Organ Pipe Design

Application ID: 14729

This app demonstrates the following:

  • Using a Java® utility class for combining several waveforms and for playing sound
  • Using tables for presenting results

The app allows you to study the design of an organ pipe and then play the sound and pitch of the changed design. The pipe sound includes the effects of different harmonics with different amplitudes.

The organ pipe is modeled using the Pipe Acoustics, Frequency Domain interface. The app allows you to analyze how the first fundamental resonance frequency varies with the pipe radius and wall thickness, as well as with the ambient pressure and temperature.

In the app you can find the full frequency response, including the fundamental frequency and the harmonics. With a method written in Java® code, the app detects the location and amplitude of all harmonics in the response, thus extending the analysis beyond the built-in functionality of the COMSOL Multiphysics user interface.
