CAN YOU HEAR ME NOW?
A humorous, but very effective telephone system commercial has been shown numerous times on television. Many of you have probably seen it. The commercial illustrates and promotes the extensive range of their phone product by showing a man who travels to various remote out-of-the-way locations. Then, while at each location, he speaks into his cell phone always asking the same question.
"Can you hear me now?"
The signal being sent from that cell phone is only one of thousands of invisible sound waves that constantly surround us from phones, radios, televisions, and countless other electronic gadgets. We are not aware of the signals because we are not tuned-in to receive them. Only after we become properly connected to the frequency can we clearly hear, and then listen to the message being sent.
