What beat frequency will occur when a 370 hz and a 374 hz sound source are sounded together?

The beat frequency occurs when two sound waves of slightly different frequencies are played together, and it is calculated by taking the absolute difference between the two frequencies. In this case, the beat frequency is |374 Hz - 370 Hz|, which equals 4 Hz. Therefore, a beat frequency of 4 Hz will be heard when the 370 Hz and 374 Hz sound sources are sounded together.
