I have a sound machine called Sound Oasis.
It comes with a card that plays 5 sounds, ocean, rain, nature walk, white noise and one other I can't remember right now.
The nice thing is you can set to play however long you like.
I find the ocean to be very peaceful and soothing.
This machine uses a card, and there are more cards available to buy for other sounds.
Just a thought.
