Baby boomers, listen up.

A convention being held in Los Angeles is offering high hopes for the hard-of-hearing with new devices to help people hear better amid predictions that more and more Americans - including baby boomers - are going to need them."The level of hearing impaired people in the United States is projected to grow," Jerry Ruzicka, president of Starkey Labs, said at the 10th annual convention of the American Academy of Audiology, which is being held through Sunday.

"The baby boomers, throughout their lives, have been subjected to higher levels of noise than previous generations, so we expect to see (an) increase in hearing impairment," he added.

As a result of the expected demand, numerous high-tech devices are being introduced.

For example, there's a revolutionary new hearing aid that promises the hard-of-hearing three-dimensional sound.

Another new product does away with hearing aids altogether - thanks to a device implanted in a person's skull.
