When I was a bachelor and still had disposable cash I wanted to build a stereo so powerful that if you put in a blank tape and turned up the sound you would need to shout over the silence.
There is a form of loud silence in the realm of sound cancelling. Like the headphones that block out background noise by playing the inverse of the noise into the headphones to cancel it out. In industry they use the same technology to mask the noise from equipment to help maintain a suitable work environment. It is an example of very loud noise for producing silence.
