Marble dropping sounds in apartments can be caused by a variety of factors, including the movement of furniture, objects falling, or even the settling of the building. In some cases, it may be due to Plumbing issues, where water pipes expand and contract, creating noise. Additionally, sounds from neighboring units, such as footsteps or dropped items, can easily travel through walls and floors, causing the perception of marbles dropping. Insufficient soundproofing between units can exacerbate this effect.
