Question regarding sound and Earth's rotation

Click For Summary

Discussion Overview

The discussion revolves around the effects of Earth's rotation on sound perception, particularly in relation to a claim made by proponents of the "Flat Earth" theory. Participants explore whether the speed of sound is influenced by the Earth's eastward rotation and the implications of atmospheric dynamics.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions if speech and hearing change based on the direction faced due to the Earth's rotation and the speed of sound.
  • Another participant asserts that the atmosphere rotates with the Earth, implying that this negates any significant effect on sound perception.
  • A third participant notes that sound perception can be affected by wind speed, suggesting that environmental factors play a role in how sound is experienced.
  • A later reply emphasizes adherence to forum rules regarding discussions on controversial topics like the Flat Earth theory.

Areas of Agreement / Disagreement

Participants express differing views on the influence of Earth's rotation on sound, with some asserting that the atmosphere's motion mitigates any effects, while others highlight the role of wind as a significant factor. The discussion does not reach a consensus.

Contextual Notes

Participants do not fully explore the implications of inertia or other physical principles that might affect sound propagation in relation to Earth's rotation.

Hi guys, I am new to the forum and I have what is probably a simple question for most of you.
Unfortunately a great deal of people I know have suddenly taken up the idea of a "Flat Earth", and they consistently post things that try to contest that a flat Earth is a far more logical idea than a round one. Now that aside someone recently posted this

"If the Earth is spinning eastwards at 1000mph, and the speed of sound is 768mph, does our speech/hearing change depending on which direction we are facing? Lol!"

Now I assume that this may not exactly be the case due to inertia? (Please correct me if I am wrong) but is there a full explanation as to why this is/isn't true, I tried searching for materials but everything I can find only relates to flight times and Earth's rotation.

Any help would be very much appreciated.

Thanks :)

Welcome to the PF, Joe.

That answers your question, and we do not debunk crackpot ideas like Flat Earth here at the PF (that's in the Rules link at the top of the page under Info). Thread is closed.
