The SleepMate and Sound Screen are offered in both Single speed (model 580) and Dual speed (model 980). The tone and volume of the sound are controlled by simply rotating the "cap" (top) and "collar" (side) of the housing. I recommend the Dual speed because it offers even more control of the volume.
Heres how it works: The cap and collar have small openings in them. By rotating the cap and/or collar, you allow more or less sound to exit these openings which affects the units tone and volume. The 980 has high and low settings (dual speeds) offering a greater range of tone and volume than the single speed setting of the 580. At the bottom rim of the unit, there are tiny openings that allow air to enter.
Please note that the openings at the bottom rim must never be covered or the unit will overheat, malfunction and ultimately, fail.
SLEEPMATE or SOUND SCREEN
Dont be confused as to which one of these to buy. They are virtually identical except for their names. The Marpac Corporation realized the name, SleepMate would not be well received by their secondary market: companies who are essentially looking to increase productivity in the office.
To Marpacs thinking, no company wants their employees to use a product, while at work, with the word, sleep in it. Enter the name, Sound Screen.
LESS IS MORE
Unlike most other sound conditioners whose sounds are processed, simulated, replicated, digitally enhanced, and then looped, the SleepMate/Sound Screen uses the simple, natural sound of real whooshing air. The 980 and 580 produce white noise mechanically (like a fan) - all other models produce white noise digitally.
To name just a few, the SleepMate/Sound Screen successfully masks out
Television and stereo
Tinnitus (ringing, buzzing in the ears)
I own two SleepMate 980s. One is "permanently" plugged in on my nightstand and the other is for staying overnight elsewhere. It is a lifesaver! Now, I need not worry about unwanted noises awakening me. The gentle, whooshing sound of air melts into the night blocking all unwanted noises.
Unless my SleepMate is on, sounds like barking dogs, street noises, lawnmowers, slamming doors, and other sounds that go bump in the night and early morning can and probably would awaken me.
The closer you place the SleepMate/Sound Screen to your ears, the louder the white noise is. On rare occasions, while travelling, the external noises were so loud and so frequent that I had to place the unit literally on my pillow. Needless to say, I slept peacefully.
The SleepMate/Sound Screen has proven to be a durable and effective design. Tests have shown units that are used on average 8 hours per night, last at least 15 years or more.
Marpac Corporation was founded in 1962 as Buck Manufacturing Company in Elkhart, Indiana. The company was formed to produce the original "Sound-O- Sleep" sound conditioner which was invented by Jim Buckwalter for his personal use.
The "Sound-O-Sleep" quickly became popular among his friends and acquaintances, and was to become the first successful sound conditioner for consumer use in the world.
In 1968, operations were moved to the present location in Wilmington, North Carolina. In 1997, Marpac became an employee owned company.
