Sound wave propagation and doppler shift wrt the medium

Click For Summary
SUMMARY

The discussion centers on sound wave propagation and the Doppler shift concerning the medium, specifically in scenarios involving wind. Participants explore how sound waves are perceived differently by two individuals positioned ten paces apart when wind affects the medium. It is concluded that the person downwind will hear the tone at a higher frequency due to the wind aiding the sound wave's travel, while the person upwind will perceive a lower frequency. This phenomenon illustrates the impact of the medium on sound wave behavior.

PREREQUISITES
  • Understanding of sound wave propagation principles
  • Familiarity with the Doppler effect
  • Basic knowledge of wave frequency and pitch
  • Concept of medium influence on sound transmission
NEXT STEPS
  • Research the mathematical formulation of the Doppler effect in moving media
  • Explore sound wave behavior in different mediums, such as air and water
  • Study the effects of wind on sound propagation in outdoor environments
  • Investigate practical applications of the Doppler effect in technology, such as radar and sonar
USEFUL FOR

Physicists, acoustics researchers, audio engineers, and anyone interested in the principles of sound wave behavior and the Doppler effect in various mediums.

In contemplation and research regarding another thread's question about the asymmetry of doppler shift wrt the medium, I find myself trying to imagine two people talking... or perhaps better yet matching pitch. In still air with both people facing each other at ten paces of course they would agree that both are right on key.

If the wind were to blow the person downwind would hear the tone sooner or later than the person upwind and higher or lower pitch?

Hi there :smile:

what tone? and where is it placed relative to the 2 people ? and what is the actual direction of the wind
You never mentioned any tone source in your initial scenario

draw a pic with people and tone source positions and wind direction

Hi and thanks in advance...

I am inclined to believe the sound waves would travel faster with the motion of the medium increasing the frequency heard downwind?
