ABSTRACT:
Apparatus and method of measuring acoustic properties of a drumhead of a drum are disclosed. The acoustic properties are measured by exciting the drumhead with a source of energy and detecting the acoustic energy emitted by the drumhead. The acoustic energy emitted by the drumhead may be measured using a microphone or other acoustic sensor. The use of multiple energy sources provides isolation of acoustic energy and allows measurement of local resonance of the drumhead.
