Lecture 26 of the NPTEL course on "Noise Control in Mechanical Systems", covers key principles in acoustical measurements, including the example of waterfall spectrum (time-frequency analysis), and discrete acoustic signals. It also explores the Nyquist-Shannon sampling theorem, aliasing, and measurement standards for machinery noise.

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