Fabulous machine and would buy it again & recommend it to anyone.
I'm one of those people who is very sensitive to unwanted noise. It's a curse I've had since a child. I have a sound machine of some kind in almost every room. I used to use fans but those would get kind of cool in the winter! I even went to a sporting goods store in desperation to block out loud barking and bass music sounds and tried earmuffs for gun ranges! But the guy there told me you couldn't block deep sounds so low in the spectrum because you weren't hearing them with your ears, but with your body. I bought this sound machine to replace an older model of the same kind for when I travel, especially internationally, because it can operate on batteries. My other unit has lasted years and is still running, but the battery section no longer works. This new unit sounds as good as my old one. I like white noise the best because it has the most even, non-invasive tone. I don't like that it now has a knob you have to turn on and off as opposed to a push button, but I can live with it. It would also be great if it had a headphone jack but I have my iPad white noise for that. As for these sound machines blocking dogs barking or music or loud talking and my latest nemesis, the motorcycle across the street, I haven't found anything that could do that. But these lessen the irritation of softer noises or even too much silence when you are trying to work and want to increase concentration
