This article is an unfortunate example of the iHorizon. Noise canceling microphones have been around since the 1950's and are used in many applications, and they don't use two microphones. I will try to summarize this in the next days. Altaphon (talk) 21:21, 29 November 2008 (UTC)[reply]

Examples of both types exist as stated in the article. The primary advantage of the 2 mic design is that the degree of noise cancellation can be adjustable (also different filter characteristics can be applied). 86.161.56.74 (talk) 07:16, 19 July 2011 (UTC)[reply]

Why is there a reference to iPhone 4?? —Preceding unsigned comment added by 91.67.138.168 (talk) 10:51, 29 November 2010 (UTC)[reply]

The iPhone 4 discussion page has a claim suggesting that one of the 2 microphones is noise cancelling. I am currently unconvinced, but someone may dig up a citation. 86.163.87.193 (talk) 15:44, 20 July 2011 (UTC)[reply]

Not written for general readership

The 'technical details' section starts:

'The development is a special case of the differential microphone topology most commonly used to achieve directionality.'

This is the second sentence in the article but it will be incomprehensible to most readers. I don't know enough about this subject to rewrite it with confidence. The rest of the paragraph is better but still needs work. Please could someone have a go?

I'm also not sure about the use of the word 'topology'. Topology is the branch of maths where distance doesn't matter, but in designing these microphones distance (eg of ports from each other and from the diaphragm) 'does' matter...I think!
