OPPO Enco Q1 and How Does Active Noise-Cancelling Work?

Noise-Cancelling
Does the prospect of complete immersion in an audio experience, free of distractions, excite you? Most of us are familiar with the concept of noise-cancelling, but how active noise-cancelling works is not especially intuitive. Headphones were originally equipped with noise-cancelling properties in order to counteract undesirable ambient sounds. All models of headphones provide some degree of passive ambient sound reduction, but the reduction level is reliant on material type and can only effectively block out high-frequency sound waves. Active noise-cancelling headphones, on the other hand, are designed to block out both high and low-frequency sound waves.

Destructive Interference
The key difference between passive and active noise-cancelling lies in destructive interference. Active noise-cancelling systems are designed to detect and then cancel out incoming ambient noise. The incoming sound waves are registered by the system’s microphone, which then prompts the speaker to produce sound waves that are both equal and opposite of the incoming sound waves. The noise-cancelling system replicates the amplitude and frequency of the incoming ambient noise, but with compressions and rarefactions arranged in the opposite pattern of the ambient noise – producing a noise-cancelling effect that sounds like silence to the listener. In conclusion, the noise-cancelling system sends out sound waves to interfere with and “destroy” the incoming ambient sounds. The result – the listener can focus on the audio he or she wants to hear.

Noise-Cancelling System
For your device to effectively cancel out incoming noise, the system needs to be equipped with noise-cancelling circuitry, a microphone, a speaker, and a battery. The microphone detects the incoming sound waves, which is then received by the noise-cancelling circuitry which takes note of the frequency and amplitude of incoming waves. The circuitry then creates the new wave which is produced into the headphone speaker. Of course, this also requires battery power from the audio device in order to produce the noise-cancelling effect. Active noise-cancelling results in an additional 20 decibels of noise reduction, which equates to about 70 percent of ambient noise blocked. Noise-cancelling headphones are particularly useful in crowded spaces such as offices, planes, and trains.

OPPO Enco Q1
The Enco Q1 is meticulously designed for daily use and active lifestyles, allowing you to conveniently access your audio any time and place you need it. Featuring Hybrid Active Noise-Cancelling and 3 Immersive Audio Modes, Enco Q1 is perfectly paired alongside the OPPO Reno2. Enco Q1’s innovative hybrid active noise-cancelling system combines both feed-forward and feedback microphones in order to maximize the range of frequencies reduced, resulting in greater noise reduction. Music Mode, Cinema Mode, and Game Mode are each precisely calibrated to best suit the respective media form. With Music Mode’s emphasis on a powerful musical immersion, Cinema Mode’s bass surround sound and 3D effects, and Game Mode’s enhanced in-game acoustic positioning effects, you can trust in your Enco Q1 for exceptional audio in any situation.
