We have started research on an infrasound microphone with an unusual design. A special feature of our idea is the assumption that the lower limit frequency should be zero (!). The first tests on the device model have already confirmed that we have fulfilled the assumption. Such microphones, in different variants (eg in the form of a geophone) can be useful in physical research, e.g. in seismometry.

Now, if will possible, we will work on the sensitivity of the microphone.We started the project ourselves, so the further progress of the work will depend on whether we find entities interested in the subject and willing to finance further research.


You can measure
