Misquito Ring Tone
Have you heard about the cell phone ringtone that junior high and high school kids are using to keep teachers from discovering that they are using their cell phones in school? The pitch of this ringtone, called the "mosquito tone," is too high for people over 25 to hear. So the kids can still send and receive text messages during class without the teacher knowing. I’m going to have the guys in the soundbooth to play it right now. Did you hear that? Amazing isn’t it?
The mosquito tone was first developed in Great Britain to irritate teenagers who were loitering around convenience stores and keeping customers away by their loud and obnoxious behavior…
Some kid simply figured out how to use that sound as his cell phone's ringtone and—voilà—kids are downloading it by the millions.
How does the mosquito tone go undetected by adults older than 25?
Inside our ears we have tiny microscopic hairs that move with the impulses of incoming sound waves, and those hair movements send electrical signals to our brain. As we age, those hairs get worn down, actually damaged, so our hearing becomes less sensitive. We first lose the ability to detect the sounds of high frequencies. People over 25 can't hear sounds above 16 kilohertz. (The highest note on a piano is 4 Khz; the mosquito tone is 17 Khz.)
Here’s the point: Believers who have their minds set on Christ and who are pursuing maturity in Christ grow “spiritual ear hair” so to speak. They can sense the voice of God as He speaks to them and I want you to know that this ability is crucial to going from good to great as a believer.
