The MPM system measures the Young's E modulus
and the loss factor of raw material used for loudspeake design. The
vibration beam technique is modified to be capable for measuring of also
soft materials such as thin foils of plastic, rubber and any kind of paper
and impregnated fabric. After cutting 1 cm strips the probes are clamped on
one side and excited pneumatically by using the suspension part measurement
bench and special accessories and software. Start a movie
here and see how to handle the MPM system.
