Hearing is a miraculous process.
This is how it works: Your ears receive sound. Then, the sound travels down the ear canal through the middle ear and into the cochlea, where tiny hair cells that reside there vibrate to the different frequencies. Those signals are ushered to the brain, which deciphers the incoming messages and makes sense of them. Your brain automatically filters out the background noise and non-important information to allow you to center on speech and other important signals, when you have normal hearing.
Distinguishing speech from noise is a much greater problem for people with hearing loss. Because the small hair cells in the ear are damaged, there’s trouble separating speech from noise. Also, loud noise can create discomfort for those with hearing loss.
Hearing aids with directionality combat the issue of not being able to separate speech from noise. They have two or more microphones separated by a specific distance on a hearing aid. But not all directional systems are the same. For glossary terms and technical specifics, below are some points about directionality and hearing aids.
Now, here’s an overview of directional systems:
The importance of directionality
Having directional microphones in hearing aids is important because they handle or manage noisy environments well. It’s a solution to better performing hearing aids.
