How Can I Hear Through Walls?
Chances are if you've ever seen any James Bond movie, you've seen all sorts of types of spy equipment, including little devices that lets the secret agents hear through walls, so they know what's going on on the other side. Believe it or not, that technology actually exists!
Of course there's always the low-tech version of taking a glass and putting it up to a wall, but all you really get with that is muffled sounds...you can't actually hear anything that well, unless you're trying to listen through a sheet of paper.
That's where the Surface Microphone comes in handy! This is a powerful listening device that allows you to hear through walls, or any other solid surface. All you have to do is press the device up to a wall, and insert the earbuds in your ears, and adjust the sensitivity knob. By adjusting the amplification power, you can easily hear through solid surfaces like walls, doors, or anything else that you might want to listen to.
How is this even possible?
The Surface Microphone works by amplifying faint sound vibrations, and converts these to audible sounds that you can hear plain as day. Not only will the Surface Microphone allow you to hear through walls, but you can even plug in a voice recorder device and record what you hear. Perfect for law enforcement and private investigators who need to gather evidence. It can even be used by spouses and parents who need to find out if a spouse is secretly talking to someone in the other room, or to find out if your children are talking to someone they aren't supposed to be.
