In the audio clip you can listen to some routine activity. The sound has been post processed to bring it down to the human audible frequency range.

Id this activity.
To help matters, this sound can be detected/recorded using instruments of the kind shown in the image. This instrument has seen military applications as well, mostly for detecting sounds in its niche domain. Id the instrument.
Super-toughie, seemingly cracked _only_ by Rogi! Great job, sir!

    The sound is trees cells in trees xylem and phloem popping trying to suck water from the ground and the instrument is a Reson model TC4014 hydrophone.

    Probe Microphone.
    Application of the probe microphone method to measure attenuation of hearing protectors against high impulse sound levels. So the sound might be what happens in normal ears when a high decibel explosion happens
