ttonon Posted March 20, 2013 Share Posted March 20, 2013 Adrian, I think you controlled bellows pressure quite well in the recordings you made. If you compare the traces in Figure 1 of the .doc file I attached above, it's obvious that the the inboard reeds have a much lower amplitude (volume) than the other reeds, and the most obvious guess why this is so probably has something to do with the doubly long aperture length. I'm assuming that the inboard notes you played do not have the chamfered aperture you show a picture of. As I mentioned to Mark, it's difficult to theoretically explain how such a long aperture would affect sound spectrum, but the effect on sound volume is intuitively easier for me to make guesses about. Thus, the apertures in your pictures were perhaps chamfered as an effort to increase sound volume. Tom Quote Link to comment Share on other sites More sharing options...
