Does this tunnel make a "crinkly" sound?

NO. There is an orange straight tunnel that does. But, that makes no difference in how much the cats like them. My six like both.

Oh yes, it does. My cat storm through the living room, through the tunnel, whack a ball that is in the track and then continue to chase each other. They have enjoyed it a lot since we got it.

At the most you will hear is the wheels running over the track.. It's a lot like a steady shhhh sound, and a little clack of the wheels as the train passes over the switch area.. but it's barely audible and unless your in the same room, you probably wouldn't even notice it.

no, you cannot hear it. I have it on a futon (which itself has a fabric cover - that's just how a futon is made) so that may be part of why. With or without sheet it makes no noise. I do notice the lower breath-ability though, so I may get a cotton cover to go on top for summer.

Depending on the adjustment of air it might sound a little. The more you open the adjusment the more it sounds.

No it does not make any noise when using. All fold up area's are very snug when fitted together. I love it being so compact. It easily fits in my oxygen carrier case when not needed.

There is a slight noise because the surface is ridged. It does not bother me.

It will make a slight gurgle noise, from time to time, but it isn't loud.I too, prefer utter silence, even when not asleep. I can't even hear this. It will be a slight louder when on high, but even then, you can't really notice.We have been very happy with this product, and have owned ours for 2 years now.

I haven't noticed any noise at all. We have had this box spring for about 7 months and it works great!

No it doesn't make any sound. I put a cuddly blanket as sheet over it otherwise it seems kinda uncomfortable with only a cotton sheet.

I'm with you Michele. There are two different sounds: the normal ratcheting the other commenters mention, and the "oh dear, I really think I just broke it" sound, which is accompanied by me having to push much harder than normal down on the lid. I've found this second sound occurs when the bag is somewhat full, and is a result of the closing mechanism being unable to twist the bag. I think it's a serious design flaw...we live in an apartment, and the people below us can hear the pail closing when it makes that second sound. Not great at 2am!

To answer your question, No it doesn't hum at all. You can't hear it, when it does actually have to put a bit of air in. It will let you know if you have a puncture by not filling it up all the way otherwise its quite as a mouse. This is my second never flat, not because the other one broke its because I moved from Oahu and left the old one in Hawaii. I have only had one puncture and it patched right up and the air mattress kept on keeping on.

There is a low hum sound, but usually it's only noisy when the water level is low. I don't find it bad at all.

it isnt noisy or squeaky. i've had it since April and it's the same now as it was then. i'm only walking on it though, so running might make a difference. as for the incline, i never go above level 2. never measured it.

I guess I don't understand what you mean by "screech." Mine just glide without any noise when scooting. Perhaps it's the type of wooden floor. Do you have wooden floors or laminate? Maybe that's the difference, I don't know.

None that I have heard, feel a slight hum touching it when it is warming up, thats it.
