I am wondering if it is possible to build a one-cubic-meter soundproof space or other similar size of soundproof space.
Why would I need this? I am planning soundproof my house, although I am new to soundproof. So, if I can build a group of test spaces with different solutions, I can get a comparison result to decide which one is suitable to. the smaller the size of test space, the less cost I spend.
So, what is the minimal size of a soundproof space I could build?
Note: both inside and outside of the test space is full of the normal air as the daily environment we live in.

A small-scale model won't produce accurate results. You will have different standing waves, resonances, and modes in small cube than an odd-shaped real-life room. Different cube-lining materials will provide a baseline relative comparison, but the results shouldn't be extrapolated to a real-life situation without careful acoustical modeling.
