摘要： An expansion-molded article (foamed body) produced by using foamed and expanded beads, and having open voids has sound absorbing qualities, and can be used as a sound absorbing material. However, a sound absorbing material comprising such an expansion-molded article has been unable to attain a high sound absorption coefficient in a wide acoustic frequency range. The invention relates to a molded article produced by using resin particles, and having sound absorbing qualities. The resin particles used have through hole(s) and a porosity of 45 to 80% in a most densely packed state. The void content of the molded article is 10 to 60%, and the bulk density thereof is 0.01 to 0.6 g/cm3. The molded article has not less than 3 continuous center frequency measuring points at which the sound absorption coefficient is at least 70%, and not less than 7 continuous center frequency measuring points at which the sound absorption coefficient is at least 50% in the sound absorption coefficients at the center frequencies of 250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500 and 3150 (Hz) as determined by the measuring method of reverberant absorption coefficient prescribed in JIS A 1409.

An aliphatic hydrocarbon and/or an alicyclic hydrocarbon and carbon dioxide are used in admixture as the foaming agent in amounts satisfying the following equations (1) and (2) at the same time:E/7+0.3.ltoreq.3x+2y.ltoreq.E/7+5.4 (1)5.4.times.10.sup.-3 .ltoreq.x/(yE) (2)in which:x: the number of mols of the aliphatic hydrocarbon and/or the alicyclic hydrocarbon per 1000 g of the resin particles;y: the number of mols of carbon dioxide per 1000 g of the resin particles; andE: an intended bulk expansion ratio for the foamed particles,with the proviso that x and y are greater than 0.
