We all know that when listening to music or watching videos, many people like to put on a headset, this is because headphones can help isolate some of the outside world sound, so that we can quietly concentrate on listening to music or watching video. Especially now technology is more and more developed, almost everyone has one or even two more cell phones. Usually when we walk in the street, you may find a lot of people walking with headphones. In the bus, there are also some young people will sit in a chair with headphones to listen to music. Then on noise reduction headphones, we should have heard of it.

 

The current anti-noise products are using cotton, ear cotton, sponge, silicone, noise earplugs and other physical for noise reduction, you can isolate part of the noise, but still a lot of noise can’t be eliminated, especially low-frequency roaring is almost hard to be eliminated. And wear a long time the ear will be swollen pain, the damage to ear and body is quite serious, only the real noise reduction effect of the active noise reduction headphones can play a role in offsetting noise and protecting the ears.

 

Noise reduction principle

The principle of active noise reduction headphones is through the audio receiver (such as micro-microphone) and anti-noise output chip to receive and analyze the external noise and produce the opposite noise, mutual weakening or offset, to achieve the purpose of shielding noise. Both to offset the external noise, but also to protect the ears and physical and mental health. So if you want to buy anti-noise headphones need to choose the real noise reduction effect of the active noise reduction headphones. But now the real noise reduction effects of the active noise reduction headset prices is hundreds of dollars, even a few thousands of dollars and while the effect is actual bad.

 

Precautions

Long-term use of the headset may cause the earwax to be raised into the middle ear while the earplug is inserted into the ear canal, which can cause tinnitus, weaken hearing, pain, or bacterial infection. Anti-noise earplugs are also likely to be the triggers of otitis media, because in the warm, humid environment, many bacteria will be more prosperous breeding. If you wear anti-noise earplugs, remember usually to regularly clean up the earwax, slow to plug, to avoid eardrum injury caused by excessive pressure, after using should also slowly pull it out.

Soaked with warm water before softening into the ear canal, can cause ear canal pain to cannot be continuous effective mute and low cost use. Silicone structure earbuds, although airtight and non-porous, but because of its rubber after the rebound hardness and adult different types of ear canal in full compliance with the probability of small, it will cause pinhole leakage or fine hole leakage, Gas sound effects to reduce the noise ear down about twenty or thirty decibels, the ear canal wall bending soft, blocking the ear there will be ear swelling and earplugs and even sleep in the pain side of sleep pressure, cannot effectively achieve long-term comfort and quiet effect, And the ear wall does not meet the ear to bring ear swelling and swelling, cannot be stuffed into long-term use, noise reduction sleep quality.

 

Sponge earplugs: low-pressure foam material, anti-noise earplugs smooth surface is made of high elastic polyester material, slow rebound, the use of ears when there is no pain, sound effects between 25dB-40dB. The earplugs are ideal for nightly sleep, but because of the slow rebound effect after cleaning it cannot be used repeatedly. In general, sponge earplugs are disposable. But with the development of science, as of now there are some sponges earplugs can be used repeatedly for more than six months and can be scrubbed.

 

Wax earplugs: wax ear buds are the originator of anti-noise earplugs, which can be softened by hand and made into a shape suitable for the ear canal. But the disadvantage is not enough health, as wax may also remain in the ear canal, not easy to clean. And wear a long time the ears will have the feeling of pain. Use: 1 rub fine, the ear buds will be twisted into the strip, rub the more delicate the more easy to wear. 2. Plug in, pull up the ear corner, so than the two-thirds into the ear canal. 3. Hold down and hold the ear buds for about 20 seconds until the earplugs inflate and block the ear canal. 4. Pull out, remove the earplug after use, the earplug gently pull out.
