3M Earplug Lawsuit: Veterans’ Hearing Loss Case Study

Executive Summary

This case study focuses on the journey of Mr. J, an Army veteran who sustained chronic hearing difficulties alongside tinnitus because of using 3M Combat Arms Earplugs (CAEv2) that were issued to him during his service. His hearing issues began well after his service, which prompts the question of why he started battling them. Throughout his service, CAEv2’s earplugs were an integral part of his life due to the condition he suffered from, tinnitus.
