Gentle pressure, not a jab. You just want to see if the string moves (i.e., pitch changes), which is the purpose of a hard blow. However, the shank can deflect more than a test blow will; hence the effectiveness. Not that you need to be moving the string very far, but it’s more effective than smacking the heck out of the string without the damaging and/or painful effects of a hard blow. In other words, you’ll get more deflection with the shank than a hard blow.<o:p></o:p> <o:p> </o:p> Funny on me. After I posted this, I started thinking, hmmm…seems like this has come up on the list before. So I did a search, and found that yours truly mentioned this back in November 1999. Aaggh! How embarrasking! I remember the class now…my first convention, Steinway all-day, John Patton session. I’m only 35, so I can’t claim this as a senior moment.

The idea is that a hard test blow will show any string movement (from deflection by the hammer). A deflection by a hammer shank will also do this, but at a greater level than the severest test blow ever could. I used this yesterday on the four pianos I tuned (2 verts & 2 grands), and it worked very well, although it’s slow at first b/c it’s a new skill. I gave one string ten whacks as hard as I could, and nothing moved in the slightest. I also did a few hard blows in various sections to ensure that it works everywhere. I’m very glad to know of this as my playing/test blow elbow has been sore lately.<o:p></o:p> <o:p> </o:p> The only downside I can see is that it might take a bit longer at first. (Leonard tunes in 45min to 1 hour, so it hasn’t slowed him down.) The positives are that we won’t have hearing loss from hard test blows, and body damage is also greatly reduced. I’ll gladly trade test blows for a few more years of hearing and less pain.<o:p></o:p> <o:p> </o:p> John Formsma<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <DIV> <DIV class=MsoNormal style="TEXT-ALIGN: center" align=center> <HR tabIndex=-1 align=center width="100%" SIZE=2> </DIV> From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On Behalf Of Geoff Sykes Sent: Thursday, June 08, 2006 2:00 AM To: Pianotech@Ptg. Org Subject: More on hearing protection<o:p></o:p></DIV> <o:p> </o:p> <DIV> With the "Noise-Induced Hearing Loss, Part 2" article in the Q&A section of The Journal, I'd like to hear from some fellow tech's who have tried the Zem earplugs, by Sensgard. They're ugly, but the technology is such a different approach than just a simple "plug" that perhaps they could be very useful. I have been using 32db foam Hearos, but I find that while the foam is comfortable I get a lot of attenuation variation from one set to the next, and they're not that flat in response. I also have a pair of Etymotic High Fidelity Earplugs, (identical to the Hearos High Fidelity Ear Filters), which work great. My only complaints are that they're not that long term comfortable ! and tha t since the frequency response is much flatter, the attenuation, (rated at 20db), is perhaps a little too much. Zem claims 32db reduction. <o:p></o:p></DIV> <DIV>  <o:p></o:p></DIV> <DIV> -- Geoff Sykes<o:p></o:p></DIV> <DIV> -- Assoc. <U1:PLACE u2:st="on"><U1:CITY u2:st="on"><st1:City w:st="on"><st1:place w:st="on">Los Angeles</U1:CITY></U1:PLACE></st1:place></st1:City><o:p></o:p></DIV></BLOCKQUOTE></BLOCKQUOTE></DIV></BLOCKQUOTE></BODY></HTML>
