Abstract

406,384. Nonconducting coverings for sound. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Amy, Aceves, & King, Inc. ; 55, West 42nd Street, New York, U.S.A.) Sept. 3, 1932, No. 24638. [Class 64 (ii).] Sound-absorbing structures for rooms are formed with a number of separated small diameter tubular passages with rough surfaces, one end of which at least is open to the atmosphere, and of such a length that the tubes resonate to the frequency of the lowest note it is intended to suppress. As shown, the apparatus may take the form of bricks or ornaments and the separate bricks may be used to form a wall. The devices are formed with a shell or container 1 packed with corrugated cardboard forming narrow apertured tubular spaces 2 having fuzzy or rough inner and outer surfaces, and it is stated that, if the tubular passages are long with respect to the wave length and small in diameter in comparison with one-fourth the wave length, they absorb a considerable band of higher audible frequencies also ; but at frequencies less than the resonating frequency, the portion of sound absorbed is practically negligible. The device may be formed of tubular passages having varying lengths to suppress sounds of various frequencies.
