Utah Code Title 34A. Utah Labor Code § 34A-2-504. Hearing loss--Extent of employer's liability

(1) An employer is liable only for the hearing loss of an employee that arises out of and in the course of the employee's employment for that employer.

(2) If previous occupational hearing loss or nonoccupational hearing loss is established by competent evidence, the employer may not be liable for the prior hearing loss so established, whether or not compensation has previously been paid or awarded. The employer is liable only for the difference between the percentage of hearing loss presently established and that percentage of prior hearing loss established by preemployment audiogram or other competent evidence.

(3) The date for compensation for occupational hearing loss shall be determined by the date of direct head injury or the last date when harmful industrial noise contributed substantially in causing the hearing loss.
