Determination of acoustic performance of tire-fluff and gypsum/tire-fluff boards by measurements in acoustic chambers

Original language description

An increasing number of end-of-life tires is becoming a global issue that requires finding new ways of recycling and recovery of tire-related waste. In the Czech Republic, about 70 thousand tons of end-of-life tires were recollected in 2019. They were mainly stored, or alternatively reused in the raw or processed state in various ways, such as an alternative fuel for cement works, or within the production of asphalt and cementitious materials. With respect to an expected increase of waste tires, the processed waste can find other meaningful applications, such as utilization in construction elements with good acoustic performance. The paper is focused on the acoustic characterization of two types of boards based on tire waste. Acoustic experiments of tire-fluff and sandwich gypsum/tire-fluff boards were performed in the system of the small acoustic chambers designed for fast comparison of acoustic insulation ability of construction elements. The noise reduction index was determined with respect to a small volume of the receiving chamber in the frequency range of 315 Hz – 5 kHz, 1/3 octave resolution, by using an 85 dB sound pressure level in the transmitting chamber. The average noise reduction index of tire-fluff board in the studied frequency spectrum was 54.1 dB which was a 14.6 dB improvement compared to the tire-fluff board.
