Subject: [Harp-L] side vent test discussion

Dave asked:  "Did anybody hear a tonal difference? If so, what was  it like? 
There is a difference in volume, I couldn't really hear much of a  volume 
shift, but I could see a slight change graphed, so it's there."  


yes.  clear as a bell ;)  I'm one of the 19 who heard it  instantly. 
Actually, it sounded as though the sound was almost being 'bent', but  it was being 
done by blocking and unblocking the vent.  Very strong  difference (at least to 
my untrained ears)...when your finger came off (and yes  I could easily hear 
each time you blocked and unblocked the vents)...the sound  'popped' louder, 
and was fuller; then more muffled when the vents were being  covered.

I just called that guy whose answer I had slight doubt what he meant  and got 
clarification. That's 19 of 19 who correctly identified the sample with  
side-vent manipulation. There were also about seven others who responded after  
someone posted their findings on slidemeister, all of them correctly named the  
manipulated sample as well.

I'm going to do this same test with a Marine  Band. I expect those results 
won't be as one-sided. The prewar Seydel Bandmaster  has side vents on steroids 
compared to the MB. 

Did anybody hear a tonal  difference? If so, what was it like? There is a 
difference in volume, I couldn't  really hear much of a volume shift, but I could 
see a slight change graphed, so  it's there.
