This common phenomenon is known as resonance and occurs because the singer's voice displaces nearby air particles, which crash into the glass like invisible waves. And when the singer's voice is amplified, these waves get more powerful. With enough amplification, the glass can vibrate so strongly that it shatters.
Highly trained opera singers can sustain notes above 100 decibels. But no matter how loud the sound, if the pitch doesn't match the resonant frequency of the glass, the glass will reflect most of the energy and won't break.
If a person sings the same tone as that ringing note—a high C in legend but in reality the matching pitch could be any note—the sound of her voice will vibrate the air molecules around the glass at its resonant frequency, causing the glass to start vibrating as well.
Short Answer. It is possible to break a glass by singing, although it requires singing at precisely the pitch at which a particular glass resonates and with enough decibels to shatter the glass.
The note that a wine glass makes when you hit it is its resonant frequency - the frequency at which the glass vibrates most efficiently. If you can match this tone you can smash the glass. The note will be around one octave above middle C, depending on the size of the glass. The real trick is singing loudly enough.
While many an opera singer has tried to smash a wine glass with their pipes, US songstress Mariah Carey used hers to crack open a bottle of white Burgundy over the weekend.
Opera singers singing pop songs
Opera singers will sometimes sing pop songs, either by covering one with an operatic voice or by singing in a pop style.
To smash a glass, you'll need to blast it with upwards of 100 decibels of sound, which is roughly equivalent to a lawn mower.
In a 1985 interview, Fitzgerald remembered her Memorex audition at the Algonquin Hotel in New York: "They asked me to do the ending of 'How High the Moon. ' I just kept singing, 'High, high the moon,' doing the ending. And when the glass broke, they said, 'That's the one!'
Glass-shattering waves carry more energy. They're shorter and "choppier"; thus more of them pass through per second, at roughly 556 hertz [source: San Diego Opera]. To shatter glass, the note's frequency must be the same as that of the glass.
Does a glass have to be crystal to make noise? Glasses made out of glass do make noise, but it's clunkier in sound. A crystal glass sounds like a reverberated ringing, and it's more musical in nature.
Yes, they can. What is needed is a sound at one of the natural (resonant) frequencies of the object you want to break. You could find the frequency needed to shatter a wineglass, for example, by tapping it sharply with a spoon (not hard enough to break it!)
A glass has a natural resonance, a frequency at which the glass will vibrate easily. Therefore the glass needs to be moved by the sound wave at that frequency. If the force from the sound wave making the glass vibrate is big enough, the size of the vibration will become so large that the glass breaks.
These bubbles attach themselves to the sides of the bottle and collapse into one another. The collapse results in a superstrong jet that strikes the glass and produces a shock wave that breaks the bottle in that location. “You don't break the glass with your hand.
How High the Moon is written in the key of Fm. Open Key notation: 9m.
There is a particular frequency, called the resonant frequency, at which the sides of the glass will vibrate most easily. The resonant frequency of wine glasses is typically within the range of human hearing (20-20,000 Hz), and this is why you hear the resulting resonant vibration as a tone.
Tools such as a hammer, wrench, screwdriver or even a knife can help you break the glass if it is thin enough to make a hole in it.
Abstract. The new technique of using ultrasonic vibration to break hard rock is still in the experimental stage, but it has significant potential for improving the efficiency of hard rock crushing.
Sound is measured in units called decibels. Sounds at or below 70 A-weighted decibels (dBA), even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss.
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
The contralto voice is the lowest of the female voices and by far and away the rarest. The contralto range is roughly from the F below middle C to a high F one octave above middle C almost exactly matching that of the male countertenor.
Voice types in opera often differ to those in musical theatre, using much more vibrato – and are often much louder. This is because of the long history of the form, which was performed before microphones were created, so opera singers had to project over the orchestra without amplification.
The reason why resonance is a key factor for opera singers is that it allows their true voice to be heard with the utmost clarity, all without yelling. This can achieve varying effects, according to where a singer “places” their voice within their resonating chambers.
But it's Mariah Carey who takes the prize for the largest vocal range of all. She can reach a low F2 and hit an unbelievable G7, a note that dolphins would envy, and that only some dogs can hear.
