What Is Acoustic Length in Musical Instruments?

[beaverflutes]

Hi, I'm not sure if this is the correct forum, or even the correct website but you all seem to know what you're talking about! I make native american style flutes, and have recently become interested in the physics of sound and soundwaves, etc.

I've done well in my research, but have come across some information that contradicts each other. I just need a small clarification.

What exactly is the "Acoustic Length"?

What exactly is the "Acoustic Length"?

When it comes to the question: "how long is a pipe really?", soundwaves experience things differently from humans. Acoustic length is the length of a column of air (or, ofcourse, any other medium able to propagate sound) as seen from the perspective of the pressurewave traveling through it.

If you haven't already, you might want to look into End correction of a pipe and Tone-hole lattice.

Hoping I'm helping, not just sucking eggs... :shy:

Acoustic length refers to the physical length of a sound wave or the distance it travels in a specific medium. It is a measure of the wavelength of a sound wave and is typically measured in meters. In musical instruments, such as flutes, the acoustic length is an important factor in determining the pitch and tone of the instrument. Longer acoustic lengths will produce lower pitches, while shorter lengths will produce higher pitches. Additionally, the material and shape of the instrument can also affect the acoustic length and therefore the sound produced. I hope this helps clarify any confusion you may have encountered in your research.
