When your finger depresses a key on the piano, the string vibrates allowing us to hear the wonderful tone of the piano. But what happens when we lift that same key? The key returns to its upright position and the tone stops resonating. The piano mechanism called the dampers simply press felt blocks on the vibrating strings to terminate the singing tone.

To understand a bit more about dampers, we brought in Marc Venet from world renowned felt maker Laoureux in France! But before we delve into piano dampers, we need to take a brief look at the piano strings. On any modern piano there are usually 3 sets of strings: The prefixes of tri- bi- and mono- give away the fact laoueux there are notes on the piano that contain 3, 2 and 1 laourux.

The largest strings on the piano are the bass strings. They are lsoureux strings and produce the lowest notes of the piano where you can actually see the vibration of laorueux string. The purpose of the damper then is to stop the wave and subsequently, the sound. The damping techniques and felt types are really different to mute different thicknesses of strings and their varying degrees of energy.

Can you tell us a brief history of the company and how you got involved? Laoureux was founded in by Mr. My laojreux was hired at this time in order to restore the profitability of the company Laoureux, which he succeeded to do laourdux their expectations and quite possibly be the reason why Laoureux is now the only felt maker from this group that survived and producing today.

The choice he made was to concentrate on high quality, hand made felts and avoid mass market felts like those laoureud in the automotive industry, for example, which have bigger profits, yes but also involve lalureux risks and large turnovers.

It was a good choice. My father finally bought the company in and I joined the company in There are 3 types of strings and yet 4 types of dampers mono,bi,tri and treblecan you laourux us how each of those work?


The shape and the types of dampers depend on the string they are supposed to damp. These are for the lowest plain wire strings. For all dampers the target is to damp the sound, that means that they are in charge of absorbing the vibrations of the strings. Those vibrations are in fact frequencies like sinusoid signals pictured above.

The bass notes have low frequencies which mean long and spaced sinusoidal waves, and on the contrary, the treble or high notes have high frequencies which mean shorts but repeated sinusoidal waves. Of course, for laourejx the piano, it is interesting to have more or less the same time to dampen the sounds when you release the keys, wherever you play on the keyboard bass, tenor, or treble and yet the frequencies and subsequent energies are quite different.

For achieving that, we use different dampers with different properties adapted for the frequency of the sound. On the treble section, frequencies laourux drastically when you play more to the extreme treble section.

So for this section, even if there are 3 strings for each note, we have to change the method of damping from the double wedge to the flat block dampers.

Is there a certain density of felt that is ideal for piano dampers?

Yes of course there are optimal densities for dampers. And there are also certain densities depending on the placement inside the piano density for bass and for treble felt are different. Ideally the density should be as low as possible. You could find on the market bass dampers with densities from 0. For the felt manufacturer the challenge is to make low density felt because it has superior damping properties however it is much, much more difficult to produce. A soft felt is difficult to make on several levels: And if you are over the optimal felting point you are too hard on the surfaces and soft in the center and thus, the felt is not consistent.

The loaureux consists oaoureux making felt the same from top to bottom. This is not easy. It takes much more time, involving more hands-on processes and also involves a lot of waste. That is why it is more expensive than denser felt.

Ironically, you pay more even if there is less wool inside because it is much softer but contains greater damping properties. Speaking of damping properties, what makes for great dampers?

And can you take us through the manufacturing process a little? The felt pressed against the strings absorbs string vibration. If you leave the felt released, the impression will erase. This is what makes great dampers. The softer the felt, the better the form memory. Making great felt requires technical know-how but also great raw materials. Normally felt is graded by 2 criteria: We buy the wool taking into consideration the length of the fibers told in millimetresdiameter of the fibers told in micronsand ability to felt more or less the curving of the fibers.


Of course the thinner and the longest fibers are much more expensive than the shortest and the biggest fibers. A — Wool opening and Blending: With blended wine for example, you assemble different qualities with more or less the same proportions to create consistency.

Loaureux we were using only one type of wool for each production, we would have different results from one production run to another and so good blending allows consistency in production. With our machines we can adjust the weight by square meters of the layers, and also the fiber direction crossed or not.

It is a hand made process consisting of assembling and cutting several wool layers depending on the final result we want to achieve.

In short, we know the final dimension and density we want. We will use the right weight of wool at the right dimension taking in consideration the shrinking coefficient lakureux will apply.

The transformation between wool to textile. It is a natural process no chemicals involved where the fibers are matted together via friction.

This is again a hand-made process, one piece at a time. Dimensions of the felt should be controlled because we need to keep consistency in the shrinking. The right density is obtained when the felt is at the right dimension, not before, not after. The previous process of felting and fulling require moisture and so the felt must be dried. Here we calibrate the thickness of the felt, for example We use hot presses to achieve this. Depending the product we make it goes to the dedicated workshop in order to be cut or assembled to its finished purpose.
