The Science of

Silence: Understanding Active Noise Cancelling

At its core, active noise cancellation is a sophisticated dance of sound waves.

Tiny microphones in the headphones capture ambient noise, and the built-in electronics generate an "anti-noise" signal of the same frequency but in the opposite phase, effectively canceling the unwanted sounds. The better the headphones can perform this delicate operation, the more successful the noise cancellation will be.

Sounding Good while Keeping it Quiet

One might wonder if it's feasible to achieve high-quality sound while simultaneously canceling out ambient noise. The answer is a resounding yes, with the caveat that it largely depends on the specific model and brand. Not all ANC headphones are created equal, and the quality of the sound they produce can be affected by the effectiveness of their noise cancellation.

Take, for example, the QC45 ANC headphones. These Bose QuietComfort 45 Bluetooth Wireless Noise Cancelling headphones have been lauded for their exceptional noise cancellation, backed by Bose's proprietary acoustic technology.

It employs an architecture known as TriPort, offering depth and fullness to the audio, while a volume-optimized Active EQ ensures consistent bass and clear music at all volumes. Such features ensure an immersive, highfidelity sound experience even as ambient noise is pushed to the background.
