Brain Controlled Hearing is Possible Now: Scientists to Come up With Modified Hearing Aid

Rejoice!
Scientists are devising hearing aid devices that will automatically refine desirable voices in multi-talker environment. It will further improve the sound quality by decoding them through brainwaves.

How is the hearing aid different?

People with hearing impairment find it hard to deal with the day to day chores.  It really feels perplexing to distinguish between wanted notes and speakers of a crowded environment.

However, a small experiment has suggested that hearing devices with brain assistance will detect a wanted speech among noises.

The devices shall separate individual available voices, and decode them in accordance to attention payed by the user through brainwaves. The problem is also inclusive of people having normal hearing. It becomes tiring to focus so much upon distinct voices.

Typically, a normal hearing aid can only amplify sounds present in the environment. It becomes challenging to separate the sounds and amplify the required ones.

We call it as auditory attention decoding. The research also focuses upon creating channels of familiar voices including family members, friends and colleagues. The aid will amplify their sound signals extensively.

Follow-ups to the research work

The researchers have proposed an algorithm where seperation of unfamiliar chatters will be done in a multi-speaker situation. It will involve the comparisons of audio patterns through spectrogram.

They carried out the same test on three epilepsy patients. The volunteers had normal hearing and were already heading for surgeries to maintain neural activities of their brains. The patients were made to listen both single and multi talkers of the room.

During multi-talking of speakers, they focused on only one speaker.
The discovered that user’s brainwave responses somehow fit with spectrogram stories.

The existing challenge is to decode these brainwaves without using invasive devices like spectrogram. They are more keen on adding electrodes around or inside the ear of people for better results.

New hardware hearing aid devices has led us to live a healthy, prolonged life. We can hope for our futures to be safe with such wearable devices.
