木竹材声学振动特性研究进展

Research Progress on the Acoustic Vibration Performance of Wood and Bamboo

木材声学振动特性科学机理与评价方法的研究正逐渐兴起,而针对竹材声学振动特性的相关研究则少有报道。文中重点围绕木竹材声学振动特性,从声振动效率、音色和发音效果稳定性3个方面介绍了木竹材声学振动特性的定量评价方法;从不同尺度(宏观-微观)、不同层次(化学组分-物理性质)和不同方式(选材-加工)系统阐述其主要影响因素;在此基础上,总结了木竹材声学特性功能性改良的主要方法,并提出今后科学研究的具体建议。

The research on the mechanism and evaluation method of wood acoustic vibration performances(AVP)is gradually rising.However,few studies on bamboo AVP were reported.In this paper,both wood and bamboo AVP were reviewed.A serials of quantitative evaluation methods of acoustic vibration efficiency,tone,and pronunciation effect stability were introduced.The main influence factors of AVP were analyzed at different levels from macro to micro,and the effects of chemical components,physical properties,as well as processing methods on AVP were also discussed.On this basis,the methods used for wood and bamboo AVP functional improvement were systematically summarized.Some specific suggestions for future scientific research on the wood and bamboo AVP were also given.
