This application containing the best collection of glass breaking sounds for android devices. Sounds have been selected very carefully to be a good and fun user experience, we hope you will enjoy using the app and listening to glass breaking sounds. 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.
