Abstract
An ear insert for protecting the ear from loud noise can have a stem that is configured to be inserted into an ear canal. One or more attachments can be configured to attach to the stem in a manner that at least partially defines a fit of the ear insert within an ear canal. For example, rubber o-rings can be can be selected according to their size so as to provide a desirable fit of the insert within the ear canal. In this manner, the undesirable leakage of ambient noise into the ear canal is mitigated and hearing protection is enhanced.
