Beat Frequency: How Does it Change With Pure Tone Increase?

Click For Summary

Discussion Overview

The discussion centers around the concept of beat frequency generated by two pure tones and how it changes when the frequency of either tone is increased. It explores the relationship between the frequencies of the tones and the resulting beat frequency, focusing on theoretical understanding.

Discussion Character

  • Conceptual clarification, Technical explanation

Main Points Raised

  • One participant states that the beat frequency is calculated as Fb = F1 - F2, suggesting that increasing either frequency could affect the beat frequency in different ways.
  • Another participant agrees with the initial logic presented, indicating that the reasoning is correct.
  • A further contribution clarifies that the effect on beat frequency depends on whether the change in frequency brings the two tones closer together or moves them further apart.

Areas of Agreement / Disagreement

Participants generally agree on the logic behind the relationship between frequency changes and beat frequency, but the discussion does not explore any competing views or unresolved questions.

Contextual Notes

The discussion does not address specific assumptions about the range of frequencies or the conditions under which the beat frequency is calculated.

Who May Find This Useful

This discussion may be useful for individuals interested in sound theory, music acoustics, or those studying the effects of frequency changes on auditory perception.

if i play two pure tones together, i create a beat frequency. if i increase, any of the two pure tones, what happens to the beat frequency?

heres my logic as to why the beat frequency can go either way: Fb = F1-F2, so if you increase F1 it increases and the opposite if you increase F2.

how wrong am I?

T@P,

you are correct.

TRoc
 
In other words, it is a matter of whether changing the frequency of one note moves the frequencies close together or further apart.
 
wow

that means I got the question right on the test! YAY
