Who doesn't like listening to music without the annoying noise of a big city? This has become possible thanks to the advent of active noise cancellation technology in headphones. It remains to be seen how safe it is.
Active Noise Cancelling (ANC) technology has been around in headphones for 35 years. But its widespread use has only begun recently, and only a few years ago it moved from being the preserve of flagship devices to being actively used in mid-range models. Last year, the market was deeply shaken by the emergence of very budget TWS headphones with active noise cancellation.
So it's no surprise that interest in active noise cancellation is greater Bulk SMS Service in Sri Lanka than ever these days. And with the rise in the number of ANC headphone users, the question of how safe this technology is has arisen.
How active noise cancellation works
The principle of active noise cancellation is quite simple. Any sound is first of all a wave. And in order for the wave not to reach the desired point, it must be extinguished with the help of another wave. This is what ANC does.
On the outside of any ANC headphone are sensitive microphones that pick up all external noise. They transmit it to the headphone’s DSP processor, which inverts this noise, and the internal speaker plays the sound received from the DSP. As a result, the two sound waves cancel each other out, and you continue to enjoy your pleasant music.
