They discovered that hours after mice are uncovered to loud noise, their internal ear zinc degree will increase which in the end results in mobile injury and disrupts regular cell-to-cell communication.
Fortuitously, mice that have been handled with a slow-release compound that trapped extra free zinc have been much less vulnerable to listening to loss and have been protected against noise-induced injury.
