I am working on a project; detecting the sounds made by pests in stored grain while eating. I know that the ultrasonic disturbances occur when the pests tear the materials during feeding.
I need a microphone that can detect these 'ultrasounds'. I will connect the microphone directly to a PC and carry out the frequency extraction in National Instruments' Lab-View software. I searched and found that the Panasonic wm-61a and Primo em-172 can detect ultrasonic frequencies. Can I use them? Or are there any other alternatives?
Also please elaborate if I require anything else to detect ultrasonic frequencies. I am new to this and any help would be hugely appreciated.
