Abstract:
An arrangement for monitoring a noise signal that has a temperature-responsive noise signal amplitude characteristic and that is issued by an energy transfer system while the energy transfer system is subjected to a test process, the energy transfer system being of the type having an energy input and at least one energy output, the arrangement comprising:a base supporting the arrangement and the energy transfer system; an isolation support supporting the energy transfer system whereby the energy transfer system is translatable in at least one plane of freedom with respect to said base; an engagement arrangement securing the energy transfer system to said isolation support; a first acoustic sensor arranged at a first location for producing a first sensor signal responsive to a qualitative condition of the energy transfer system, the sensor signal having an amplitude characteristic; a thermal sensor producing a thermal signal responsive to a temperature of the energy transfer system; and an acoustic sensor sensitivity controller responsive to said thermal sensor for controlling the amplitude characteristic of the first sensor signal in response to temperature.
