(Pebble) Rock and Roll
As a natural source of White Noise, waves crashing on the beach help blocking out distracting noises or even your tinnitus. Their relaxing sounds will gently lull you to sleep.
myNoise already offers many realistic soundscapes build around the ocean theme: Irish Coast, Intertidal or Subaquatic Dreams to cite a few. This one is different, not only because of the myriad pebbles shaping its sound, but also because this one is calibrated. Calibrated noises on myNoise can be precisely shaped to any spectral color (brown, pink, white noises, and so on). They can even compensate for your hearing loss (see below).
