Lecture 14 of the NPTEL course on "Noise Control in Mechanical Systems", focusses on time domain analysis of sound signals using numerical methods to calculate sound pressure, intensity, and power levels created by different sources dependent on distance. It also includes the estimation of L10, L50, and L90 noise levels from recorded data in residential and construction zones, as well as skewness and kurtosis analysis of acoustic pressure distributions.

Stay tuned as we uncover more about noise control techniques in upcoming lectures.
