Your post brings to mind an experience I had. The elderly customer met me at the door and on the way to the piano she said " I want you to tell me whats wrong with my piano. These notes don't sound, playing keys in octave 6. I did not understand her question asm I heard nothing out out the ordinary for a small spinet that was 65 cents flat. A little discussion followed during which her daughter entered the room and said, "Mother, those notes are sounding. You can't hear them." This satisfied the mother and she said that she could feel them hitting but could not hear them. The most interesting part of this episode came later. She agreed to paying for the pitch raise and tuning to bring the piano to A440 and when the job was finished, it was apparent that she could now hear notes a full octave higher than before even though the pitch was now higher. The only explaination I have for this is that the additional tension on the soundboard gave increased amplitude. Any other explanation for this would be welcomed and appreciated.
