This data was
captured in coincidence with the data on the first graph. The full rod
systems tout a narrower change band centered around 42% +/-3

This data shows the
changes inside the piano with Music Sorb.
The graph shows how smooth and small the changes are with this
Chemical control.
|
|
Again the MAX-MIN
range tells a more complete story. The
range for the entire year is just about half of the changes in the room
|
|
The point to point
(morning – evening) data show even better results with less than a 1% change
in the day.

|
Humidity control, I
stress CONTROL vs. just heater rods, does buffer and smooth the changes the
piano will undergo. There still is change. Regular tunings are still needed.
|
|
The smaller smoother
changes will assist is instrument stability and smaller deviation from the
last tuning related to relative humidity.
|
|
Some humidity
control is a good thing.
