we live in a large condominium in so . ca . and the lay back atmoshpere of the daytime can soon become a beehive of activity at night . I like to sleep with we window open to enjoy we cool ocean breeze at night . needless to say , along with the cool breeze come the cool pool party and patio gala . my husband buy I this sound soother to help block out the late evening noise on the weekend . we love it and now sleep with it on every night . have work through most of the sound , they be very authentic and natural . one thing I would have like to have have would be a light control area on the top of the unit . turn the volume up and down , change the sound pattern , or even just set the alarm require turn on a light in the room to do . also have a time projection on the wall or ceiling would be terrific . every bedroom across America should have this machine ... baby too !
