So i live in a one bedroom apartment with my girlfriend. The bedroom is separated by a short hallway to the living room and the living room doesnt have a door. Just walk in/out. My girlfriend is starting to get annoyed at my several hours of guitar practice. And i normally play via headphones so shes getting bothered by the actual acoustic sound of the electric guitar when i play lol. Is there anything i can do to lessen the sound. Some sort of sheet i can hang in the living room entrance?
