When OFF, does it block out noise from outside?

It cuts down on noise but doesn't completely block it out. Certainly less noise then if the window was open without the a/c in place.

It does help block out a modest amount of noise, but it is not a solution for large noise issues. I hope this helps.

No, it just makes white noise or various soothing sounds. That would help you ignore the noise from your neighbors!

Yes, but it is very loud! We've only use it twice but definitely turned it off during quiet hours.

The headphones have noise cancellation, but all that does is block out outside/ambient sound. So while they prevent outside noise from getting in, they don't stop noise from getting out. From my experience though, even when turned up loudly, it was not able to be heard by others.

It depends on how loud you listen to the music in your ears, if it's loud, it should drown out exterior noise pretty well

no! do any block out ALL the noise of a gun? They reduce the noise to a comfortable level. For the money, they are excellent!

No they don't block out noise. They work for me because I want to be aware of sound around me but I can still enjoy my music at the same time. I hope this helps you.

No. It had minimal noise reduction. Try a additional or larger gauge ground wires. Good Luck

I would say about 90 percent of the outside noise is cancelled by the headphones but there is no difference when you turn on the noise canceling feature.

It helps eliminate noises, but does not block all noises out. Plus it only works for the peson who has it in the room, so if you are trying to block out your noise so the neighbors dont complain or hear, then you need to buy some ear phones and be more respectful.

The white noise setting pretty much does, although some of the other settings may not, as the sound is more intermittent. However, I'm not sure if it would block neighbors from hearing you, although probably, but only if you place it near the wall you share with them. It will block you from hearing them, though.

Yes. It's noisy when air moves through with the unit off, when it's windy outside. It's probably best to use an outside vent cover that has a good built in flap.

It blocks out sound quite well. I have it nailed to my window and I hardly hear anything save the soft wailing of the siren of a fire engine or ambulance.

Yes. The noise reduction is very good. You can drown out the outside without having to shatter your eardrums.

No. At least for me, it was not cancelling noise that well. I could still hear external sounds.

NO! it does not. Don't spend your money on this if that's what you want. I use this daily and it does not cancel any noise whatsoever. I can still hear noises outside on all types of music(Rock,Jazz,Classical,etc).
