HEARING LOSSHEARING LOSSI. IntroductionA. Compensable hearing loss results from damage to the hearing organs orauditory cortex as a result of employment. Hearing loss may occur in one orboth ears and is either noise-induced or caused by physical trauma.B. For purposes of impairment rating, the term noise-induced hearing lossrefers to slowly progressive neurosensory impairment resulting fromprolonged exposure to hazardous sound.C. Occupational noise-induced hearing loss may affect one or both earsdepending on the noise source and proximity. If such hearing loss is bilateral,both ears are affected to similar degree.D. Hearing loss from trauma refers, for purposes of rating impairment, tosuddenly acquired loss resulting from physical trauma to the skull or ear, orfrom exposure to sudden, intensive acoustic energy such as gunfire, loudimpacts and explosions.II.Rating ProcedureA. Total the 4 pure tone audiometric results of hearing in one ear obtained at500 Hz, 1000 Hz, 2000 Hz and 3000 Hz without the use of a hearing aid.B. Repeat using results obtained from the other ear.C. Compare the totals.If the hearing loss is bilateral and the losses in each ear,i. differ by less than 20dB, apply each total to the appropriate axis of Table1, to obtain the combined PCI rating (see Example 1, page 38).ii. differ by more than 20dB, assume the loss in the better ear is due tooccupational noise exposure. Apply that loss to both axes of Table 1 toobtain the combined PCI rating (see Example 2, page 38).Page 36COPYRIGHT 2006 All Rights Reserved October 1, 2006
HEARING LOSSD. The calculated PCI rating is apportioned for the Alberta caused loss.III.Specific Rules in RatingA. ISO audiometric calibration must be used for frequency specific hearing lossmeasurement.B. Effects of aging on hearing ability (presbycusis) are not considered in ratinghearing impairment because the average hearing loss at 500 Hz, 1000 Hz,2000 Hz and 3000 Hz due to presbycusis falls below 35 decibels.C. Tinnitus alone produces no impairment.D. Tinnitus in the presence of measurable hearing loss (unilateral or bilateral)with impairment of speech discrimination in the poorer ear, may be rated upto 2% impairment on a judgement basis in addition to the rating for thehearing loss.E. Tinnitus in the presence of (physical) cochlear or acoustic trauma with orwithout measurable hearing loss may be rated up to 2% on a judgementbasis.Page 37COPYRIGHT 2006 All Rights Reserved October 1, 2006
