Popis: | It is not possible to apply nearfield acoustic holography (NAH) for the acoustic field composed of reflected waves. To apply NAH properly it is necessary to separate incoming and outgoing waves. In order to identify noise sources in enclosures using NAH a technique for such separation is required. In this work a new technique involving analysis of acoustic pressure on two parallel planes near a noise source is presented and tested by using a speaker. |
