Fill any gaps or cracks by using an acoustic caulk. Acoustic Caulk is specifically designed to soundproof gaps and cracks in walls and ceilings.

You can easily find the right acoustic caulk for your damaged wall at any local home improvement store or if you’re exploring a particular brand, you can find it in an online store.
