What are the best techniques for using soundproof glue to effectively reduce noise in a room?

To effectively reduce noise in a room using soundproof glue, the best techniques include applying a thick layer of the glue to all surfaces where sound can penetrate, ensuring a tight seal between materials, and allowing sufficient drying time for the glue to fully bond. Additionally, using multiple layers of soundproof glue and combining it with other soundproofing materials can further enhance noise reduction.
