App Description:
This app is a simulator, it has 2 sound frequency generators, its target is to make demonstration for cases where ”sound+sound=silence” which occurs due to beat phenomena, the user can control the frequency for both sources.
Details:
The app includes the following:
1- Very Detailed description of “what is the beat phenomena” using figures and animation.
2- Simulator that has 2 independent sources of sounds representing one frequency each, and are user controlled:
-The user will be able to configure frequencies from 200hz up to 20Khz.
-Play the sounds for both sources independently or simultaneously.
-Check the summation of both sounds.
-User will be able to notice the beats of “silence” when 2 frequencies are near to each other.
3- The Same Simulator can be used as frequency sound generator.
4- One Final experiment that represents the different ability for people with different ages to hear high frequencies.
