It is not so much the volume of the sound as the frequency as well. Sound at the wrong frequency can be played as loud as you like and it will not break the glass. The sound needs to be the same frequency as the resonant frequency of the glass (tap the glass, that note is it's resonant frequency). Once the resonant frequency has been found, it does not take much volume at all, even humans can do it, albeit trained singers (see Mythbusters).
That depends how close you measure the glass smashing. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
sound is measured in decibles
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
Sound is measured in decibels. Decibels are units used to measure the intensity of sound. The highest decibel alarm clock available is 120 decibels, which can be compared to be as loud as the sound of a fire engine siren.
<p><p> Volume, as in sound volume, is measured in decibels.
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
Sound is measured in decibels
Loudness of sound is measured in decibels (dB).
Decibels
Sound is measured in decibels and is symbolized dB
•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons or a stereo can make up to 80 decibels. Volume is measured in decibels. So Frequency is measured in hertz
Sound is measured in decibels, which are commonly shortened to "dBs".

Sound is usually measured in Hertz.

Sound is measured in decibels. A decibel is 10logPower Out/Power In.
