The advantages and disadvantages of noise-cancelling headphones ?
The noise-cancelling headphones are the headphones that reduce the unwanted ambient sounds using the active noise control engineering , Noise cancellation makes it possible to enjoy the music without raising the volume excessively , It can also help a passenger sleep in a noisy vehicle such as an airliner .
In the aviation environment , The noise-cancelling headphones increase the signal-to-noise ratio more than the passive noise attenuating headphones or no headphones , making hearing important information such as the safety announcements easier , They can improve listening enough to completely offset the effect of a distracting concurrent activity .
The noise-cancelling headphones use active noise control to cancel the lower frequency portions of the noise , They depend on more traditional methods such as the soundproofing to prevent higher frequency noise from reaching the ear .
Noise-cancelling headphones advantages
The noise-cancelling headphones provide excellent hearing protection against the constant levels of noise , You get much greater noise attenuation , The noise reduction works on all external noise , not just low-frequency continuous droning sound .
The nice thing about the noise-cancelling headphones is that much of the external sound is blocked without having to replace it with even louder sounds , The volume level on the music can be turned down to a more enjoyable and comfortable level and still be heard over loud noises produced by the surrounding environment , This is good news for people wishing to preserve their ear health .
The noise-cancelling headphones are useful for travelling especially for the people who travel on commuter trains or airplanes , They need to block out the outside noise during these times in order to sleep , read , study or work .
Using the noise deleting ear sets will block the outside noises and will prevent them from disturbing the wearers , The headphones will help them focus on several tasks much easier .
The headset allows you talk more comfortable on the phone , and if the wireless also offers you the flexibility to move about your home or the office whilst you speak ( with most wireless headsets providing a range of up to 150m ) .
The music volume does not need to be high , The people have been turning up the volume on their music to extreme levels , because they actually prefer it at that level , Many listeners only crank up the volume in an effort to drown out the external world and listen to the music in peace .
The noise-cancelling headphones allow the users to turn the volume down and hear the intended richness and the variations in the music that disappear when the volume is pushed to the limits .
Many students find it hard to concentrate especially when the sounds are distracting them at all times , Using the noise-cancelling headphones helps the students to block out the external world and concentrate on what they need to learn .
Noise-cancelling headphones disadvantages
The noise-cancelling headphones are more complex , and therefore they are often more expensive than the standard headphones due to additional costs in the manufacturing of noise-cancelling technology .
The noise-cancelling circuitry required for them to operate may reduce the audio quality and introduce some high-frequency hiss , This limitation may be offset by reductions in the external noises that would otherwise reduce the audio quality .
They can be bulkier and heavier than the standard headphones to incorporate batteries and additional electronics needed to provide noise-cancelling , The noise-cancelling headphones are not suited for environments where sudden loud noises are present such as the large rocks falling or gunshots .
The biggest disadvantage of noise-cancelling headphones is the relative cost difference between noise-cancelling headphones and their alternatives , A decent set of regular headphones can be purchased for a reasonable price , and their design and volume levels can help the user drown out the majority of outside sounds , A set of noise-cancelling headphones costs around 10 times as much as these alternative sets .
The internal components of a set of noise-cancelling headphones use a considerable amount of power , Some of the sets get this power from internal batteries and some of those are rechargeable , These sets are generally a bit heavier than the headphones that do not carry their own power supply .
Some people complain about hearing the humming sound when wearing them , The sound which is actually barely perceivable also causes some people to feel pressure on their eardrum when wearing them , Those who are sensitive to this may want to limit their use , at least until they adjust to it .
