Sound Filtering Applied to Hearing Aids

Wednesday, February 24th, 2010

Hearing Aids can now filter background noise so the wearer can distinguish voices of friends and loved ones. The technology was originally intended for use in cell phones, but people with healthy hearing found the sound distortions distracting. Scientists then began to develop the software for hearing aids.

They have been using a mathematical model to demonstrate speech recognition. Through this, they are learning how to clear out certain information before it reaches the brain. The technology gets rids of some background noise, and the hearing-impaired can fill in the missing sounds themselves.

Early Auditory Input Helps Children Speak

Wednesday, February 24th, 2010

Children who have early exposure to auditory input have better language skill development, studies show. If children receive treatment for hearing loss before they are 13 months old, their word-learning skills could be more advanced than children who do not receive treatment until later.

Children can then begin distinguishing spoken words and their meanings. This early development can help with speech and word association later in life.

Music Leads to Speech Development

Wednesday, February 24th, 2010

Studies show that early music training shapes the sensory system more than previously understood. Some neuroscientists say that students might process speech in noisy classrooms better if they play an instrument. They say that K-12 music programs should not be the first thing to go in schools that don’t have much money, because it could change the way they learn and pick up sounds in the future.

Researchers have found evidence that music training enhances the brain’s sensitivity to speech sounds. The brain can therefore more fully process the sounds occurring around a person.

Relationship Found Between Neuron Functions

Friday, February 19th, 2010

When barely audible sounds reach the ears, they are amplified in the cochlea before being transmitted to the brain. The tiny hair cells inside the ears, which are actually neurons with tiny sensory hairs, magnify the sound by their motion. Now, new studies show that these hair cells do something similar with information about balance and spacial orientation before sending it to the brain. They respond to a greater magnitude for small motions of the head.

The smaller the sound or movement, the more these tiny hairs jump into action. These cells are limited and can easily be damaged. With the knowledge of this relationship between the two functions of the hairs, scientists can better study how to treat hearing and balance loss.

Brain Found to be Chaotic

Wednesday, February 17th, 2010

It might be a good thing that new research has found the brain’s processing methods to be more chaotic than previously thought. Neighboring cells in the brain can have frequency processes which are dramatically different from each other. Formerly, studies were based on a small sample of available neurons and making inferences on how the rest would respond.

New studies, though, allow scientists to see how a group of neurons interact simultaneously in a larger region of the brain. They have been injecting dye into the brains of mice, and can then see how different neurons respond. This will help the study of how the brain processes sound, and will hopefully lead to more improvements in the treatment of hearing loss.
