Jimmy Holifield ("Employee") has been working for the Mississippi Lime Company ("Employer") since 1984. As a result of his employment, Employee has alleged that he suffered tinnitus due to occupational exposure of loud noise. In support of his position, Employee offered the opinions of an audiologist, David Mason, Ph.D. that the prevailing factor of his tinnitus was the noise exposure at his employment with Employer (Employee's Exhibit 4). Employer-Insurer has offered the opinion of Dr. Anthony Mikulec that Employee's tinnitus was not related his work for Employer. It is important to note that nothing in Chapter 287 of the Revised Missouri Statutes or in Title 8 of the Missouri Code of State Regulations requires the opinions concerning tinnitus to be verified by an expert rather than an audiologist or medical doctor. Accordingly, Employer-Insurer's objections are overruled.
At the time of the hearing, Employee testified that during his employment with Employer he worked in very loud areas. On June 30, 2004, Employee reported that he "began experiencing mild, bilateral, constant, tonal tinnitus of unknown etiology about one year ago" (EmployerInsurer's Exhibit E). On July 25, 2005, Employee reported "bilateral intermittent tinnitus which has existed since 1979 (Employer-Insurer's Exhibit C). Although Employee's first indication of tinnitus occurred in approximately 1979, the records indicate that it became constant around 2003. Due to this constant tinnitus, Employee testified that it bothers him on a daily basis which makes it hard to understand kids, communicate with wife, and interferes with other activities. In accordance with 287.063.2 RSMo., "the employer liable for the compensation in this section provided shall be the employer in whose employment the employee was last exposed to the hazard of the occupational disease prior to evidence of disability, regardless of the length of time of such last exposure, subject to the notice provision of section 287.420 ". As a result, I find that Employer was the last to expose Employee to the hazard of the occupational disease prior to the evidence of disability.
Based on the evidence submitted at trial, I find the testimony of Employee to be credible and further find that Employer-Insurer failed to offer sufficient credible evidence to discredit the testimony of Employee. Consequently, I find the opinions of David Mason, Ph.D. to be more credible than the opinions of Dr. Anthony Mikulec in this matter since he fully considers all the limitations and information provided by Employee.
Consequently, I find that Employee has satisfied his burden of proof on the issues of occupational disease and medical causation for tinnitus. I therefore find that Employee has sustained an occupational disease on or about June 1, 2014, arising out of and in the course of his employment and that his employment was the prevailing factor in causing the resulting medical condition and disability.
