The basic and first question in everyone mind is, what is noise cancelling? Noise canceling headphones have become extremely popular recently because they really cut you off from the environment. Noise canceling headphones work on the principle of anti-noise. Sound consists of sound waves with a certain shape (amplitude). Noise canceling headphones measure the ambient noise and respond to it with a signal reversed to the ambient noise. The ambient noise is thus canceled and you only hear what you want to hear. Ideal for on the plane, times when you want to concentrate or simply don’t feel like ambient noise.

There is a difference in the degree of noise canceling between different headphones and price ranges. In general, more expensive headphones also have better noise canceling and reduce ambient noise better (or even completely).

Protect your hearing with our sound-absorbing earmuffs

For the  moment you came, your ears are often hard to endure. A little rest now and then is not an unnecessary luxury. To ensure that your hearing is not damaged, there are  different types of hearing protectors:  earplugs, on-the-ear headphones and over-the-ear headphones. The latter type is also called noise canceling headphones or soundproof headphones.

What does noise cancelling or noise reduction mean?

Noise  canceling or muting  can be done in 2 ways:  passive and active. When we close the  ear canal  through, for example, on-the-ear headphones, we speak of sound attenuation. The surrounding sounds are then less loud. With active noise canceling, the background noise is muffled by a specific mechanism. The over-the-ear headphones have a microphone that measures and analyzes ambient noise. The mechanism then generates a kind of anti-noise (a counter-noise to what has been measured). The combination of both sounds ensures that the monotonous  background noise is muffled.

The benefits of noise canceling

The  biggest advantage of noise cancelling is that it can protect your hearing from loud, annoying sounds as well as excessively loud music volume. After all, disturbing ambient noise is muted, so that you can fully enjoy your music at a normal sound volume. In addition, noise canceling ensures more rest and better concentration.

When should you use noise cancelling headphones?

Noise cancelling headphones are often used in workplaces  where  loud and loud noises are a daily occurrence   , for example printers, workshops, for pilots, etc. But you can also use them when mowing your grass or for loud  leisure activities such  as attending concerts and festivals .

In addition, these sound-absorbing headphones are also used  when traveling  by plane or train. The annoying noise from these vehicles as well as the noisy fellow passengers can cause your hearing to be damaged and you need some rest. It is important to know that these headphones mainly mute monotonous sounds; high frequencies and non-monotonous sounds remain audible.

Such a headphone can also help people who work in an office. After all, muting monotonous sounds promotes concentration. Without the hum of electrical appliances, it is easier to keep your focus on work.

Do you have trouble falling asleep or wake up from street noise or electrical appliances in the house such as a refrigerator or television in sleep mode? Then a noise canceling hearing protector is worth buying. It provides the necessary silence for a good night’s sleep.

 

Hearing protection for children

Not  only hearing for adults, but also that of children are at risk of damage. Babies and children are  more sensitive to loud noises  than adults.

Unfortunately, they are all too often exposed to loud noises such as toys, the volume of the television, household appliances such as a vacuum cleaner, during parties and fireworks. To protect the little ones among us, there are also sound-absorbing headphones for children from 3 years.
