SRB's velocity flows are beyond MACH, so "shock wave" is technically correct.

A speaker's velocity flows are well under MACH, so "shock wave" is incorrect. "Sound wave" is correct.

...the harmonics of the SRB are quite similar to a tubular loudspeaker, and the mathematics for both are the same.
They are most certainly not the same!

Here's an online loudspeaker graphic calculator. Here's a collection of many more, most of which show the math. This $248 book entitled, Theory & Design of Loudspeaker Enclosures is chock full of math. In fact, unless you're either a mathematician, a physicist, or an aero engineer, you probably won't understand much of it.

Here's a web page showing the mathematics typically used in loudspeaker Transmission Line, that is, a driver in a tube, the closest parallel between a speaker and an SRB.

Please show me the online SRB calculator, or the mathematics used in SRB design.

Thank you.
