A Brookstone® exclusive that works like a dream!
Playing sounds based on Delta, Alpha, or Theta brainwaves, the Tranquil Moments® sleep sound machine coaxes your brain into ‘matching’ these frequencies–and entering healthier states of repose. Choose from 12 relaxing sounds developed by the Center of Neuroacoustic Research, including a summer chorus of crickets, authentic NASA recordings, and soothing white noise. Exclusive Sleep Enhancement Technology™ gradually slows playback speed over a 20-minute period to lull you to sleep. Just make a selection and lie back for a great night’s sleep!

Customizable…because no two sleepers are exactly alike.
Tactile buttons on top of the Tranquil Moments® sleep sound machine make it easy to navigate sound programs, adjust volume, set the timer, and activate our Sleep Enhancement Technology™. You can even adjust the unit's brightness–something no two sleepers seem to agree on–by feel. Here's how: With the unit on, press and hold the power button. The display brightness will automatically cycle through four levels of intensity. Release the power button to set the brightness at your chosen level.

I found this top-rated in Consumer Reports. It seemed right for me, so I immediately bought it on line. I'm a light sleeper, getting up at least once a night. Since using the product I sleep deeper and rarely get up, if I do, I can easily sleep again.

My only complaint is the lights behind the selections, they should have setting options that dim even more than they do, as they act as a night light which keeps me awake, the very thing I'm trying to avoid. I use deep-colored Post-it notes to cover them or I use a sleep mask. Once the light is out, the sound goes to work and soothes me to slumber. I never use the timer, just keep the sound on all night. I've shared my delight with others who have sleep problems, I'm certain some will purchase as I did.

I'm trying to devise a cover to shut out all light yet not cover any of the back where the sound comes through the speakers.

I like the choices and vary them with my mood, Ocean Surf, Summer Night or Rain are my three favorites. When I'm very stressed I use the Celestial and picture myself in space escaping my earthly concerns.

After only six weeks I feel my quality of sleep must be improving, no more wakeful times in the middle of the night and have less afternoon fatigue.

In the past I have tried prescriptions, over-the-counter and herbal sleep aids, consumed gallons of chamomille tea. This little device is so simple and so natural that it's hard to believe it can be this effective. If I were not happily retired I would market it for you at the Senior Center...I often hear of sleep complaints in my age group.

If this continues to work this well it will add many productive hours to my week, no longer needing mid-day naps. Time will tell, but so far, so good.....no, great!

I never write reviews for anything...However, I am now on my 4th...yes 4th Sound Machine from Brookstone..(over the course of 1 year...No joke).I have been using these for years...They had an old model that worked perfectly for at least 5 years...They make that model but it's for babies and it does not have A continuous play mode..found that out by purchasing it and having to return it...not part of the 4 others I returned...My problem is this...EVERY single one I purchased will shut off in the middle of the night...Starts off once a night...then twice a night and so on...My last one shut off and wouldn't go back on...I had it for 3 months tops...I am a VERY light sleeper and as soon as it shuts off I am woken up...Each one of these I had a minimum of 6 months when this started happening...I have had my newest one for 8 days and 2:00 am - there it went...I am so annoyed I am looking on line for other options...This machine is VERY expensive and does not work properly...I do NOT have the timer set at all....I put it on again tonight and after 10 minutes it went off...I am so frustrated with this thing....I will NOT purchase another one of these machines from Brook stone...When they work...They are fantastic...but since I have had 4 of them that have not worked properly I am done...There is an obvious problem with the computer or whatever inside the machine...

        After 2 attempts at this sound machine I will be returning it yet again. Very disappointed. My son needs it to sleep. It turns off when set to continuous. Then tonight 30 minutes after being on a loud horn like sound came from it frightening my son to the point of nightmares. Terrible.

              I really like the machine except for the bright light that I have to cover w a cloth at night. Unfortunately I seem to have destroyed the cable when I tried to plug it in in Denmark, using a regular plug converter. Is it possible to get a new cable, preferably one that will work in Denmark? Thanks!

                                This was a gift from my kids to drown out my husband's snoring at night. The first one broke in less than 2 months, the 2nd in less than 6 months and the 3rd and final just broke in the same amount of time. They just stop working...very dissapointing especially at a $129.00 price tag. Will never purchase again.

                                      I bought this machine in December of 2013 after my Tranquil Moments White Noise Machine for Baby broke after a year and a half. We use white noise to help my toddler sleep at night and nap time. In the first month, we noticed that the machine would often cut off after 10 or so minutes without warning. One day it completely froze and wouldn't come on at all. After about 5 minutes of tinkering with it, it started working again. Due to it's faultiness, I took it back to the store in March of 2014 and exchanged it for another one. I had the second for nine days when it stopped working completely. It wouldn't even work with battery power. I am extremely disappoined as these machines at Brookstone are some of the most expensive on the market. I am returning the second, and I will be going with a different machine. Please pay attention to the reviews. Many of the good reviews are written by people who have had the machine for a very short time. You cannot guage the machine's dependability based on these reviews. Many reviews state the machine is not dependable. Do noy buy it!
