Now you take C, which is tuned at >305 Hz, which means at least 306 Hz (in integer steps...). If B was 299 Hz, then, together with C, which is higher tuned than A, the Beat frequency would increase to at least 306 Hz - 299 Hz = 7 Hz.

WebWave Interference and Beat Frequency. An interactive demo which enables you to both see and hear the result of adding two sine waves of different frequencies.
