About Noise Cancelling Headphones
Noise cancelling headphones are headphones that are powered by batteries used get rid of unwanted or ambient noise in the surrounding of a listener. To put simply how they work, noise cancelling headphones have minute inbuilt microphones which listen and record in real time unwanted noise or sounds in the environment of a listener. The recorded frequencies in the noise are then inverted and played into the users ears. The inverted signal then cancels out all ambient noise entering the ears thus eliminates it. In essence the noise cancellation headphones use noise also referred to as “antinoise” to get rid of ambient unwanted noise. This method of reducing unwanted noise is referred to technically as active noise control (ANC).
Noise canceling headphones are typically used in loud environments, the widest use being in planes. Other places of common use include trains, Tube systems as well as in loud offices or work environments with steady background noise like that of air conditioning systems. The reason they work so marvelously is that unlike sound isolation headphones, noise cancelling headphones eliminate deep and continuous noises or hums like that of a jet engine while sound isolation headphones would merely block noise such as people talking.
Using Noise Cancelling Headphones
Noise cancelling headphones have been in use from the 1950s where they were developed mainly for helicopter and plane pilots to help reduce the noise in cockpits. Nowadays however they are commonly available for use for anyone who can purchase them. These headphones are available both as ear-buds for use inside ears and as full size headphones. The better quality ones are usually some of the better over ear headphones but there are some smaller in ear versions that work quite well also. It’s really a matter of choice but for the best noise cancelling you do need to be looking at over ear headphones.
Some of the main merits of noise cancelling headphones are the obvious allowing a person to experience what they are listening to, be it music, watching a film or an audio book or presentation without interference from unwanted noise. Tied to this is noise cancelling headphones are friendly to the ears in the sense of reduction of fatigue to the ears. This is because the volume doesn’t have to be excessively high to counter background noise thus listening is done on lower levels. Noise cancellation can also aid in helping someone sleep in a noisy plane, vehicle or train.
Some main demerits are they are battery powered meaning replacement batteries might be needed in case they run out of power. Without power noise cancelling headphones are rendered useless. Some brands allow a USB port for recharging while some expensive headphones are manufactured in a way that allows usage as normal headphones in case power runs out. Given that the battery compartment is most of the time in built to the headphones, they tend to be bulky unless one opts for the ear-bud versions. The weight of noise cancelling headphones makes them unsuitable for outdoor use and tends to restrict them to travel listening not general day to day use.
Getting Noise Cancelling Headphones
Some of the best reviewed and prominent brands of noise cancelling headphones include Shure SE530 earphones, TMA-1 headphones manufactured by Aiaiai, Klipsch Image S4 and QuietComfort 3s developed by Bose. Prices for noise cancelling headphones range from $40 and can go as high as $500. When shopping for noise cancelling headphones, one needs to consider the design in terms of the size and portability. Full sized headphones are larger and cannot be carried in a pocket while ear-bud headphones will fit the pocket as such how one is traveling needs to be considered when choosing the design. The duration of use is also an important consideration so that a suitable powering means is selected. When selecting noise cancelling headphones for extended periods of use, a lithium-ion rechargeable battery is advised.
