Very young children learn words at a tremendous rate. Now researchers at the Center for Mind and Brain at the University of California, Davis, have for the first time seen how specific brain regions activate as two-year-olds remember new words — while the children were sleeping.
Multilingual people have trained their brains to learn languages, making it easier to acquire more new languages after mastering a second or third. In addition to demystifying the seemingly herculean genius of multilinguals, researchers say these results provide some of the first neuroscientific evidence that language skills are additive, a theory known as the cumulative‐enhancement model of language acquisition.
This study revealed that for some individuals with a mild-to-moderate high frequency hearing loss, the use of an amplifier app can result in enhanced listening performance—and even performance within normal limits in background noise. However, the quality of the earphones used does make a difference. These apps and earphones may be particularly useful for these patients who—for whatever reason—could benefit from amplification but are not yet ready for a hearing aid.
According to Starkey’s announcement, members of the executive team spoke at each launch event to over 1,000 customers, partners, and government officials with the help of the dedicated teams in Korea, Japan, and China.

Research has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities.

An alarming 21% of respondents experience tinnitus symptoms such as ringing, buzzing, or persistent noise in the ears. Among these respondents, less than half have seen a doctor or hearing care professional about their symptoms, 25% do not think that they need to, and worryingly, almost 40% are not concerned about their overall hearing health, despite nearly half reporting that they do not have good hearing.

Those who had imagined the sounds without experiencing the shocks decreased their fear responses to the real sounds just as well as those who really heard them without experiencing the shocks.

As yet there is no treatment to stop the tinnitus noise but this research, funded by the British Tinnitus Association (BTA), shows that treatment can make it less severe, intrusive, and bothersome.

The research provides new evidence for how the brain creates perceptual illusions when speech is degraded at cocktail parties, in song lyrics, or for older listeners.

The study reportedly found that, in contrast to existing theory, the more a person’s brain became responsive to lip reading the more it also became responsive to sounds delivered through their CI, and the better they were able to hear.
