Beats of Sound

Visualising of Beats Using Visual Analyser

Theory:
Beating is the periodic variation amplitude at a given point due to the superposition of two waves having slightly different frequencies.

App./Software:

• Frequency Sound Generator
• Visual Analyser Software

Frequency Sound generator is installed from playstore.
f1 = 1700 Hz, f2 = 1529 Hz (set the frequency at any
 different frequencies)

Visual Analyser shows the beats from the two different frequencies. Later, we can compare the Beat of Sound from the Visual Analyser and the Frequency Sound Generator

 Data Analysis:

A simple calculation to compare the Beat from FSG and VA

Conclusion:

• The beat frequency obtained from the Visual Analyser data reproduces the value calculated from Frequency Sound Generator within 1.53%

The Visual Analyser Sofware has been used to measure the beat frequency form by the waves that generate by Frequency Sound Generator

The use of Visual Analyser and Frequency Sound Generator in Physics Teaching aid to teachers and students in understanding the beat frequency.
