Abstract
<p>The acoustic emission (AE) techniques are utilized to investigate a drought-induced plant's stress in its physiological phenomena. Plants emit AE caused by the cavitation. Discriminant between the burst-type AE caused by cavitation and the co-occurring other AE waves has been needed to achieve the practical use of AE applications. In this paper, the burst-type AE is discriminated among four types of detected waves by wavelet transformation's parameter and the frequency estimated by the Rayleigh-Plesset equation. The burst-type AE was discriminated from the others in high accuracy by the centroid time, the centroid frequency and the signal intensity rate calculated by wavelet transformation and the frequency based on the Rayleigh-Plesset equation.</p>
