Discovery of a new set of hearing states in the human ear

According to RCO News Agency, Researchers have shown a new layer of snail complexity using the mathematical models available on a general model of ear snails. These findings provide a new understanding of the significant capacity and accuracy of human hearing.

According to Science Dilly, physicists at Yale University have discovered a complex and unknown collection of “states” in the human ear, which pushes important restrictions on strengthening weak voices, tolerance of noisy explosions, and recognizing the stunning spectrum of sound frequencies in the ear.

Benjamin Machta, an assistant professor of physics at Yale School of Science and Art and a senior professor at the university, says: “We decided to understand how the ear can regulate itself to identify weak sounds.” But to reach the end of this issue, we encountered a new set of low frequency mechanical modes that the snails are likely to support.

In humans, the sound is converted to electrical signals in the cochlea. Humans are able to detect voices with frequencies at three times large and more than one trillion times the power to small air vibrations.

When the sound waves enter the snail, they become surface waves that move along the base of the cochlea’s hair.

Every pure tone sounds at one point along this spiral organs. Hair cells at that place tell your brain what sound you hear.

These hair do something else. They act as mechanical amplifiers and pump energy into sound waves to cope with friction and help them reach their destination. According to the researchers, pumping the right amount of energy and constant adjustments is very important for accurate hearing.

But these are a collection of well -documented auditory modes that have been well -documented, and Yale has discovered the second and extensive set of these in the snail.

In these developed modes, a large part of the basic membrane reacts and even moves together for one tone. This collective response creates restrictions on how hair cells react to the input sound and how the energy cells were pumped to the base membrane.

Since these newly discovered modes show the low frequency, the researchers believe their findings may also help better understand low -frequency hearing, which is still an active research field.
