SUMMARY

Acoustic length refers to the effective length of a column of air in a musical instrument, specifically how sound waves perceive this length compared to human measurement. It is crucial for understanding the behavior of sound waves in instruments like native American flutes. The concept is influenced by factors such as end correction and the tone-hole lattice, which modify the perceived length of the instrument's air column. Mastery of acoustic length is essential for instrument makers and musicians aiming for precise sound production.

PREREQUISITES
  • Understanding of sound wave propagation
  • Familiarity with musical acoustics
  • Knowledge of end correction in pipes
  • Basic principles of tone-hole design
NEXT STEPS
  • Research "End correction in musical instruments"
  • Explore "Tone-hole lattice effects on sound"
  • Study "Acoustic properties of air columns"
  • Learn about "Sound wave behavior in different mediums"
USEFUL FOR

Musicians, instrument makers, acoustics researchers, and anyone interested in the physics of sound in musical instruments will benefit from this discussion.

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"?

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:
