Why Loss of Hearing Takes Place After Exposure To Loud Sounds? - Study Finds Reason

A recent study has discovered the reason behind the hearing loss after we listen to hear loud noises or sound. The study published in the journal ‘Proceedings of the National Academy of Sciences’ explains the science behind our ears feeling numb and losing the sense of hearing temporarily.

“Most individuals have experienced that their hearing is impaired and therefore the ear feels numb once being attentive to loud sounds. Once a short time hearing returns to traditional. We've discovered that a little structure within the cochlea known as the tectorial membrane plays a very important role during this method, by acting as a storage depot for calcium ions. These calcium ions contribute to control the function of the sensory cells”, aforesaid lead study author Anders Fridberger.

Calcium ions, which are calcium atoms with a positive charge, play a key role within the processes that make hearing possible. The conversion of sound waves to nerve impulses takes place within the sensory receptor, additionally called the cochlea, which sounds like the spiral shell that some snails have. The cochlea contains several sensory cells, which detect sounds and generate signals that are passed on to the brain.

Previous analysis has shown that the fluid that surrounds the sensory cells within the cochlea features has a low concentration of calcium ions. There were, however, queries encompassing this, because of sensory cells that are placed in fluids with the natural level of calcium no longer work unremarkably.

When the scientists added a substance that mops up calcium ions, the sensory cells ceased to perform. within the next step, they exposed the sensory receptor to noise levels that correspond to those experienced at rock concerts, which had the same effect. The analysis cluster is currently progressing to investigate whether or not a similar mechanism is very important in age-related disablement.
