> It can if it sets up a resonance, especially in a large cavity like the chest. That will set up displacement amplitudes in body parts such as the sternum, trachea, and lungs, which are much greater than an SPL reading would convey. From there anything can happen as it involves critical nervous system components and whatever it is they're controlling, like heart rhythm.

One of the developers of the French system ended up getting paralysed by his invention. It is completely useless for military purposes because such low frequencies cannot be directed at a target with any precision without the source being enormous and therefore easy to detect and destroy by more conventional methods. Low-frequency noise from wind turbines is a problem in some places because the sound can be very annoying. Beyond that, the effects will be negligible. John
