In ear noise-cancelling headphones

Noise canceling headphones reduce unwanted ambient noise with the help of active noise control. This differs from passive headphones that, if they attenuate ambient noise, use techniques such as noise isolation.

The information about a Noise canceling headphones shows the amount of noise they can cancel in terms of decibels. This number can be useful for comparing products but it does not tell the whole story as it does not indicate the noise reduction at different frequencies.

Noise cancelling

Noise cancellation makes it possible to listen to music in a noisy environment without increasing the volume excessively. To mask the lower frequency parts of the ambient sound, the headphones have a microphone that analyzes the sound, filters the “noise” out of the music and then produces the music while attenuating the low frequencies. If those low frequencies belong to the music, they are also muted.

The music is not affected by digital masks

To prevent a higher frequency from reaching the ear, most noise canceling headphones rely on sound isolation. This is done by completely enclosing the ear with the cushions of the headphones. Higher frequencies have a shorter wavelength and dampening this noise requires complicated algorithms that compromise the quality of the sound. In order to project these short sound waves onto the eardrum without damaging volume, it is necessary to place the speaker close to the eardrum. This is only possible with an in-ear headphone. With a custom made in-ear headphone, natural isolation is used to reduce unwanted noise as much as possible. The music is unaffected by digital masks and is played as output from the source.
