How noise cancellation works is that, when there is any background noise, the noise cancellation technology does not attempt to eliminate it, instead it counters it by sending another stream of sound, so that the ear will hear but brain won’t be able to process it to make it audible.
Since the sound and the “counter sound” are still hitting your eardrum, this can result in an odd sensation. Your ear is processing the sound, but your brain isn’t registering it. Since the inner ear controls balance, this will produce a dizzying effect in some people.”
Launch your Settings app with a tap, then tap the General button. Next, find the Accessibility tab and tap there. Swipe down to the Hearing section to find the Phone Noise Cancellation toggle. Tap on the switch to the right to set it Off.
In iPhone this can be turned off following the below settings
