Every single shot can cause irreparable damage to your hearing. It is therefore advisable to wear suitable hearing protection at all times when shooting. Practical considerations when hunting means that this is not always possible. Using moderators has become the new standard, which is hugely advantageous when hunting. The muzzle report and recoil are noticeably reduced. Both play a significant part in achieving better accuracy. The Moderator provides less danger of hearing damage and the pain threshold of 130dB at the ear is rarely reached.
