white noise Explanation: The sound produced by a masker is normally NOT white noise, though it could theoretically be. A masker can produce the sound from waves, a fan, birds or whatever. The sound produced by a therapeutic noise generator is described here as "waves on the shore but with no variation – it’s exactly the same from one moment to another", and that seems to me like white noise. |

calming/relaxing sounds Explanation: Those are the types of sounds (or noises) produced by a therapuetic noise machine. The aim is to relax the patient, or listener. Some people use these as a part of therapy, and others use them for home relaxation techniques or even for help falling asleep. Some examples of the types of noise produced are: waves on the beach (as previously mentioned), wind, birds chirping, and other "nature" sounds. As Ken and Egil noted, this is not white noise, which is a technical term. |
