Abstract

A new inorganic sound-absorbing material is proposed with the background of the subways reduce the noise pollution by grouting behind the track wall. By using the standing wave tube method, we investigate the sound absorption coefficients of this new inorganic sound-absorbing material with water cement ratios of 3.0, 4.0, 5.0 and 6.0. The results show that: when the water cement ratio is 5.0 and the frequency is 1250Hz, the sound absorption coefficient reaches 0.53; when the water-cement ratios are 6.0 and 4.0 and the frequency is 3150Hz, the sound absorption coefficients also reach more than 0.5. The average sound absorption coefficient and noise reduction coefficient of the new inorganic sound-absorbing material reach more than 0.2 in the frequency range of 20-4000Hz. This material has sound absorption performance and the best sound absorption effect is achieved when the water-water ratio is 4.0.
