1. A hearing safety device configured to be worn by a user, the hearing safety device comprising:
an earmuff body, the earmuff body defining:
an interior cavity configured to receive the user's ear therein when worn by the user; and
an exterior surface opposite the interior cavity;
an ear lid attached to a surface of the interior cavity, wherein the ear lid projects into the interior cavity from the surface of the interior cavity, the ear lid defining a sealing surface configured to substantially seal an ear canal of the user's ear when the hearing safety device is worn by the user;
a first sensor operably coupled with the interior cavity and configured to generate first sensor data indicative of a sound intensity within the interior cavity;
a second sensor operably coupled with an exterior environment of the hearing safety device and configured to generate second sensor data indicative of a sound intensity of the exterior environment; and
an adjustment mechanism operably attached to the ear lid and configured to move the ear lid relative to the interior cavity of the earmuff body based on a sound intensity difference, wherein the sound intensity difference is a difference between the sound intensity within the interior cavity and the sound intensity of the exterior environment.
