Abstract

Es wird eine Lösung angegeben, wie die Wiedergabevorrichtung für Schallereignisse so ausgelegt werden kann, daß der Diffusschall am Hörort eine gleichmäßige, frequenzunabhängige Lautheit hervorruft. Das wird dadurch erreicht, daß das dem Schallwandlersystem zugeführte NF-Signal derart verzerrt wird, daß der Diffusschall am Hörort den gleichen Lautheitsverlauf aufweist, den ein mit nicht verzerrtem NF-Signal betriebener Schallwandler im schalltoten Raum aufweisen würde. A solution is given, like that Playback device designed for sound events can be that the diffuse sound at the listening location uniform, frequency-independent loudness. This is achieved in that the Sound transducer system supplied LF signal so distorted is that the diffuse sound at the listening location is the same Loudness curve that the one with non-distorted LF signal operated sound transducer in anechoic room would have.
