# Math Help - Superpostiion of waves

1. ## Superpostiion of waves

Suppose listen to two voices as follows (where volumes are in $[0,1]$):

Voice 1: volume: 1, frequency = 7 Hz

Voice 2: volume: 0.35, frequency = 3 Hz

How are the waves combined? Does one interpret it as a 4 Hz wave? Do volumes play an effect?

Model each voice by an appropriate sine function and then add the functions.
