Image via Wikipedia Try closing you eyes and walking through your house or around you office. It's hard but it's good for your senses and kind of fun (as long as no one gets hurt).

Now switch from trying to use your eyes, and turn your ear sensitivity to 11. Listen carefully to your footsteps or the sound of your clothes swishing against each other and you can actually start to hear sound patterns as this noise bounces off nearby objects and start to recognize telephone poles, buildings, and even doors from their sound patterns. These sound patterns are just simple changes in the reverberant qualities around you that are inherent to the immediate environment.

It's the same as when you drive by fence posts or telephone poles in your car; you can hear them whoosh by, but they're really not making any sound, it's just the sound of the car that you hear reflecting off of them.

This is a great way to increase your awareness of the things around you as well as your own sensory perception. And yes, it's kind of like a primitive form of radar, just like what bats use. But it's only primitive because we never learned to use it!
