Abstract
Exemplary embodiments of a handheld probe (HHP) of an Acoustic pulse reflectometry (APR) system are disclosed. Embodiments of the HHP can comprise a loudspeaker and microphone that are vibration isolated from each other and from the tube under test. In some embodiments the microphone can be isolated from the housing of the HHP. In other embodiments the housing of the HHP can be isolated from the loudspeaker. In another embodiment the housing of the probe can be isolated from the tube under test. Yet, some embodiments combine all of this isolation options. In such embodiment the loudspeaker is isolated from the housing, the housing is isolated from the tube under test, and the microphone is isolated from the housing, and so on. Isolation can be achieved by using materials that absorb vibration, material such as but not limited to rubber, foam, silicone, etc.
