Readers Question 3: Shell Thickness

So the second of 6 questions from Sophie, what difference does the thickness of the shell make. Well this is actually quite an easy question. As the thickness of a shell increases, the volume, attack and dryness increases. This is due to the fact that a thin shell is more easy to vibrate and so vibrations travel more through the material and so ring out a lot more. The thicker a shell is the less space inside the shell so the pitch goes up, and with a heavier shell to vibrate it dries out the sound as vibrations travel for a shorter period of time. Also because the shell is thicker the shell is more dense and so the volume is raised. So there you go, the reason between the thickness in shells :)
