摘要
A method and apparatus for detecting degradation in wood by applying acoustic waves along the wood grain and measuring the bandwidths and frequencies or standing wave resonances induced in the wood as the frequency of the applied waves is varied. Good quality wood exhibits a substantially harmonic relationship between the frequencies at which resonances occur and the bandwidths of the resonances are relatively small.
