Single Speed is HIGH SPEED
I'd like to thank a previous reviewer who confirmed, before I ordered, that this SS single speed gives you the high speed (Loudest) setting.<br /><br />Yes: this SS unit sounds just like the LOUDEST setting on the Dual Speed unit.<br /><br />I had a DS unit on High right next to this SS unit and they sound the same. Very happy. I'll probably be ordering a third one for the other end of the house. I have a DS for my bedroom (I like the low setting if I have a migraine) but I use this SS in a Computer/TV room with a window overlooking my neighbor's barking dogs.<br /><br />If you have a noisy neighborhood, or just want white-noise to fall asleep by I highly recommend this product. During the first week it actually kept me awake-but since then I find it indispensable. I use them during the day to drown out barking dogs and street noise while I read or watch TV.<br /><br />These devices do very well against: dogs, kids playing, cars driving by and other noises. They do NOT drown out lawnmowers, snowblowers or booming car stereos as well. I found that out when my neighbor's lawn/snow removal service started showing up after midnight on occasion. I will say that while I can still here those things while reading--if I was asleep I don't think those things would wake me up. I LOVE THIS THING!!!!!!!!
