This system samples the\u003cbr\u003enoise right at your ear, reverses it 180 degrees, and\u003cbr\u003eplays it back to actively cancel the noise.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eWhat frequency range is the ANR most effective?\u003c\/strong\u003e From 50-1000Hx, where most prop blast,\u003cbr\u003eengine noise, and wind noise is located.\u003cbr\u003eWhat is the standard power source?
