Hello,
I am having this small confusion about sonic boom. Let's talk about aircrafts of the future -say having electric, noiseless engines (suppose). Essentially, these aircrafts practically generate no noise while flying. Now, if these aircrafts can travel faster than sound, will there still be sonic boom - in terms of loud noise and shattered window-glass?

Welcome to the PF. :smile:

Yes, it will still generate a sonic boom, since that is caused by the air being displaced by the aircraft as it flies, not engine noise.
