I have created a similar stub under "Sound mirrors", before discovering this article. Should we merge them and redirect one of the headings? Please leave a message in the discussion area for "sound mirrors", where I am more likely to see it.
- Sound mirrors should be redirected here. Acoustic mirror is the correct term and its article contains more useful info. --Lancevortex 11:07, 30 May 2005 (UTC)
This may be technically accurate (no source given), but the generally-used term is "sound mirrors": Google gives 13,400,000 hits as opposed to 1,150,000; I live in the area of Kent where most are to be found and have never seen or heard them referred to other than as "sound mirrors".
Addition to be merged into article
User:184.108.40.206 added these comments to the page. They need to be reworded and merged into the article. I will do it when I get the chance, if no-one beats me to it. I have already corrected the spherical/parabolic reflector anomaly. --Lancevortex 18:11, 15 Jun 2005 (UTC)
- I have no idea how to edit this page - but I thought you ought to change this: The sound mirrors are not parabolic as is stated but in fact hemispherical mirrors and that is their genius, because in addition to being able to detect range (over 20 miles on a good day), they could also detect direction.
- What the sound mirrors gave us was the methodology by which to use interconnected stations to pin point the position of an enemy in the sky. The system developed by the sound mirror team (lead by Dr Tucker)for linking the ranging stations together and plotting aircraft movements by using more than one station was given to the early radar team and lead to their success in WW2. As is noted elsewhere on wikipedia, the British radar was less sophisticated than the German system, yet ours was used more successfully, and that is because of all the work done by the totally unheralded sound mirror team.
User:Ema Zee has these comments:
- Acoustic locator is the meta term to acoustic mirror. Take the Japanese War Tuba. This class of acoustic locator is essentially a giant earhorn, and is not a mirror at all. If anything, acoustic mirror should be included under Acoustic location or locator, in it's own subsection for the appropriate class of technology
- That's correct. There are many acoustic location devices that aren't acoustic mirrors. --John Nagle 17:20, 11 April 2006 (UTC)
--Ruthe (talk) 22:00, 8 April 2014 (UTC) The sound mirror at Kilnsea on Spurn Point on the peninsular of land forming the end part of the north shore of the Humber Estuary was installed during WW 1, not WW 2. It was used to determine the direction of approaching German Zeppelins. This is confirmed by the reference to a BBC page at BBC News Humberside and also the Wikipedia page at Kilnsea. I suggest this page should be amended to include a section explaining the first use of these "Sound Mirrors" in WW 1.
The preamble menitons the amplification of sound waves. Can they be amlified in the way similar to that of the optical waves? If there exist any Sound Amlification by Stimulated Emission, and how is it called? dima (talk) 22:59, 7 April 2008 (UTC)
The last paragraph confusing to me. It says the following:
"Parabolic microphones appear to use acoustic mirror properties but instead depend on a parabolic dish to reflect sound coming from a specific direction into the microphone placed at the focus."
That description pretty accurately describes a parabolic acoustic mirror. The main ones in the article use hemispherical dishes, but the novelty dishes mentioned later are parabolic. Is there some other characteristic that makes parabolic microphones *not* acoustic mirrors? I mean, the main acoustic mirrors in the article (concrete ones) even had mics at the focus. --The Human Spellchecker (talk) 23:07, 17 January 2011 (UTC)
- Perhaps the parabolic microphone description can be changed to encompass the fact that it is handheld, lightweight and very mobile. Binksternet (talk) 23:37, 17 January 2011 (UTC)
Whispering galleries - merge?
Is the whispering gallery page sufficiently similar in concept that it should be merged into this one? I'm not totally convinced; but I do think that the pages should contain links to each other. Anyone? Quickos (talk) 19:48, 10 February 2011 (UTC)
