A recent study has provided evidence that the Ponto(BAHS) sound processing allows wearers to learn faster, remember more, and use less listening effort. In this post, we’re going to focus on the benefits of remembering more.
Evidence indicates Oticon Medical BAHS support memory
First, a review of the study and its results with regards to memory: Professor Thomas Lunner and Oticon Medical partnered to assess how the Ponto system might support memory function. 16 adults in their late fifties with conductive or mixed hearing loss were tested while wearing two Pontos: one optimally fitted on softband and one on abutment. The subjects were tested with one Ponto at the time, in random order. After listening to seven sentences, they were asked to recall as many last words of the sentences as possible The subjects could remember 46 percent of the last words with the Ponto fitted on softband. However, when they wore Ponto attached to their abutments, they remembered 52 percent of the words correct. This means wearers experienced a 13 percent relative improvement in ability to remember words with direct sound transmission versus skin transmission.
The impact of hearing loss on memory
A separate study found that 56 percent of participants evaluated for memory and cognitive concerns, as well as potential brain disorders like dementia or Alzheimer’s disease, had some form of hearing loss ranging from mild to severe, and about 36 percent of them had not received treatment for their hearing loss. Additional studies have concluded that untreated hearing loss is a significant risk factor in the development of memory and thinking disorders . However, it’s also a contributor that you can affect by treating your hearing difficulties – and the sooner, the better.
What it all means to you
Researchers have multiple theories as to why hearing affects memory, including that when fewer mental resources are needed to process incoming sound signals, more can be devoted to remembering. Also, when you can hear better, you’re likelier to continue actively engaging in social situations like going out to restaurants with friends or attending family gatherings. Regular social interaction stimulates your brain and supports emotional health, both of which are vital to preventing isolation and depression – both of which are known contributors to the development of dementia or Alzheimer’s disease.
Evidence strongly indicates that a Ponto system offers wearers more than the ability to hear better. When worn implanted on an abutment, these powerful BAHS can significantly improve your ability to remember.
