The Piattino Grand Piano Caster Cups are designed by German experts to reduce piano noise. They accomplished this by putting an acoustic break between the piano and the building. In Germany, the majority of people live in close proximity to others, and therefore need to reduce the noise impact of piano playing on neighbours. These caster cups are the most effective item on the market. That's because they cut down on the direct vibration transmission from the piano to the floor of the building. We are proud to say that Hanna Pianos is the only UK importer of Piattino Caster Cups.
Piattino Grand Piano Caster Cups' design allows to fit 1½” of acoustic insulating material between the legs of a piano and the floor. The cups lift the piano off the floor by only ½” due to their special cup shape design. This is important to maintain the correct height of the keys and the pedals from the floor.
In the same way as heat, sound travels in different ways. In buildings and rooms sound travels through the air, along ducts and under doors. Although sound in a room can carry through walls and floors the main culprit is the direct transmission of vibration energy. The entire piano resonates while someone is playing. The weight of the instrument on the floor makes for an excellent transmission of vibrations into the floor, which is essentially the ceiling of the rooms below. The amount of physical vibration transmitted by the piano through the case and the casters into the floor and the rooms below is substantial. That is why nearly all sound complaints stem from the downstairs neighbour, and not from upstairs.
Piattino Grand Piano Caster Cups reduce the direct vibrations between the piano and the floor. Note that these caster cups do not diminish the sound of the piano in the room itself.
We offer Piattino Caster Cups for Upright pianos 1 as well.
