I've written to James Boyk at
boyk@caltech.edu in hopes of getting some answers to my queries, but alas, I have not received a response, thus, I have decided to post my 2 questions here.
As some of you know, Mr. Boyk has measured a muted trumpet's 100 and something 's harmonic out to around 102Khz. But is that the highest measurement from any standard musical instrument? I dunno.
And Peter P. has shared his knowledge about a grand old pipe organ with a measured low of around 8.5 Hz, but again. has any standard musical instrument been measured to be lower? I dunno.
Now these questions have nothing to do with hearing, only measurable frequencies of what actually exists and has been measured from standard musical instruments. It has nothing to do with db downpoints, again, it just has to do with what has been measured and what frequencies actually exist.
In these questions we are also excluding any issues of gear chain, recording, playback, and what people are supposedly able to hear, so these are 2 questions based solely upon scientific measurements using precision test equipment of frequencies that actually exist.
If at all possible, I would hope any answers could be expressed in Hertz.
Having said all that, here are the two questions:
1) From any given standard musical instrument, what is the highest frequency that has ever been measured?
2) From any given standard musical instrument, what is the lowest frequency that has ever been measured?
