Noise Cancellation Noise cancellation is a relatively new feature that can be found in some models. Basically, what they generate are sound waves that collide with the waves coming from outside and have the effect of significantly attenuating the noise generated around them so that the listener can concentrate exclusively on the music. This technology is good for DJs or listening to music in very noisy environments. In some designs, it is possible to activate or deactivate this function. Almost all of these models are currently powered by batteries to operate the noise cancellation. Frequency This is the range of sounds that the headphones can deploy. It is measured in hertz and includes everything from the highest frequencies to the deepest bass. Normally, there is a range compatible with each model, for example, 18 Hz to 30,000 Hz. The larger the range, the better, as this achieves greater sensitivity in bass and treble. As a reference, humans can hear frequencies between 20 Hz and 20,000 Hz.
