To do it with sound you need a sound that is a resonant frequencies of the glass you want to break. A sound that is the right frequency with enough volume will put energy into the glass and break it. Glass is one of the easiest materials to break using sound although any object can be broken using sound.

A high enough air presure difference on glass surface will cause it to break. This is why they say to open Windows when there is a tornado.

Rapid temperature change (hot or cold) is the most common ways that glass is broken without any
