As wireless technology has become almost unavoidable, another question has emerged: Could the electromagnetic fields produced by mobile phones, Wi-Fi, Bluetooth and other wireless devices affect tinnitus? It is a question worth investigating. But it is also an area where personal experiences, scientific evidence and speculation can easily become mixed together. The current evidence does not establish that everyday wireless exposure causes tinnitus. At the same time, researchers have investigated the possibility, and there are still questions about exactly how radiofrequency exposure interacts with biological systems. So what do we actually know? What...
