What can I buy to soundproof my bedroom? I want to stop sound from leaving the room so that I do not disturb my neighbours while being loud and livestreaming.

Search for "anechoic chamber" and "anechoic chamber diy".

What surfaces (floor, ceiling, wall(s) ) are your trying to soundproof. Do these changes need to be removed without damage?
Simplest thing is a heavy area rug. That isolates the floor.
You could hang quilts on walls. Ceilings are the most difficult. You would have to glue sound insulation to the ceiling.
Also remember the window. Heavy curtains to limit sound transmission to the window.
