How do noise canceling hearing aids work?
This feature is especially useful for those who commute regularly, suffer from noise sensitivities, and hearing loss who work in noisy environments. This technology is easily accessible, but you might be curious about how it works.
These adjustments are made in different frequency bands, improving comfort without compromising intelligibility by reducing noise-dominant frequency bands while preserving those useful and important for speech understanding.
For example, the noise is mostly in the low frequency band, while the voice is in the middle and high frequency, the noise reduction system will reduce the gain of the low frequency band, and will not deal with the sound of the high frequency band. To achieve the purpose of “filtering noise”. Most of the current mainstream hearing aids are multichannel, and the noise reduction function can work independently in each individual channel.
