Dense materials carry the sound! I lived in a high rise with concrete subfloors and you would not believe how sound carried! You wouldn’t hear talking or TV but any tapping, banging, or similar carried like crazy! When we had a toddler across the hall, his dropping toys on their wood floors sounded like golf balls bouncing on my head.
