If you don't have them installed, you may need to grab the VB6 Runtimes - Windows XP already has them.


Notice: Minor error found in earlier versions of boxnotes
The driver-to-wall resonances shown in boxnotes versions 2.82 and earlier were wrong
They were calculated on the assumption that the driver acts as the open end of a resonant pipe
These experiments show that it acts as a closed end
The resonances are thus half-wave rather than quarter-wave and the frequency need to be doubled as a result
This error has been corrected in the current version (V3.00 onwards)
