Dampener question

[sureshs]

This issue of Tennis mag quotes an expert as saying dampeners cannot damp the large vibrations of the racquet but just reduce the sound (the irritating ping).

It is probably true, but the reason given was that they increase the mass of the racquet slightly and hence change the frequency of vibration.

Isn't it more correct to say that they reduce the vibration of the strings by clamping them and this reduces the sound?

Otherwise adding lead should also change the sound. And I am not sure the weight of a light dampener (2 g) is comparable to the weight of the strings (15 g), if weight was supposed to be the reason.

Sound is generated due to vibrations....
So I think vibration dampeners DO reduce vibrations....

Yes, of the strings.

Which was attributed in a confusing way to extra mass in the article. Confusing because it was not clear whether they were talking about the frame or the strings, and also because they emphasized mass, not clamping.

I remember reading that a heavier frame vibrates less....

Then, if you add lead, the racquet's vibrations should change.
The sound should chagne then or the vibrations would be dampened....

True, but not what I was trying to focus on.

Yes I know. I am just saying I am not sure whether added mass is the reason for less sound.

Mmmm....
Interesting....
I'll investigate, when I find out, I'll let you know....
