Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather than a power source. Active noise canceling is best suited for low frequencies. For higher frequencies, the spacing requirements for free space and zone of silence techniques become prohibitive.
Simplified graphical depiction of active noise reduction. To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control or ANC.A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds.
These headphones also deliver modern noise-canceling features, including adjustable levels of sound blocking and a monitor mode that pipes in outside sound when you want to hear it.
Noise-cancelling headphones and sound-isolating earphones can help one avoid turning the volume up to overcome loud background noise. Sound measurement apps can help one find out how loud sounds are. If not measuring the sound levels, a good rule of thumb is that sounds are potentially hazardous if it is necessary to speak in a raised voice to ...
