Do you know where people use noise-cancelling headphones the most? Airplanes, of course. So it’s no surprise to us that noise-cancelling headphones started in the aviation sector. Noise-cancelling headphones were created for pilots to communicate with the control tower and other pilots without having to yell over the engine’s roar. 

The first noise-cancelling headphones were created in 1980 by Dr. Amar Bose, a professor of electrical engineering at MIT. He was also the founder of the Bose Corporation. The headphones were bulky and expensive, but they were very effective in cancelling noise.

Nowadays, noise-cancelling headphones have become much smaller, more comfortable, and affordable. You can find them in many different styles, such as earbuds, on-ear, and over-ear headphones. Active noise cancellation is used in various settings such as offices, factories, construction sites,s and many more.

The Basics of Active Noise Cancelling Headphones

The Basics of Active Noise Cancelling Headphones

Active noise cancelling is a technology that is built into headphones. It uses microphones to pick up on the external sound waves and then creates inverse waves that are 180-degrees out of phase.

The noise-cancelling circuitry keeps track of the sound’s frequency and loudness before producing an anti-sound. The latter is combined with the original sound and played through the headphones. The background noise can be reduced, allowing you to focus on the audio you want to hear.

It now works in noisy environments with low to mid-frequency noises such as trains, airplanes, traffic noise, etc. However, another type of noise-cancelling technology is used in headphones, known as passive noise cancelling.

Passive vs. Active Noise Cancelling Headphones

Passive noise-cancelling headphones are designed to physically block out sound waves by using materials that do not allow sound vibrations to pass through them, such as memory foam, silicone, and other types of soft foam. These headphones are less expensive, but they are not as effective as active noise-cancelling headphones.

On the other hand, active noise-cancelling headphones use a microphone to pick up on sound waves and then create an inverse wave 180 degrees out of phase. The noise-cancelling circuitry keeps track of the sound’s frequency and loudness before producing an anti-sound. The latter is combined with the original sound and played through the headphones. The background noise can be reduced, allowing you to focus on the audio you want to hear.

Active noise-cancelling headphones are more expensive, but they are worth the investment because they are much more effective at reducing noise.

Is Active Noise Cancelling Bad for Your Ears?

The simple answer is no; active noise cancelling is not bad for your ears. However, some people may experience significant discomfort due to using noise-cancelling headphones.

A great set of noise-cancelling headphones is a nice reprieve for most of us in an increasingly noisy environment. It may be satisfying to filter out all of daily life’s unwanted distractions. It’s enticing just to hit the noise-cancelling button and tune out the rest of the world.

But for some people, using noise-cancelling headphones can cause headaches, dizziness, nausea, and fatigue. This is because our bodies are designed to process sound in a specific way, and when that process is disrupted, it can lead to these negative side effects.

However, it all comes down to the volume you are using your noise-cancelling headphones. If the volume is too loud, it can damage your hearing over time. But if you keep the volume at a moderate level, you should be fine.

Active noise cancelling, on the whole, has no harmful impact on your hearing. If you turn on the ANC, you could hear a minor hissing noise, but that’s it. This, however, might be annoying to some users and possibly cause dizziness. In this situation, it’s best to avoid using it too much or turn off ANC if the setting isn’t too loud. Keep in mind that this hissing noise is not harmful to your ears.

Another thing to keep in mind is that noise-cancelling headphones do not generate radiation like our cellphones.

Active Noise-Cancelling Headphones: Safety Concerns

Active Noise-Canceling Headphones: Safety Concerns

Despite the known advantages of active noise-cancelling, there have been various user complaints on safety-related issues, regardless of whether they are premium or budget-friendly. Let’s go over some of the safety concerns you should bear when using these headphones.

▶Ear Pressure

If you’ve ever used noise-cancelling headphones, you may have noticed a change in the pressure in your ears. This is normal and not harmful. However, some people may experience pain or discomfort due to the ear pressure. The ear pressure, in particular, is comparable to what one might experience on an airplane that is ascending. Even though noise-cancelling headphones are designed for airplane use, some people still report feeling pain in their ears.

The ear pressure we experience while flying is caused by air density variations within and outside the ears. The inner ear vibrations are less when the air density within the ears is higher. Thus you hear fewer low-frequency noises. The converse is also true, so you can hear a difference in noise when the airplane’s engines are turned off.

While the sensation of ear pressure from using noise-cancelling headphones is normal, it’s essential to be aware that some people may experience pain or discomfort as a result.

▶Tinnitus

Tinnitus is a condition that causes you to hear ringing, buzzing, or other noise in your ears even when there is no external sound. It can be intermittent or constant, and it can vary in loudness. Tinnitus is often caused by exposure to loud noise, but it can also be caused by certain medications, head injuries, and other health conditions.

It’s a typical condition that may affect people of different ages and is caused by anything that interferes with or destroys the delicate inside tissues of the ears. Many individuals have complained about tinnitus as a result of wearing ANC headphones, but there is no strong evidence to prove this claim. The increased noise suppression of ANC headphones may be a credible explanation for tinnitus perception.

On the other hand, ANC headphones are advised for tinnitus patients and the prevention of tinnitus. Since the efficient ambient noise-cancelling feature eliminates the need for users to boost the volume of the headphones in loud surroundings, subsequent tinnitus attacks are reduced or prevented.

▶Ear Fatigue

Even though ANC headphones have been designed to be as comfortable as possible, some users may experience ear fatigue. Since ear cups of the headphones create a seal around the ears, which causes the ears to feel tired. It is often recommended to take a break from using the headphones every few hours to give your ears a rest.

Some ANC headphones come with different-sized ear cups so that you can find a better fit for your ears. There is also a type of ANC headphone with an open-back design, which can help reduce ear fatigue.

▶Dizziness and Nausea

Dizziness is a feeling of lightheadedness or vertigo, while nausea is an uneasiness of the stomach that often comes before vomiting. Both dizziness and nausea can be caused by many different things, including medications, diseases, and disorders. Some people have reported feeling dizzy or nauseous after using noise-cancelling headphones.

There are a few possible explanations for this. First, the change in ear pressure that occurs when you use noise-cancelling headphones can sometimes cause dizziness. Second, some people may be sensitive to the hissing sound produced by the noise-cancelling feature. This sound is usually only audible to the person wearing the headphones, but some people may be sensitive to it.

▶Interference with Assistive Devices

This is more of a concern for people who rely on assistive devices, such as hearing aids or cochlear implants to hear. Some noise-cancelling headphones can interfere with these devices and cause static or other noise. If you use an assistive device, it’s essential to check with the manufacturer to see if there are any known issues with using noise-cancelling headphones.

▶Sleep Issues

A sound sleep is essential for good health, but some people find that noise-cancelling headphones can disrupt sleep. This is because the hissing sound produced by the noise-cancelling feature can be disruptive. Choosing a model that doesn’t produce this sound is essential if you’re using noise-cancelling headphones to help you sleep. You may also want to try using them for a shorter period to see if that helps.

How Can You Protect Your Ears
