I play this at night time for my 9 month old daughter. The sounds are clear and crisp and theres many different to pick from. I love the ocean sound, brook, and thunder the most. It has a timer so if you only want it on for 30, 60 or 90 minutes, or to play infinitely you can choose so. I recommend this to anyone who loves having white noise playing in the background . It really helps with babies for more peaceful sleep too.
