Does it emit sounds that penetrate through walls?

I haven't heard any sounds. It just blinks with the light when it's emitting the sound. As far as I know, ultrasound is impossible to hear. Can't tell anything about penetration. They claim it doesn't penetrate through a wall. I think, like any other sound, it depends on the wall sickness though...

It emits no sound that a human being can hear, but I can't think of any reason why the sounds that only the targeted animals can hear would stop at a wall. You should expect the sound to penetrate a wall, or not, the same as a sound you can her--depends on the wall.But, on the whole, I am not convinced that this thing does much of anything to control pests.

I don't believe so. The installation instructions direct that it be in line of sight of the area that it is protecting.

I'm not sure . . . I have it in a one room shed so it doesn't need to, and since it's at frequency that I can't hear, I can't say if it does go through those walls . . . haven't seen any rodent problems though, so I guess it does work

Per the manufacturer, no. It bounces up and down against the walls if placed on the floor and sideways if hung sideways. That said, I put the 2 of the product next to heat vents (1 per vent) on the floor with the idea of seeing whether it might work that way. As far as I can tell, it did. No sound of critters after that.

It depends on what you're actually expecting, but it makes several sounds that I would qualify as "buzzing." The built-in soundboard is basically as 90s cell phone. Jingle Bells, Fur Elise, generic ringers and some beeps. There are like 15-20 total. Be aware, though, this isn't strong enough to go through walls. Don't expect it to go through bricks to control your fire from upstairs. If you plan on using it like you'd use a TV remote, it may have enough range to work though!

No. This device amplifies all of the local sounds. It does not pick out certain sounds.

It will work only if the sound leaks from the walls / doors that you plan you cover.

Yes. MLV is used many times on walls/ceiling/floors to block sound transfer. Your results will vary depending on many factors including covering the entire surface, eliminating flanking paths (through the ceiling and floor) etc.

Don't think so. We just made sure we placed it in the center of our house out of site so we could hear it. Sometimes it sounds louder than other times. Haven't figured out why yet.

As far as I know it sends sound waves only in the room - I placed mine on the floor for as I feel the bugs will be zapped with the sound waves better.

No, the remote works through walls just fine. We use it on the first floor for a thermostat on the second floor, so it works through floors as well as walls.

Hi, I am sorry to say, but this unit cannot penetrate through walls. this will make you, or anyone who is in the apt very sick.

Yes it does but if you are trying to blast your music these speakers are not good

Absolutely not, Bluetooth uses radio frequency which will go through walls and such.

Yes. It has kind of a sideways funnel that points the sound into your ear canal.

I believe it does work thru walls and ceilings. We are very happy with the results....

No, It's just a trigger. It needs to be fed into a sound module to generate a signal your ears can recognize. Sorry.

it will definitely muffle and reduce the transmission of sound, but not completely. also it's not really meant for that purpose, it's primarily meant to go inside the walls

Yes. When they call it comes through the speakers. At least in my car it did.

Absolutely yes. It works great even throught several walls when I am in my house.
