What goes inside Brains of Older Adults? Why they Struggle to Hear in Noisy Places?

For older listeners, even when there isn't any noise, the brain is already having trouble processing the speech

New York, October 19, 2016: Something must be going on in the brains of older adults that causes them to struggle to follow speech amid background noise, even when their hearing would be considered normal, researchers from University of Maryland have determined.

Researchers Samira Anderson, Jonathan Z Simon and Alessandro Presacco found that adults aged 61-73 with normal hearing scored significantly worse on speech understanding in noisy environments than adults aged 18-30 with normal hearing.

The researchers studied two areas of the brain. They looked at the more ‘ancestral’ midbrain area which does basic processing of all sounds.

They also looked at the cortex which is particularly large in humans and part of which specialises in speech processing.

In the young group, the mid-brain generated a signal that matched its task in each case – looking like speech in the quiet environment, and speech clearly discernable against a noisy background in the noise environment.

But in the older group, the quality of the response to the speech signal was degraded even when in the quiet environment, and the response was even worse in the noisy environment.

“For older listeners, even when there isn’t any noise, the brain is already having trouble processing the speech,” said Simon.

Neural signals recorded from cortex showed that younger adults could process speech well in a relatively short amount of time.

But the auditory cortex of older test subjects took longer to represent the same amount of information.

“Part of the comprehension problems experienced by older adults in both quiet and noise conditions could be linked to age-related imbalance between excitatory and inhibitory neural processes in the brain,” Mr Presacco added.

This imbalance could impair the brain’s ability to correctly process auditory stimuli and could be the main cause of the abnormally high cortical response observed in the study.

“Older people need more time to figure out what a speaker is saying. They are dedicating more of their resources and exerting more effort than younger adults when they are listening to speech,” Mr Simon noted in a paper published by the Journal of Neurophysiology.

This eroding of brain function appears to be typical for older adults and a natural part of the ageing process.

The researchers are now looking into whether brain training techniques may be able to help older adults improve their speech comprehension. (IANS)

June 17, 2018:

Restaurateurs Prodyut and Sumana Mukherjee have not only brought Indian cuisine to the ongoing FIFA World Cup 2018 here but also plan to dish out free dinner to countrymen if Argentina wins the trophy on July 15.

Based in Moscow for the last 27 years, Prodyut and Sumana run two Indian eateries, “Talk Of The Town” and “Fusion Plaza”.

Both restaurants serve popular Indian dishes like butter chicken, kebabs and a varied vegetarian spread.

During the ongoing FIFA World Cup 2018, there will be 25 per cent discount for those who will possess a Fan ID (required to watch World Cup games).

There will also be gifts and contests on offers during matches in both the restaurants to celebrate the event.

The Mukherjees, hailing from Kolkata, are die-hard fans of Argentina. Despite Albiceleste drawing 1-1 with Iceland in their group opener with Lionel Messi failing to sparkle, they believe Jorge Sampaoli’s team can go the distance.

“I am an Argentina fan. I have booked tickets for a quarterfinal match, a semifinal and of course the final. If Argentina goes on to lift

“We have been waiting for this World Cup. Indians come in large numbers during the World Cup and we wanted these eateries to be a melting point,” he added.

According to Cutting Edge Events, FIFA’s official sales agency in India for the 2018 World Cup, India is amongst the top 10 countries in terms of number of match tickets bought.

Prodyut came to Moscow to study engineering and later started working for a pharmaceutical company here before trying his hand in business. Besides running the two restaurants with the help of his wife, he was into the distribution of pharmaceutical products.

“After Russia won the first match of the World Cup, the footfall has gone up considerably. The Indians are also flooding in after the 6-9 p.m. game. That is the time both my restaurants remain full,” Prodyut said.

There are also plans to rope in registered fan clubs of Latin American countries, who will throng the restaurants during matches and then follow it up with after-game parties till the wee hours.

“I did get in touch with some of the fan clubs I had prior idea about. They agreed to come over and celebrate the games at our joints. Those will be gala nights when both eateries will remain open all night for them to enjoy,” Prodyut said.

Watching the World Cup is a dream come true for the couple, Sumana said.

“We want to make the Indians who have come here to witness the spectacle and feel at home too. We always extend a helping hand and since we are from West Bengal, we make special dishes for those who come from Bengal,” she added. (IANS)
