Additionally, sealing any gaps or cracks in windows, doors, and walls can help prevent outside noise from entering the room. Using heavy, dense materials for furniture and decor can also help to reduce sound transmission within the room. Finally, minimizing the use of electronic devices and appliances that produce noise can contribute to a quieter environment. **
