How changing the frequency and amplitude affect the sound heardby the listener? higher amplitude results in louder volume and vice versa, while higher frequency results in higher pitch and vice versa

Therefore the level (volume) is proportional to the square of the amplitude

Explanation:

The amplitude of the one sound signal is related to the volume that is heard,

P = A2

 Where P is the power that the volume heard and A the amplitude of the signal.

Therefore the level (volume) is proportional to the square of the amplitude

The frequencies are related to the tone of the sound, the more frequent the more acute the sounds are and the less frequent the more serious is the sound heard.

i guess the game developers wanted to give off a more gamey/cartoony feeling without trying to copy fortnite exactly
