Feedback form is now closed.
The equal energy hypothesis has been shown to be inadequate for describing the risk of hearing impairment due to impulsive noise exposure.  Sound pressure level can be interpreted as the amount of sound energy.  Kurtosis level can be interpreted as the type of sound energy.  By using a proposed signal processing methodology both the sound pressure level and kurtosis level can be calculated with the same optimized time-frequency resolution.  This provides more information to describe the distribution of the sound pressure time waveform.  Results from the analysis of datasets of continuous and impulsive noises will be presented.
