Understanding Frequency in Open and Closed Organ Pipes

Click For Summary
SUMMARY

This discussion clarifies the frequency characteristics of open and closed organ pipes. For an open organ pipe, both odd and even harmonics are present, while a closed organ pipe only supports odd harmonics. The correct representation of these frequencies is confirmed, emphasizing the unique harmonic behavior based on the pipe's configuration.

PREREQUISITES
  • Understanding of harmonic series in acoustics
  • Basic knowledge of sound wave behavior
  • Familiarity with organ pipe construction
  • Concept of open vs. closed boundary conditions in physics
NEXT STEPS
  • Research the harmonic series in open and closed pipes
  • Explore the mathematical representation of sound waves
  • Learn about the physical properties of sound in different mediums
  • Investigate the design and acoustics of musical instruments
USEFUL FOR

Musicians, acoustics engineers, physics students, and anyone interested in the principles of sound production in musical instruments.

I have to draw frequency on an open and closed pipe. The top horizontal row is open organ pipe and the second horizontal row is a closed pipe. I have draw the frequency of sound on these but the open entrance of the sound is what is confusing me. Are these correct?

Yup, they are drawn correctly. Note that for the open pipe, the even harmonics also work, it's just for the closed pipe that you only have to consider the odd ones only.
