Pitch can exist with no tone heard at that frequency, unlike phantom tones
Evidence
Listen carefully for the presence of a 200 Hz sinusoidal partial with only partials 400, 600, 800, 1000, 1200, and 1400 present. You won’t hear a 200 Hz partial at low sound intensities, yet a 200 Hz pitch will prevail. The 200 Hz partial is not there in the original sound, nor is it created for us by any part of the hearing system from the outer ear to the auditory cortex. What is created by that system is the sensation we call pitch. Pitch is not partial. — Eric J. Heller, Why You Hear What You Hear- An…, 2031 (

Another interval, f2 = 2048 and f1 = 3072 Hz (and analogous intervals), is remarkable in that, first, the difference tone f = f1 – f2 = 1024 and the combination tone f = 2f2 – f1 = 1024 are the same; thus what Koenig termed the lower beat tone (the difference tone) and the upper beat tone (the combination tone) coincide. This combination has loudness beats at 1024 Hz. If the higher frequency f1 is raised by A Hz, the difference tone should increase by A Hz, but the combination tone should decrease by A Hz. Indeed, as f1 = 3072 is lowered by hand, as is possible in the MAX patch Partials, one hears both rising and falling phantom tones (a rising combination tone and a falling difference tone) interfering with each other, causing beats when they are still relatively close in frequency. When f1 = 3073 Hz, there should be two beats per second, and that is what is heard. This is also the frequency of the waveform beats. If, on the other hand, the lower frequency is raised by A Hz, the difference tone should decrease by A Hz, but the combination tone should increase by 2 A Hz, implying a beating of between them of 3 A Hz. That is heard also. Quite an instructive example! We are feeding our ears only two pure tones, both above 2000 Hz, yet we are discussing the easily audible beating of two phantom tones, both around 1000 Hz! — Eric J.
