Young's Modulus Measurement System for Wood
Using this system, a piece of wood under test is hit with a hammer, and the resulting sound is
measured with the RIONOTE Multifunction Measurement System. Young's modulus is then determined from the sound frequency and the material volume and density of the wood.
The Preamplifier NH-22A and Microphone UC-59 can be directly connected to the RIONOTE,whose light weight (only about 1.2 kg), small dimensions, and battery driven operation make it eminently portable, for easy measurement and analysis in the field. System Diagram

Using a computer, entering the fundamental frequency as determined by FFT analysis along with the specimen's dimensions and mass allows calculation of Young's modulus.
