[57] ABSTRACT
A resonator assembly adapted for use with a signal detection instrument includes a sensor operative to detect airborne sound signals and a touch rod. The resonator assembly operates to convert sound signals traveling within the touch rod into the airborne sound signals for detection by the sensor and comprises a mount adapted to interconnect the signal detection instrument and the touch rod, a flexible resonator element, and a stem interconnecting the mount and the resonator element so that, when the touch rod is secured to the mount and the mount is secured to the signal detection instrument thereby positioning the resonator element relative to the sensor, the resonator element operates to convert the sound signals traveling within the touch rod into the airborne sound signals for detection by the sensor. A touch probe resonator is also provided for converting sound signals traveling in a first medium into sound signals traveling in a second medium for detection by a sensor. The touch probe resonator broadly comprises a mount, an elongated touch rod and a resonator element. A signal detection instrument is also provided for monitoring input sound signals having frequencies over a selected range and for producing output in response thereto. The signal detection instrument comprises a housing, processing circuitry, an output device and a sensor assembly which includes an elongated touch rod, a resonator assembly and a sensor.
