Wearing Noise-Cancelling Headphones to Protect Your Ears While Riding the Subway!

With the removal of headphone jacks from mobile phones, Bluetooth headsets have become a must-have companion for mobile phones. Compared with ordinary Bluetooth headsets, noise-cancelling headphones have an additional noise-cancelling function, but the price is often several times more expensive. Is the experience improvement brought about by this expensive price worth it? Should you choose a normal Bluetooth headset or a more powerful noise-cancelling Bluetooth headset? These questions are quite troubling.

Today this blog will give you some answers.

How do noise-cancelling headphones work?

When it comes to noise reduction, the first thing that comes to your mind may be to close the doors and windows tightly so that noise can’t get in, and the room will naturally be quiet.

This is called physical noise reduction, and it is the most common noise reduction method in our lives. Wearing earplugs to sleep at night also falls into this category.

However, there are two drawbacks to physical noise reduction: First, it can significantly reduce high-frequency noise such as car whistles, but it is not so obvious to medium and low frequencies such as wind. Second: it also shields the human voice, so it is quite dangerous to use physical noise reduction methods such as earplugs when going out.

Noise-cancelling headphones are not so primitive. It adopts the active noise reduction method: first use the microphone to collect the noise in the environment, and then use the processor to calculate a sound wave opposite to the noise to cancel the noise, so that what our ears hear is a world with almost no noise!

Moreover, the noise reduction effect of active noise reduction on medium and low frequency noise is not inferior to that of high frequency, and the noise reduction effect is first-class in any environment~

Can noise canceling headphones protect your hearing?

Before answering this question, let's look at a common scenario.

On the subway, if you wear wired headphones, do you turn up the volume extra high to hear the music clearly? At this time, some people do not feel that the ear is particularly uncomfortable, and based on this, they feel that there is no damage to the hearing. But when you go back to your quiet home and listen to the volume set on the subway, you will feel harsh and unbearable.

This phenomenon is called auditory masking. The human ear has a hearing threshold within which sound can be heard. This hearing threshold varies with the background ambient noise.

For example, the hearing threshold will be raised in a noisy environment. At this time, people can hear high-volume sounds, but cannot hear low-volume sounds, so we unconsciously turn up the volume of our headphones to listen in the subway.

However, generally on the subway, if you want to listen to music clearly with semi-in-ear headphones, the volume is often adjusted to more than 100dB. According to the recommended safe weekly exposure to sound given by the WHO, listening to a sound of 105dB for more than 10 minutes per week will cause irreversible hearing damage.

So, will wearing them protect your ears?

Of course!

Noise-cancelling headphones can eliminate external noise, reducing the hearing threshold of our ears and allowing us to hear low-volume sounds. So on the subway we can also listen to low-volume ear-friendly music~

In addition, wearing noise-cancelling Bluetooth headphones, the world is instantly quiet, you can hear every detail in the music, and immerse yourself in the sound wave of singing. This experience is also extremely beautiful~
