Abstract
We apply time-frequency analysis to various acoustic transients. Estimates of the conditional mean frequency and the conditional bandwidth exhibit characteristic trends for different transients. This information may be helpful in distinguishing between different classes of transients, and in understanding the underlying mechanisms generating the transient
