Sound Image[edit]

I'd like to see a portion regarding "sound image". You hear a lot of description of a soundfield in/as an image (I think I might have seen mention of it in the 8-track tape listing), but there is no reference to its definition anywhere that I've found in Wikipedia. It is a very important aspect of any work done by professional audio artists, producers, and technicians. Photoactivist (talk) 21:11, 18 May 2011 (UTC)

Stereo imaging is probably what you are looking for. I've added a link to See also. --Kvng (talk) 14:31, 21 May 2011 (UTC)

Philosophy of Sound[edit]

It says at the front of the page that Sound is a mechanical wave, etc. My question is: does sound really exist in reality or does it come into being when it affects the eardrum to produce sound in the brain? Perhaps the article should say that sound is a sensory perception created by neuro-chemical signals caused by this mechanical wave, etc. — Preceding unsigned comment added by 65.96.4.72 (talk) 15:17, 10 July 2011 (UTC)

Sound it exists as a mechanical wave or pressure wave even if no one is listening. --Kvng (talk) 14:13, 12 July 2011 (UTC)

Edit request on 5 January 2012[edit]

First paragraph refers to "compressible media" water is not compressible...see hydrostatic testing. Suggest removing word compressible, sound does move through mediums, space is a vacuum and is the absence of a media, therefore sound does not propagate through space.

65.175.162.111 (talk) 23:29, 5 January 2012 (UTC)

Sound moves through water by compression waves, the same way it moves through air and to some extend through solids. And "media" is the plural of "medium"; yes, sound needs a medium, and won't propagate through a vacuum. Dicklyon (talk) 23:36, 5 January 2012 (UTC)
Not done: please establish a consensus for this alteration before using the {{edit semi-protected}} template. Mato (talk) 17:21, 11 January 2012 (UTC)

There is no such thing as sound waves. Lets imagine in the best Einstein tradition that a tree falls in a forest, 45 tons of Redwood crash to the ground. In doing so it will disturb the air around it and setup frequencies of disturbed air - which will travel out multi directionally. There is no noise. On reaching our ear (or the ear of any mammal for that matter) the disturbances of air travel down our ear cavity and strike our eardrum, or tympanic membrane (probobly the most complex peice of tissue in our body). These vibrations are amplified by 3 small bones; one end of the first bone being connected from the innner ear side of the membrane - to the mebrane, and the end of the third bone to an 'elasticky' plug at the opening of the cochlea. The cochlea is filled with a viscous substance a bit like olive oil and the amplified vibrations from the 3 bones couse the viscous substance to vibrate at various frequencies which are picked up by hairlike receptors connected to the the brain which converts these vibration into what we know as sound. — Preceding unsigned comment added by 2.96.115.141 (talk) 09:12, 25 February 2012 (UTC)

Speed of Sound[edit]

The speed of sound at sea level is also expressible as 1125.3281 feet/sec, as many use it. Audio engineers and recording people are still comfortable working in feet/sec, and that number should be included paranthetically in the sectoin of the same name in this article. 99.2.69.235 (talk) 09:05, 28 February 2012 (UTC)

Sound Can Travel Through Vacuum?[edit]

I know it's what we all learned in High School, but apparently new research has proven otherwise. Maybe it's just quackery? Someone more expert on these matters ought to take a look. 67.41.68.211 (talk) 09:18, 15 March 2012 (UTC)

The article does not say that sound can travel through a vacuum. Instead, it says that if you have a piezo-electric material and sound waves hit it, the sound waves can mechanically excite the material, which then creates electromagnetic waves. It is those waves that then cross the vacuum gap. --MichiHenning (talk) 22:37, 10 May 2012 (UTC)

Edit request on 10 May 2012[edit]

Sound intensity link should point to Sound intensity rather than Intensity (physics), since there is a specific page for that. Gozzilli (talk) 09:26, 10 May 2012 (UTC)

Seems reasonable, Done. Monty845 05:07, 14 May 2012 (UTC)

Over-linking[edit]

This article appears to be extensively over-linked (WP:OVERLINK. There are many links (such as pressure, density, species, mammals, etc.) Any links that do not directly relate to the topic or reference commonly understood terms should be removed. --MichiHenning (talk) 22:36, 10 May 2012 (UTC)

Grammar Edit[edit]

The line "Other species have a different range of hearing" needs to become "Other species have different ranges of hearing" because the various species have different respective ranges of hearing and not just one single range. This is just a simple edit that I thought someone should change.

If a tree falls in the forest and no one is around to hear it does it make a sound?[edit]

If a tree falls in the forest and no one is around to hear it does it make a sound? — Malikis2cool (talk) 02:38, 28 March 2013 (UTC)

If a man speaks and there is no woman to hear him, is he still wrong?
MichiHenning (talk) 21:57, 2 June 2013 (UTC)


These are good questions, in earnest, and they illustrate that the concept of sound is not just a concept of mechanical disturbances propagated in matter, but is directly connected with the perception or sensation of these disturbances in the ear. Already by 1900 this duality of the definition of sound was recognized and should be represented in the article. Kbrose (talk) 21:28, 12 June 2013 (UTC)
The definition in this article does not require a human to hear it, only that it has frequencies that a human could hear.
How do you know that a tree has fallen in a forest? QuentinUK (talk) 01:46, 21 January 2014 (UTC)
