Title Direct measurement of sound intensity, an efficient method for acoustic measurement in ventilation and air conditioning techniques
Original title Die direkte Messung der Schallintensität - ein leistungsfähiges Verfahren für akustische Messungen in der Lüftungs- und Klimatechnik [in German]
Bibliographic information 1980, Vol.16, No.2, p.98-100. Illus. 6 ref.
Abstract Description of a method enabling sound intensity in ventilation installations and ducts to be measured by means of 2 ordinary pressure-type microphones. The method is based on the Schultz and Pavić techniques, using numerical frequency analysers for acoustic signal analysis. The advantage of this 2-microphone technique is stressed as regards the influence of the stationary wave and pseudo-noise.
