to detect with sonic directional amplifiers.  Sounds like a great sci-fi
movie weapon - Hero hears the slowly building whining sound and knows
he's
in trouble...

Depends on the design and purpose of the weapon.
If it's for long-term use, like a mine, it will be in a vacuum on
frictionless bearings. No sound or vibrations.
If it's spinned up just prior to shooting, it may result in a hum.
Certainly
not very loud.
