![]() ![]() There are barely any regulations on the matter, and it is not a commonly discussed issue. That said, the WHO (World Health Organization) suggest the upper limit of continuous exposure for the general public be 40 mT.Īs far as we know, there's no solid evidence to suggest that the magnets in headphones are harmful or harmless to humans. The negative effects of the electromagnetic fields generated by our household devices, including headphones, are minimal. Stronger magnetic fields, like those produced by magnetic resonance imaging (MRI) machines (in the 0.5 – 3.0 Tesla range), can trigger nausea, dizziness and a metallic taste in the mouth, but these effects are temporary. ![]() The Earth's natural magnetic field does cause any harm, and its effects are practically omnipresent. The tesla is an SI unit for magnetic flux density with base units kg/(s 2 This means it is not varying rapidly at any given point (including at a human body). The magnitude of the Earth's magnetic field at its surface ranges from 25 to 65 microteslas and is considered static at a single point. In fact, due to electromagnetism, any flow of electrical current has a coinciding magnetic field. To add to the everyday magnetic fields surrounding us, humans have created artificial magnetic fields with power lines, electrical appliances, and many other commonplace technologies. Furthermore, our very own nervous systems produce electromagnetic fields. Humans have evolved with the Earth, so we've evolved to survive and thrive in magnetic fields. A spinning ball of liquid iron in our planet’s core produces a huge magnetic field with north and south poles. Let's start by stating that the Earth itself is like a giant magnet. The sources are listed at the end of this article. Much of the information in this article has been sourced from professionals that know much more than I do in the fields of human health and magnetic fields. Rather, I am an audio engineer and blogger. In this short article, we'll discuss the effects of magnetic fields on humans and the safety measures we should take when wearing headphones and earbuds.īefore we begin, I should state that I am not a medical professional, nor am I a scientist that studies and experiments with magnetic fields. However, the sound levels produced as a result of these magnets may cause hearing damage if driven too high. If you've ever wondered how your headphones or earbuds work, you've likely researched and learned that they have magnets in their design that help to convert audio signals into sound.Īre the magnets in headphones/earbuds bad for you? There are no studies suggesting that the magnets and the relatively small magnetic fields in headphones negatively affect your brain, ears, and/or body. ![]()
