In an earlier paper formulae for the variance of the decay rate of a band of noise in a reverberation room were derived. In this paper similar formulae for the variance of the decay rate of a multitone in a reverberation room are derived.


In einer früheren Arbeit wurden bereits Formeln für die Varianz der Nachhallkurvensteigungen von Bandpaßrauschen im Hallraum abgeleitet. In der vorliegenden Arbeit werden ähnliche Formeln für die Varianz der Nachhallkurvensteigungen im Hallraum bei Anregung durch eine Reihe verschiedener Einzeltöne hergeleitet.


Dans un article précédent on avait établi des formules donnant la variance du taux de décroissance d'un bruit de bande dans une salle réverbérante. Des formules similaires sont établies ici pour la variance du taux d'extinction d'un son complexe formé d'un certain nombre de sons purs.

  • Acta Acustica united with Acustica, published together with the European Acoustics Association (EAA), is an international, peer-reviewed journal on acoustics. It publishes original articles on all subjects in the field of acoustics, such as general linear acoustics, nonlinear acoustics, macrosonics, flow acoustics, atmospheric sound, underwater sound, ultrasonics, physical acoustics, structural acoustics, noise control, active control, environmental noise, building acoustics, room acoustics, acoustic materials, acoustic signal processing, computational and numerical acoustics, hearing, audiology and psychoacoustics, speech, musical acoustics, electroacoustics, auditory quality of systems. It reports on original scientific research in acoustics and on engineering applications. The journal considers scientific papers, technical and applied papers, book reviews, short communications, doctoral thesis abstracts, etc. In irregular intervals also special issues and review articles are published.
