Apparatus for detecting the breaking of a contact-sensitive surface includes an acoustic, shock, and vibration transducer, a detector circuit responsive to the transducer for detecting an acoustic wave resulting from a contact force applied to the surface and generating a signal, a support for the transducer, and the means for disqualifying a contact force to the support as a breakage event that relies on differentiation of the speed with which a shock wave travels through a solid material versus the speed with which an acoustic wave travels through air. The transducer may include a front electret condenser microphone and in some preferred embodiments the microphone does not have a preamplifier associated therewith. The invention also includes the method for detecting the breaking of a contact-sensitive surface that includes providing an acoustic, shock, and vibration transducer, providing a support for the transducer, providing a detector circuit responsive to the transducer for detecting an acoustic wave resulting from a contact force applied to the surface and generating a signal; and providing means for disqualifying a contact force to the support as a breakage event that relies on differentiation of the speed with which a shock wave travels through a solid material versus the speed with which an acoustic wave travels through air.
