SPECTRUM ANALYSIS FOR INTRODUCTORY MUSICAL ACOUSTICS

A ''real time'' fast Fourier transform spectrum analyzer facilitates s everal experiments for an introductory course in musical acoustics. Wi th its rapidly updated display, the time-dependent vibrations of an al uminum bar are easily studied, Using longer time acquisitions and corr espondingly higher resolution facilitates the study of string inharmon icities, resonant energy transfer, and sound radiation patterns in gui tar acoustics.
