Abstract
Impulsive sound components in a composite sound signal are separated using wavelet analysis and sorting of wavelet coefficient sets according to statistical parameters of each respective coefficient set. Each entire coefficient set is either included or excluded from each respective separated component based on the statistical parameter. Once the impulsive sound component is isolated, it is compared with reference sound information in order to classify the sound according to its potential causes.
