Is there any place where they do subsonic research?

While on this subject, Phono-seismology is a new name coined by Mauro Mariotti and Andrea Cellini in April 1999 when they started to catalogue noises recorded by their seismic station. The method proposes an organolectic description of the seismic signal recorded by a seismometer or accelerometer. The method is based on the high speed playback of seismic signals recorded in digital media so that they become understandable by the human ear. The seismic signals are about a few Hz (oscillation per second) and cannot be heard until the frequency has been shifted to at least 30-50Hz. Some subsonic signals are perceived by animals like cats and dogs. Very often animals become very agitated just before an earthquake. We don't know at moment if animals are excited by mechanical vibrations, by electromagnetic fluctuations, or by other natural phenomena. The fact remains that the acoustic deficiency of the human ear below certain frequency can be improved using this method of seismic acceleration and allows the ear to detect the strange patterns occurring just before and after a quake, with a retrospective analysis. Amazing!

As regards reseach programs, here are some institutes which have the facilities for conducting subsonic researches-

Subsonic weapons research is carried out by the CIA and NSA.

google "infrasonics" and you will find lots of stuff online on this. Subsonic generally means "below the speed of sound."

yes, you can create
