A “showy” custom-built car has two brass horns that are supposed to produce the same frequency but actually emit 263.8 and 264.5 Hz. What beat frequency is produced?

This is College Physics Answers with Shaun Dychko. The two brass horns on this Showy car emit frequency f 1 of 263.8 hertz and frequency 2 of 264.5 hertz and the question is what will the beat frequency of the combination of these two frequencies? So the beat frequency is the absolute value of the difference between the two frequencies. So it's the absolute value of 263.8 hertz minus 264.5 hertz which is a beat frequency of 0.700 hertz.
