In real life we have "natural" ultrasonic frequencies ... they do no harm; we can't hear them.
In audio life (!) we have equipment like power amps and transducers that distort in various ways that are not "natural" at all, one being intermodulation distortion. However, IM distortion from ultrasonic frequencies can appear in the audible band. If the ultrasonic frequencies are absent then your equipment does not generate this added distortion. So it may be useful to use 44/48kHz as opposed to higher sampling rates.
