Always talking on a cell phone can increase the chance of having brain cancer. A noise cancelling headphone uses a battery to operate. It emits frequency to interfere the noise in the background and it is 85% noise cancellation. I am wondering whether it will have the same effect as a cell phone which can increase the chance of having brain cancer if we talk on it too often. I have ear pain and that’s why I don’t want to use ear plugs.

No.

Active noise cancellation headphones emit in the audio range (and phase inverted version of the surrounding noise). Telephones emits in the hundreds of millions of hertz (cycles/sec) range. Which heats up and vibrates your braincells possibly eventually leading to their mutation and a tumor in some people.

Basic rule of thumb, if its a natural range, natural food, or a naturally occuring chemical it probably won’t give you cancer.

If its man-made, a frankenfood, or is made by a guy in a lab coat it may give you cancer.

If you get ear pain it could be a result of the pressure from the firm fit of the ear plug or the volume. Use it at a reasonable volume (snug headphones can cause headphone cause they direct sound pressure right onto the drum with no ventilation of pressure). Rest your ears. Keep them dry. Don’t use cotton wool buds (Q-tips) inside your ear. Clean them with a MILD 3% hydrogen peroxide solution if they get waxy using an eyedropper) MAKE SURE ITS A DILUTE 3% NO STRONGER.
