UTC)
Usually resonance in a tube is drawn with nodes at closed ends and anti-nodes at open ends. The images here are opposite to this, is this intended? 82.32.13.127 ( talk) 17:32, 10 December 2007 (UTC)
The pictures are wrong; not only at the open/closed_end side, as observed above, but also at the loudspeaker's ends, where we should find anti-nodes! The pictures show correctly that in closed tubes only odd harmonics are present (while in open tubes all are permitted) since the two errors (on the two sides of the tube) compensate. —Preceding unsigned comment added by 79.31.197.159 ( talk) 08:15, 25 March 2009 (UTC)
I agree with the comment on the images. I too, believe that they are backwards in their presentation, plus a driver (speaker) at one end changes the depiction also. A closed end is a displacement node wherein there can be no movement of the particles. It is the equivalent of a fixed end in a vibrating string. An open end acts as an anti-node for a standing wave. This is a displacement anti-node, with the reflection being equal and opposite. — Preceding unsigned comment added by Blb350 ( talk • contribs) 01:02, 1 March 2011 (UTC)
I have removed the section of this name since it didn't make any sense. The original text follows:
A musician, forming cavity resonator within mooth, may amplify and emphasize some overtones from base tone of his/her voice or instrument. This is used for overtone singing and playing on jew's harp.

It appears that there is consensus to merge this old, stale merger proposal. And some of the content in the other articles can certainly be used to improve this one, so the merger was completed. WTF? ( talk) 20:42, 11 July 2012 (UTC)

I believe this page (transferred from closed tube) should be merged with Panflute and added to the catagory of "Acoustics". Thomas Hastay ( talk) 17:55, 19 February 2008 (UTC) —Preceding unsigned comment added by Thomas Hastay ( talk • contribs) 17:52, 19 February 2008 (UTC)
The text says the closed end remains a node and the open end has the highest vibration, yet the picture shows a graph displaying just the opposite. — Preceding unsigned comment added by Lwiniarski ( talk • contribs) 03:48, 27 July 2012 (UTC)
The text defines L = length, but does not say in what unit. Meters? User:Derek — Preceding unsigned comment added by 144.74.1.208 ( talk) 17:13, 22 April 2013 (UTC)
In the equation f=nv/4(L+0.4d) it says that n represents the resonance node as an odd integer (1,3,5...) but how do you know what integer to substitute in for n when solving this equation? — Preceding unsigned comment added by Mwmclarinet ( talk • contribs) 17 November 2011
Haven't looked in detail, but in general, such equations have a set of solutions - with a different solution corresponding to each n. — Preceding

It is a little confusing that the article text talks about displacement nodes, but the graphics show pressure nodes. A pressure node is a displacement antinode. More info and diagrams at http://www.acs.psu.edu/drussell/Demos/StandingWaves/StandingWaves.html. I think the article should make this clear somewhere.
