Can a singer break glass with his voice?

in #glass5 years ago

Before you fill your lungs with air and try for yourself, you should know that most likely your voice capabilities are not sufficient to open the work of neighborhood china shop.

On the other hand, the laws of physics actually dictate that each person - when he sounded the correct frequency and with appropriate reinforcement - can be crushed glass.

All items have what in physics is called the natural frequency or frequency with which the object vibrates. If you press a fork to wineglass, ringing sound it produces is its natural frequency.

Human voice, producing the same natural frequency, also would make the glass vibrate. This phenomenon is called resonance occurs because the voice of the singer displaces nearby air particles that slam into the glass like invisible waves. And when the voice passes through the amplifier these waves become even stronger. With enough effort glass can vibrate so strongly that to burst.

Of course, for this to happen it is necessary and conditions are favorable - glass walls are thin, and even better is already cracked.
