abstract = "The study applied small-perforated manufacture to ABS panel. The module design and injection molding would produce special pattern on surface of small-perforated ABS panel. The hole is formed by V type cannelure, which is on different side of panel and with direction in perpendicular.
In this form, the holes would be in the cannelure instead on the surface of panel, and also have extremely minuteness depth (about 1 mm) and diameter with 0.25 mm. This particular form of holes would occur sound damping effect and increase the absorption of panels. The sound absorption coefficient
above 1250 Hz of single small-perforated ABS panel would reach to 0.4, and in further the value above 250 Hz of the panel back with 20 cm air layer would reach to 0.3. This outcome indicates the small-perforated form would make the ABS panels provide functional sound absorbing effects. In
additional, the surface of ABS panel would match suitable appearance for different interior demands by spray printing. As the results, the small-perforated manufacture and flexible appearance of ABS panels would bring new development for the absorbing materials application.",
