With the hustle and bustle of everyday life, we often need a bit of peace and quiet. Our lives can be very stressful; from balancing work and social life, to loved ones and personal hobbies, to finding a way to prioritize our health, sometimes we need a little break from the chaos which is (or can be) life. One method of disconnecting from the rest of the world is to use noise-canceling headphones. As a relatively new and revolutionary technology, noise canceling headphones reduce unwanted ambient sounds using noise control technologies. Whether you’re an audiophile, music lover, podcast listener, or just love the comfort of being in your own world,
Did you know that there are actually different types of noise reduction? While many are already familiar with ANC (active noise cancellation) as well as the lesser known passive noise cancellation (PNC), another type of noise cancellation technology to be aware of is called digital noise cancellation (or DNC). These three types of technologies all reduce unwanted ambient sound, but there are several distinctions between them that are important to consider when finding the perfect pair of noise canceling headphones for you.
The best known and most popular type of noise canceling technology is active noise cancellation. ANC technology consists of microphones that “listen” for noise both inside and outside the earphone or headset, working alongside an ANC processing circuit that reverses the phase of the sound waves , and the earphone or headphone speakers generate the phase-reversed sound waves by the circuits. to cancel outside noise. The two sound waves virtually cancel each other out when they collide with another sound wave of the same frequency but opposite amplitude. This is equivalent to adding +1 and -1 to get zero.
ANC is a great choice for frequent travelers because the active noise-canceling feature is more effective at reducing low, persistent sounds, such as an irritating roar from the air conditioner or other unpleasant sounds generated by engines, subways and aircraft engines. However, if your goal is to filter out crying children or barking dogs, perhaps opt for passive noise cancellation technology instead.
On the other hand, passive noise cancellation does not rely on any electrical components. Instead, it depends on the actual characteristics of the headphones or headphones to physically filter out unwanted sounds. This is often accomplished by using thick padding applied or ear tips on the headset or earphones, which reduce outside noise. It can be quite effective at blocking out outside noise, especially in the higher frequency range, and this type of noise cancellation is frequently found in less expensive headphones and earbuds.
PNC headphones require a snug, custom fit tailored to your specific ear shape, which can make your listening experience more comfortable. In order to block out unwanted noise, whether it’s mid- or high-frequency noise, PNC headphones use well-designed ear cups and earpads. PNC technology in your headphones or headphones blocks ambient noise from entering your ear canal by molding them precisely to the shape of your ears, so your ears are physically separated from the noises you don’t want to hear through passive cancellation noise. As a result, you can listen to music at lower volumes because you don’t have to counter sounds from your surroundings as much as you would with ANC.
Digital noise cancellation (often called digital noise cancellation or DNC) uses a technology called digital signal processing (DSP) to remove unwanted noise. It works by evaluating the incoming audio signal and then creating an “antiphase” of the noise, which is then removed from the original audio signal. This type of noise cancellation is often found in high-end headphones and earbuds. As a result, the audio experience is noticeably cleaner, crisper and has less background noise. DNC works by capturing background noise and adding anti-phase noise that cancels out sounds like the roar of a mighty V8 engine, the hum of an airplane engine, or even the background noise of a busy city street. city.
DNC earphones feature the most precise and accurate noise cancellation technology on the market. It is perhaps the most effective technology for reducing unwanted background noise, although it can be quite expensive. Using both exterior (feed forward) and interior (feedback) microphones for superior noise cancellation technology, it helps to enjoy clear audio quality like no other without being disturbed by ambient noise.
Ultimately, whether you’re flying at 30,000 feet, taking the subway, or walking down a noisy street, you’ll want your home audio or entertainment experience to be seamless, crisp, and enjoyable. Noise cancellation can eliminate almost unwanted buzzing sounds, so it’s important that you choose the one that’s right for you. Each type of noise canceling technology has its own advantages and disadvantages. Your personal taste, budget, and the type of noise you want to block out will determine which type of noise canceling technology is right for you.
Being surrounded by so much background noise makes it difficult to listen to music while navigating the environmental chaos of everyday life. These types of noise reduction technologies are great at reducing the noise around you, so whichever type you choose will significantly reduce ambient noise, while providing a comfortable listening experience and great sound quality. Phiaton strives to deliver innovative technologies for its audio products that combine unparalleled sound quality with modern design for today’s hectic lifestyles, so take your pick and quell the hustle and bustle of everyday life with a pair of your own noise canceling headphones.
