Hearing loss could be prevented by an injection dubbed 'chemical earmuffs' by scientists.
Biologists say they have discovered a way to preventing the damage caused by loud noises while not muffling the sound.
Funded by the US Department of Defence, the successful testing gives hope soldiers will one day be able to take a hearing-protection drug before being exposed to gunshots.
The drug, being designed by researchers at the University of Iowa and Washington University in St Louis, would protect auditory receptors while allowing soldiers to still hear commands and one another.
Tinnitus and hearing loss are the top causes of disability for US veterans. A new drug tested in mice may prevent damage to auditory neurons without preventing soldiers from hearing
They discovered a drug that blocks a receptor that prevents the breakdown of vital auditory synapses.
A receptor are part of a molecules in ear nerve cells that bridge the pattern of sound and auditory information from sound sensors to the brain.
The successful transmission of sound occurs through a junction called a synapse.
The researchers identified some receptors lack a protein called GluA2, and it is these lacking receptors that are responsible for hearing loss.
When biologists blocked the faulty receptors in mice, it prevented them from sustaining hearing damage.
Professor Steven Green said: 'Now, we
