From subjective tests in a synthetic sound field it was found for both, music and speech, that the loudness in rooms increases with the reflexions, independently of the delay-time after the direct sound. On the basis of these results and hitherto existing proposals a measure for room induced amplification (Raumverstärkungsmaß) is proposed.


Durch subjektive Tests in einem synthetischen Schallfeld wurde ermittelt, daß, sowohl bei Musik als auch bei Sprache alle im Raum nach dem Direktschall eintreffenden Reflexionen den Lautstärkeeindruck erhöhen. Davon ausgehend wurden bisherige Vorschläge für ein objektives Kriterium zur Erfassung von Lautstärkeverhältnissen zu einem ,,Raumverstärkungsmaß“ zusammengefaßt.


On a effectué des tests subjectifs dans un champ sonore synthétique avec signaux de musique et de parole: dans tous les cas, on a observé que la sonie était renforcée par les réflexions, tout à fait indepéndamment du retard entre ondes réfléchies et onde directe. Compte tenu de diverses propositions antérieures, ces résultats conduisent à un critère objectif pouvant servir de base à une technique de mesure d'un facteur spécifique et bien défini: l'amplification d'enceint.
