Yes, some apartment buildings near Journal Square may have thin walls, but it depends on the building’s construction and age. Older buildings or those built with lightweight drywall often allow more sound to travel between units. Newer concrete or steel-structured apartments usually provide better sound insulation. Residents sometimes report hearing neighbors, hallway noise, or footsteps in certain buildings. Checking reviews, construction type, and visiting the property can help determine the building’s soundproofing quality.
