All of our healing sounds work in a similar manner to approved models. In our extensive experience we believe that using healing sound as a method of improving health is through meticulous combination of the correct sounds and all of our sounds are within approved frequency range, therefore entirely safe to use. It is best to use moderate volume to avoid any damage to your healing. It is important to remember that it is the sound wave that responsible for the healing action and not the volume.
