Employee's date of birth is August 21, 1958. He was 55 years of age as of the date of the hearing before the administrative law judge. Employee began working for employer on August 8, 1977. Employee worked full-time on employer's assembly line.
When employee began working for employer, he did not have any problems with his hearing. Employee's daily work for employer exposed him to numerous machines, tools, and processes that produced loud noises. Employer provided earplugs, but these were impractical and even unsafe to use, as they hindered the ability of employees to communicate with one another on the busy factory floor.
As part of an agreement between employer and the union to which employee belonged, employee submitted to annual hearing tests at employer's facility. Those tests were performed by doctors employed by employer. As early as 1996, those tests revealed that employee was suffering hearing loss accompanied by severe ringing in his ears. Employer's doctors told employee that his hearing problems and the ringing in his ears were the effects of aging, and advised him to see his personal physician for treatment. Employer's doctors never suggested to employee there was a possibility his hearing problems were connected to noisy working conditions with employer.
Employee took advantage of an early retirement program, and his last day of work for employer was September 3, 2006. Employee's hearing problems and the ringing in his ears continued after September 3, 2006, although they did not worsen after that date. On March 4, 2010, employee saw Dr. Gregory Mulcahy for complaints of hearing loss and ringing in his ears. Dr. Mulcahy told employee that these problems had been caused by his exposure to loud noises during the course of his work for employer.
There is no indication on this record that employee is a doctor, or an audiologist, or that he is otherwise versed in the scientific literature regarding the potential causes of the medical conditions of hearing loss or tinnitus. Especially when we consider that employer's doctors continually assured employee that his hearing loss and the ringing in his ears were merely the effects of aging, we are persuaded (and we so find) that it was not apparent or reasonably discoverable to employee that he'd suffered a work-related injury in the form of hearing loss or tinnitus until his March 4, 2010, visit with Dr. Mulcahy. On March 18, 2010, employee filed a claim for compensation alleging he suffered hearing loss and tinnitus as a result of exposure to occupational noise in the course of his work for employer.
Employee suffers from a continuous buzzing or ringing sound in his ears, which he describes as akin to the sound of locusts. This sensation makes it difficult for employee to concentrate, causes irritation and frustration, and affects his sleep. Employee presented an expert medical opinion from Dr. Peter Bieri, who opined that employee's 30 years of exposure to noisy work with employer is the prevailing factor causing him to suffer hearing loss and tinnitus. Dr. Bieri rated employee's disability referable to tinnitus at 15 % permanent partial disability of the body as a whole.
With regard to the question of future medical care, Dr. Bieri opined that employee's tinnitus is irreversible and will not improve. Dr. Bieri acknowledged the existence of
