Über die Lautstärke von gleichförmigen Geräuschen
With the aid of equal loudness contours (loudness in sones as parameter), of the measured width of the frequency groups and reduction of loudness in neighbouring frequency groups, the level of sustained noises with given spectra can be calculated. The aural analysis of a sound into bands of definite size (frequency groups), already demonstrated in respect of hearing threshold, masking and phase detection, appears meaningful in the investigation of noise-levels. Loudness is estimated from the sound intensity in the frequency groups, acting separately at low intensities but with considerable throttling of one group by neighbouring ones at high intensities.

- 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.
