Influence of Technical Parameters on Sound Absorption of Straw Board

Introduction In architecture environment, no matter how to create the fine acoustic quality or control the noise, we both need to know and grasp the acoustics characteristic property of material and their structure. In the past people often emphasize on the sound vibration characteristics and dynamic elastic modulus of timber and wood materials. At present, there is little study on sound absorption property o~ wood and other bio-basod material. Belong to this, the paper attempt to discuss the sound absorption property of straw board in different hot press technics. The acoustic properties of wood and wood materials is judged by its acoustic absorption coefficient, the paper measure acoustic absorption coefficient of light straw board through standing wave tube to investigate the sound absorption properties.
