A new study found that nerve damage to the inner ear is associated with endolymphatic dropsy, a buildup of fluid in the inner ear. Fortunately, scientists have seen that saline treatment of the ear reduces nerve damage.
The researchers studied how the ear is affected by normal loud sounds in the range of 80 to 100 decibels. They measured the fluid level in the inner ear. It turned out that before the sound was 95 decibels, the fluid level remained normal. But after exposure to 100 decibels – which is equivalent to the noise from a lawn mower or motorcycle – fluid accumulated.
It is worth noting that this study was conducted in mice.
