As seen on sci-fi and action movies, heroes and villains fighting on air while glass windows and whole buildings are smashing down. Well, this scenario is too far from reality to happened. But, seeing movies or TV programs having female singers screaming or singing out so loud that can really shatter window glasses of nearby houses is also a common thing. However, the question is, does screaming or singing out loud on a particular music at high pitch can really shatter window glasses?
Why screaming or singing at a high pitch can shatter window glasses?
Even screams or high pitch tones are music to our ears. That’s the reason why we appreciate music. And, below are explanations why window glasses can shattered due to high pitch sounds or voices.
SOUND WAVES
Sound is one form of energy similar with electricity. The usual pathway of it is through waves via various substances. In case, specific sound waves connect with a particular object, the particles inside the object become excited thus causing them to vibrate opposed to each other.
FREQUENCY RESONANCE
Frequency is the count of waves that passed on a single point on a 1 second duration.
Hertz is the unit measurement of frequency. Each substances has a specific natural frequency in which every participating particles vibrate. The frequency should be lowered down into the limit of a resonant frequency of a certain object to make the wave create vibrations. In some cases, loud music from the speakers can cause shaking and peeling off of the plasters inside your room. This simply means that the sound waves produced by the speakers lies between the resonant frequency limit of the plaster.
THE STATE OF GLASS SHATTERING
Here are some factors for a human voice or a high pitch music to break a window glass.
- The wave frequency should be at least 550 Hertz. Meaning, an individual should achieve that frequency to break a window glass.
- The intensity of the sound should be strongly loud in order to transmit enough energy to vibrate the particles of the glass. A human voice is not enough to produce that intensity. An artificial equipment is needed in order to break the glass.
- Minor glass defects is a contributing factor to shatter it easily. Those defects may be a potential weak spots to make it break. That’s why it is important to check the window glasses quality at the very beginning to the service provider.
