Dear Colleagues,
I am studying ultrasonic response of plants to human interaction. I need help determining the device I can use to detect ultrasonic sound range from 20-120 khz. The Khait et al study of 2023 showed that plants as tomato, tobacco emits ultrasonic popping noises of that range and can produce noise upto +_ 65 dbspl under stresses. I am not an acoustic guy so I need help determining what devices I can use to detect ultrasonic noise of that range?
The simplest and cheapest solution would be to use bat detector. There are many available on the market. I don't know, if they are sufficiently sensitive for such application. Other possibility is to use suitable microphone, amplifier and a scope (or ADC board) able to record signals for a long time. It will be probably necessary to isolate the plant from surrounding sound sources, that can be eventually difficult, but could be eliminated by using many microphones and create a kind of directional antenna.
