Abstract
The acoustic chamber for the detection of insects provides for the acoustic detection of insects living within the trunk of a tree. The chamber includes an annular shell disposed around the trunk of the tree to define an annular acoustic or sound chamber. Acoustic sensors are mounted in the shell walls. The acoustic sensors may be microphones that extend from the shell to be in direct contact with the tree trunk, or microphones spaced apart from the tree trunk, or other suitable acoustic transducers. The acoustic sensors are connected to data processing equipment for analyzing sounds picked up by the sensors for acoustic signals indicative of insect infestation.
Claims20
An acoustic chamber for the detection of insects, comprising:
- a shell adapted for placement around a trunk of a tree, the shell having a segmented annular base, a plurality of shell wall members supported on the base, and an upper ring disposed on top of the shell wall members, the shell defining an annular acoustic chamber;
- and
- at least one acoustic sensor mounted on the shell, the sensor being oriented to detect sound within the annular acoustic chamber.
An acoustic chamber for the detection of insects, comprising:
- a shell adapted for placement around a trunk of a tree, the shell defining an annular sound chamber surrounding the trunk of the tree;
- means for insulating the sound chamber from sound emanating below the shell;
- means for insulating the sound chamber from sound emanating above the shell;
- at least one acoustic sensor mounted on the shell facing the sound chamber, the sensor generating a signal in response to sounds produced by insect activity within the trunk of the tree;
- and
- a data processing system electrically connected to said at least one acoustic sensor, the data processing system having means for comparing the signal generated by the at least one acoustic sensor to sound signatures corresponding to activities of pestiferous insects in order to detect insect pests within the trunk of the tree.
