Hello Timur,

I see that you are a University Technician, but haven't noticed whether
anyone's responded to your question yet.

The problem you describe is a little complicated, so let me suggest this for
starters:

Go to www.RennerUSA.com click on the "technician's pages" and select
"Voicing the Renner Hammer"

At very least, this is a good orderly approach for dealing with the likely
causes of the noise you describe: hammer condition, string bearings and
terminations, and hammer-to-string mating.

It might be helpful to follow this process step-by-step for all the notes in
one octave only, to see if it helps. (you mention agraffes, so perhaps the
tenor section)

It will also be helpful for you to determine whether the noise is from
hammer/string condition, or from the soundboard, loose bridge-pins, plate,
cabinet, etc.

(pluck the string and listen for noise)

Finally, there is an excellent article on agraffes in this month's PTJournal
www.PTG.org

I've had several situations where 'forte' noise appeared "after" string
lifting/leveling. It was from the agraffes and was only corrected by
vigorous string-lifting on the "other" (non-speaking) side of the agraffe.
This noise is more "rattle" than "buzz" however, so it may not be the
problem you describe.

please write again with any questions,

sincerely,
Mark Cramer,
Brandon University

Good day! I am Timur Rizayev piano technician of Mahidol University,
Thailand. Also, I maintain and tune the pianos in one studio of
Steinway Artist. There I have sime problems with voicing. It is about
20-years D-Steinway, Hamburg. Over 6 months ago I've installed new
Steinway hammers with hammershanks, shaped and voiced. Resently I
tuned and made correct of voicing. But his claim: he want to listen
rich, harmonic tone, but don't like the more bright sounding sometimes
with buzz tones in the forte playing. If I make more soft hammer felts
by needling, in result more noise part in the soundind. Yes, it is
affect of the used original strings, used original agrafs, degreased
crown of the soundboard. Maybe somebody can suggest me how save the
hamonic tones in the sounding and avoid the buzz sounds in the forte
playing.
Thank you in advance,
 With best hot tropical regards,
