There’s a big buzzword going on in the world of the headphone. Noise cancelation! What is it, and do you really need it? How does it work? Read on to find out. It’s really just science, but it’s a kind of magic!
Noise canceling headphones are designed to reduce unwanted ambient sounds using active noise control. This is in contrast to passive noise control, which if used is really just similar to covering your ears so that you hear less sound. The easiest example of passive noise control is the headphones that you would typically wear at a gun firing range; which are designed specifically to dampen sound and make sure you aren’t damaging your ears.
Volkano Silenco Headphones use Active Noise Control technology to achieve a similar effect, but specifically for ambient noise that is repetitive in nature. The key word here is “active” – instead of just trying to block the sound out completely, there are special microphones in the headset that listen to the sound, and produce a sound of their own to cancel out that sound from being heard.
Okay hang on, I hear you. Everything seemed understandable until that last sentence and now you are just confused again. It’s just important to know the difference for now. We will go into more details as we progress.
Active Noise Control technology was first invented in 1936 but used more commonly in the 1950s as a way of helping to make noise from the helicopter and airplane cockpits quieter.
The microphones on an active noise canceling headset are continuously listening to the environment, and capture the steadiest sound frequencies – this could be the noise of an airplane, machinery, a car, or even an air-conditioner. The system then generates a “reverse” frequency and emits a new sound that is inverted to the original sound wave. Together the resulting sound waves cause interference and effectively will cancel out the ambient noise sound that would have gone into your ears.
The result is that you hear less of the primary noise. It only really works well with sounds that are steady and regular, as these sounds are the easier ones to reverse. Irregular sounds, such as voices won’t get canceled, and you will still be able to hear those; but the hum of a noisy office will still be massively reduced.
Remember, noise canceling isn’t the same as passive soundproofing; it simply reduces the noise in certain environments. The best of both worlds is a combination of the two. Ideally, you want an over-the-ear headphone that works as a bit of sound-proofing, as well as the Active Noise Cancelation technology for the best effect.
A comfortable fit is very important, as the better the fit, the better the effect of Active Noise Cancelation is. The Volkano Silenco features ear cups with comfortable padding that swivel, helping to adjust perfectly over your ears for the best effect. These are the features you need from a great set of noise canceling headphones!
Even if you aren’t listening to music over Bluetooth or the aux input, the noise cancelation still works, and as such, it can help with sleeping in those especially noisy environments. Anywhere where you need a bit of peace and quiet, Noise Cancelling Headphones are an ideal option for you.
The Volkano Silenco Active Noise Canceling Headphones offer passive and active noise canceling technology, as well as the added ability to take calls hands-free from a connected device.
