The Marpac 980 Sound Screen & SleepMate Sound Conditioner was a birthday gift for my wife. She used one at our son's home and loved it. Since the first day of using it, she sleeps well and I sleep better. She has not poked me once to say "stop snoring". She now says that I do not snore. The sound conditioner is a "white noise" that can be adjusted for volume and some limited range of frequencies. The noise is constant and masks any intermittent sounds. I was a skeptic but this product works better than I could have hoped. I also have tinnitus (ringing in the ears) and this helps with that condition as well, at least while I am in bed. The product is great. I whole heartedly recommend it.
