Rumore bianco della LAVATRICE 💦Suono rilassante per dormire e calmare la mente

And what noise does it relax you the most? 😍 White noise is a particular type of noise characterized by the absence of periodicity over time and by constant amplitude over the entire frequency spectrum. It is called white by analogy with the fact that electromagnetic radiation of a similar spectrum within the visible light band would appear to the human eye as white light. In practice, however, white noise does not exist: it is a theoretical idealization, since no system is able to generate a uniform spectrum for all frequencies extended from zero to infinity, while in real cases of interest, white noise is at more related to a frequency range (finite or limited band white noise). A spectrum is thus often presented with characteristics similar to white noise, but with greater amplitude at low frequencies and less until it is zeroed at higher frequencies. #ASMR #RELAX #Whitenoise
