With the explosion of digital music and videos in recent times and the concurrent proliferation of digital portable players, it is common for listeners to indulge in such entertainment through personal headphones or earphones while they are commuting on public transport, studying or simply window-shopping at the mall. A downside to such an activity is that one cannot escape from the din that permeates through your headphones or earphones. The noise can come from a variety of sources, be it a bus, an airplane engine or the surroundings of a busy shopping centre. Naturally, this can mar one's listening experience.
Fret not, there are ways to reduce or even come close to totally eliminate the noise with specially constructed headphones and earphones. These generally take the form of passively isolating the surrounding noise from your hearing, or using powered circuitry and digital signal processing to cancel out the surrounding noise. How either of these two technologies is incorporated into the headphone or earphone model depends on its intended use, size, and design.
Should you then choose an audio piece with Noise-Cancellation Technology or Noise-Isolation Technology? In well-engineered and well-designed headphones and earphones, both methods of blocking out external noise deliver as promised. Both aim to offer the most pristine music or soundtrack playback without background noise. Some music connoisseur may prefer minimal electronics used for their headphones while others may not be entirely comfortable with an in-ear design that intrudes into their ear canals. It also comes down to the listener's choice in terms of size, portability and style. The Aurvana range offers a selection that caters to your preferences while delivering uncompromised audio performance in each of them.
Let's take a closer look at both of these anti-noise technologies.
