SUMMARY

The discussion centers on the relationship between loudness intensity and the physical properties of sound waves, specifically focusing on maximum displacement, speed, and frequency. It is established that maximum displacement (amplitude) increases with loudness intensity, which directly influences the speed of the sound wave. Additionally, the frequency of the sound, defined as the number of vibrations per second, is confirmed to be related to the musical note produced. The participants emphasize that these principles align with current physics understanding.

PREREQUISITES
  • Understanding of sound wave properties, including amplitude and frequency.
  • Basic knowledge of physics principles related to motion and waves.
  • Familiarity with the concept of loudness and its measurement.
  • Knowledge of how sound waves interact with mediums.
NEXT STEPS
  • Research the relationship between amplitude and loudness in sound waves.
  • Explore the physics of sound wave speed and its dependence on medium properties.
  • Learn about the mathematical relationship between frequency, wavelength, and speed of sound.
  • Investigate how musical notes correspond to specific frequencies and amplitudes.
USEFUL FOR

Students of physics, audio engineers, musicians, and anyone interested in the scientific principles of sound and music production.

Surely, its maximum displacement A increases.

But what about its speed? Increases, decreases, remains the same?

And what about the number of the vibrations of its maximum displacement per sec? They increase or decrease or remain the same? This number is the frequency of the music f, or not?

Please post only those who are certain of the answer, or certain of what today's physics claim on this.

The number of vibrations per second is the musical note.

The loudness is determined by the amplitude (size) of the movement.

So, if you want something to move further in the same amount of time, you have to move it faster.

It ain't Physics - it's just plain common sense.
