If tubing length is increased
The primary resonant peak will shift downward and the output will increase in the lower frequencies and decrease in the mid and high frequencies. Also the amplitude of the 2nd & 3rd peaks will be reduced
If tubing length is decreased
The primary and secondary peaks will shift upward in frequency. Also the output will decrease in the low frequencies and increase in the mid and high frequencies
Using tubing with a wider internal diameter will
Increase the gain between 1000 and 2000 Hz and decrease the gain in the lower frequencies
Using tubing with a narrower internal diameter will
Increase in the lower frequencies and decrease the gain in the higher frequencies
