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]
