Paper Abstract

Short, high frequency bursts are found in flow noise data from a transient regime in a pipe flow experiment. These bursts are directly detectable in accelerometer measurements, but processing is necessary to detect them in synchronous hydroacoustic measurements. These signals can be detected and recovered using wavelet thresholding. New variations on methods of choosing the threshold and exploiting translations of the wavelet basis are described, then applied to the estimation of these bursts.
