Abstract: Experimental investigations into acoustic properties of building materials and structures manufactured thereof were conducted in a noise-suppression chamber. A study was made of the noise-suppression efficiency of chipped scrap tires of different crumb rubber, using the source of constant noise from loudspeakers “Bruel&Kjaer”. For experiments, crumb rubber of three different sizes was used: crumb rubber I with the size of 0.5–1 mm, II – 4 mm, and III – 6 mm. Scrap-tire crumb rubber was placed into the samples of experimental structures of thickness (50 mm), and recovered from two different sides of the building materials (gypsum boards, wood cutting boards, wood boards, metal plate, organic glass). The experimental investigation results show that the coarsest crumb rubber (6 mm) with wood cutting boards is most efficient in suppressing low-frequency sounds (up to 300 Hz), when noise level reduction gets changed in the range of 53 dB to71dB.
