Online Training Enhances Communication Skills for Older Adults in Noisy Settings

Recent research indicates that online training designed to help individuals recognize and comprehend new voices could significantly aid older adults in enhancing their communication abilities in noisy environments. This study, conducted by experts at University College London, offers promising insights into improving everyday interactions for seniors.

The investigation, published in the Journal of Experimental Psychology: Applied, explored the effectiveness of trained voices compared to unfamiliar ones among two groups: older participants aged 55 to 73 and younger participants aged 18 to 34. The study involved preparatory online training sessions where participants listened to three new voices, each articulating ten meaningful sentences until familiarity was established.

Following the training, participants were tasked with identifying a specific sentence spoken by one of the familiar voices while simultaneously hearing two unfamiliar voices, simulating a real-life social scenario. Each participant engaged in this exercise 468 times, with the target familiar voice changing throughout the trials.

The results showed a remarkable 30% improvement in the ability to comprehend sentences from newly familiarized voices for both older and younger adults. The lead researcher emphasized that many individuals struggle to understand speech amidst background noise, a challenge that tends to increase with age. Familiar voices, such as those of family members or friends, are typically easier to understand in such settings.

The findings suggest that training designed to recognize newly familiarized voices can yield comparable benefits to those experienced with naturally familiar voices. Participants completed the training from their homes, with effective outcomes observed in less than an hour.

The research team believes that regular practice in recognizing voices encountered in daily life could substantially improve communication for older adults. This form of training may prove especially beneficial as age-related difficulties in understanding speech in noisy environments become more pronounced.

Future plans include personalizing the training to incorporate voices that participants frequently encounter in their daily interactions. The researchers aspire to develop this training into a publicly accessible smartphone application after further technical advancements.

Additionally, the team aims to investigate how this training could assist individuals with hearing loss, a group often facing challenges in noisy environments.

In a related study published in Scientific Reports, the researchers examined how individuals focus on specific voices in crowded settings. They found that both younger adults and older adults with strong hearing capabilities utilize the location of a voice to discern speech. However, this ability tends to decline with age-related hearing loss, even when the hearing loss does not reach a clinically diagnosed level. This suggests that both peripheral and central auditory processes begin to change prior to clinical indicators of hearing loss, explaining the difficulties experienced by those with hearing impairments in noisy contexts.
