Many of us take hearing for granted, but humans are unique in the way we interpret noises from our environment: We can utilize cognitive processes (knowledge, memory and intelligence) with the sensory input we receive. This allows us to communicate, learn and share thoughts and ideas.
Our peripheral and central nervous systems extract and interpret information from multiple, competing sounds in our listening environment, assigning meaning to what might otherwise be considered background clutter. When you have hearing loss, your ability to gauge the meaning of a sound that has been separated from its physical source is compromised, leading to confusion and frustration—proof of the strong correlation between hearing and cognition.
Patients with poor hearing often rely on acquired knowledge to fill in the missing blanks. Those who wear hearing aids utilize cognitive reserves to fill in the blanks when auditory signals are at a minimum. When hearing is compromised, our cognitive system must work harder to interpret sensory input data. It has to increase attention, boost short-term memory and apply previously acquired knowledge to help make sense of the world around us.
Aural rehabilitation can help by training the brain to improve cognition. Providing the best sound quality delivered at the best possible signal-to-noise ratio eases the cognitive burden, improving the ability to hear while reducing the effects of cognitive decline. Amplification features, including directionality, binaural amplification, FM systems and wireless connectivity, contribute to improved sound quality and a lower cognitive burden. In short, the easier it is to listen, the better our ability to hear.
