> Does anyone have any idea about this parabolic microphone? > http://www.oomagamma.com/parabolic/parabolic.html Now this one puzzles me. The five elements of the array include the vertical dimension so how is this handled and reproduced? The prime focus of a parabola is level with the point where the profile reaches 45 deg. The array seems to be at about twice this distance so sounds reflecting off the outer parts of the dish will miss the mic array. The graph on the web site is of ocean temperatures so it looks like "work in progress". David David Brinicombe North Devon, UK Cogito cogito ergo cogito sum - Ambrose Bierce |
