9 both ears that exceeds an average hearing level of
10 twenty-five decibels for the frequencies five hundred,
11 one thousand, two thousand, and three thousand, and
12 four thousand Hertz, arising out of and in the course
13 of employment caused by excessive noise exposure.
14 "Occupational hearing loss" does not include loss of
15 hearing attributable to age or any other condition or
16 exposure not arising out of and in the course of
17 employment.
18 Sec. . Section 85B.9, subsection 3, Code 2001,
19 is amended to read as follows:
20 3. In calculating the total amount of hearing
21 loss, the hearing levels at each of the four five
22 frequencies, five hundred, one thousand, two thousand,
23 and three thousand, and four thousand Hertz, shall be
24 added together and divided by four five to determine
25 the average decibel hearing level for each ear. If
26 the resulting average decibel hearing level in either
27 ear is twenty-five decibels or less, the percentage
28 hearing loss for that ear shall be zero. For each
29 resulting average decibel hearing level exceeding
30 twenty-five decibels, an allowance of one and one-half
31 percent shall be made up to the maximum of one hundred
32 percent which is reached at an average decibel hearing
33 level of ninety-two decibels. In determining the
34 total binaural percentage hearing loss, the percentage
35 hearing loss for the ear with better hearing shall be
36 multiplied by five and added to the percentage hearing
37 loss for the ear with worse hearing and the sum of the
38 two divided by six.
39 Sec. . Section 85B.10, Code 2001, is amended to
40 read as follows:
41 85B.10 EMPLOYER'S NOTICE OF RESULTS OF TEST.
42 The employer shall communicate to the employee, in
43 writing, the results of an audiometric examination or
44 physical examination of an employee which reflects an
45 average hearing level in one or both ears in excess of
46 twenty-five decibels for the test frequencies of five
47 hundred, one thousand, two thousand, and three
48 thousand, and four thousand Hertz, as soon as
49 practicable after the examination. The communication
50 shall include the name and qualifications of the
