Tips for Insulating Piano Sound

Insulating the sound of a piano
A (grand) piano often turns out to be an annoying source of noise for neighbours. The source of the noise consists of two elements: contact noise (the transmission of resonances/vibrations) and airborne noise (the sounds of the instrument). This tips page explains the solutions to both problems.

The solutions
There are two solutions to reduce piano noise to your neighbours. The first and best solution, but also the most radical one, is to apply the box-in-box principle. This means that the wall, ceiling and floor are not directly exposed to the airborne noise. This implies that a small renovation is required, equipping the walls, ceiling and floor with insulating products such as Merfoflex (floating wall and ceiling) and Akoestifloor (floating floor). You can also apply an easier solution a two-step plan that does not require any tools and no renovation! On this page you will find out how.

The two-step plan
If you don't intent to place partition walls in the living room, this step-by-step plan is an excellent intermediate solution. Below you will find an explanation of the implementation of this plan in order to reduce the loudest noise, without installing an additional wall or other constructions. A nice side-effect of this plan is that the piano often sounds richer as well.

Step 1
Contact noise, vibration insulation

To isolate contact noise, i.e. vibrations, choose a product that fits best under your (grand) piano. Pay attention to the dimensions of the piano legs or wheels and the selected product. The following products can be used to reduce contact noise:

  • Pianodempers: Black lacquered steel dampers for applications with wheels or square legs up to 78 x 78 mm. One set consists of four dampers.
  • Regupol: Rubber granulate strip for pianos with long and narrow legs without wheels that don't fit piano dampers. Ideally, use two strips on top of each other under each leg. You need four pieces for one piano.

Step 2
Airborne noise, sound absorption

A problem that often occurs is that the instrument sounds slightly too bright, which also causes more nuisance to the neighbours. This is especially true for rooms that don't have optimal acoustics to begin with. In this case, the sound of the piano travels through the wall into the room, thus being amplified. For this second step, absorbing airborne noise, it is best to use Akotherm GG. These absorbent plates are placed behind the piano. The plates are stable enough to stand next to each other, without the need for mounting tools. Slide the piano gently against the Akotherm GG plates and you're done! This step ensures that the piano sound is somewhat muffled and that the partition wall with the neighbours is not directly exposed to the sound.

You can individually decide how many plates you apply. The thicker the layer of Akotherm GG, the better the result, but the further the piano sound enters the rest of the room.

Customer review about the above tips
We received the following message from a satisfied customer. The situation of this customer was as follows: He owned a piano of 124 cm high and 148 cm wide with a weight of 255 kg. The neighbours experienced nuisance, especially from the low tones. The house in question was built in the late 90s.


I have positive news: I played forttefortissimo (fff) and the neighbour thought it sounded softer than it was in actuality. Not completely gone, but considerably less. The dampers work well. Some feedback, you can no longer move the piano when it stands on top of the dampers. So, I can't move the piano into the corner, because I would need to lift it (or I would need a pallet truck ...). Furthermore, the absorption plates function well; it is a bit more comfortable in the room in terms of sound level, without me having compromised in terms of sound formation and tone formation.

Kind regards,
