I saw 10cm bore internal diameter ,outer diameter is 13 cms and 109cm bore lenght , there is a only a 18mm diameter hole at the bottom and mouthpiece - 2.9 cms hole- giant shakuhachi at adam conway facebook page. less than 100HZ output.
I thought I can make a 10 cms , read again 10 centimeters long bore and 10 cms bore internal diameter shakuhachi with 35 HZ output.
You must have to cut 10 cms diameter plexiglass round 4mm thick diaphram and you must create a internal housing this round plexiglass piece which sits in loosely and escapes air from diaphram corners when it is a barrier to air.
When you apply high pressure air , anyone in 30 miles circle can hear you :)
I believe , after this post , someone will make human lung pressurable shakuhachi with this technology :) I am not joking , its been used at ships very long time and you can search youtube for DIY Ship Horn !
Its totally applicable - god knows how - wind instruments and may be kick drums.
This is my idea, its protected by copyright for 100 years and nobody can not patent it.
