We already anticipated that.Okay
1) two pics
2) The aim of the work is to measure weak sound amplitudes of an ultrasonic source using a MEMS microphone. An amplifier adapted to the microphone is to attenuate sound frequencies up to 65 kHz, so that higher sound frequencies can be amplified by another. In summary, this work is intended to act as a validation platform for ultrasonic pulses.
3) I'm in the univeristy 5 semester.
That adds nothing new.The aim of the work is to measure weak sound amplitudes of an ultrasonic source using a MEMS microphone.

Next question,Echo sounding in air meets the topic quite well
Well then you have lost me.I'm so sorry its not echo sounding i only mess the ultrasound in the air of the transmitter. There is no special reason or function. I have only transmitter and receiver. No object.
