¶1 The case presents four issues:  Was the evaluation of a noise-induced hearing loss exempted from the statutory requirement that the rating physician assess [643 P.2d 313] permanent impairment by substantially complying with the American Medical Association's "Guides to the Evaluation of Permanent Impairment" [AMA Guides]?  Does the expert evaluation of hearing loss lack probative value because it was based on the allegedly outmoded "whisper" test?  Was the noise-induced hearing loss an accidental injury to a scheduled member rather than an occupational disease? and  Was the trial tribunal required to find loss of earning power or ability to work as a precondition to awarding compensation for the impairment of a scheduled member?
¶2 We answer the first and third questions in the affirmative and the second and fourth in the negative.
¶3 The claimant, a welder, has been in the Peabody Galion Corporation's [employer] employ for approximately 5 years. His workplace was a large, open structure in which various departments were housed in proximity one to the other. His welding assignments took him to different locations within the plant where he was subjected to a broad range of noises. Among the identified noise sources were diesel motors, grinders, chipping hammers, breaks and punch presses. Aside from these, there were also noises from manual hammering within metal confinement and the blowing of a large air whistle close to the work station. No plant personnel were provided with, nor required to wear, earplugs.
¶4 The claimant initially noticed a hearing problem around November 1978. It was then that a constant ringing sensation in his ears came to manifest itself. He found himself continually increasing the volume on the television set and asking others to repeat comments directed to him. After discussing the problem with other employees, the claimant sought the advice of a doctor. In April 1979 his condition came to be diagnosed as a noise-induced hearing loss. During the same month he brought a compensation claim.
¶5 At the hearing, Dr. D, the employer's medical expert, testified that upon examining the claimant, he ordered several audiometric tests and then applied the AMA standards to the results of the tests to arrive at an evaluation of the claimant's condition. He explained that the AMA standards were not adjusted for age - a factor which he felt was highly important. As a result, he combined the percentages indicated by the AMA standards with aging tables published by the National Institute for Occupational Safety and Health to reach a final evaluation of 6.75 per cent loss of hearing to the left ear and 16 per cent loss of hearing to the right ear - for a binaural average of 8.3 per cent disability. Dr. D noted that when tested for spoken-word comprehension, the claimant required volumes significantly higher than the normal listener. On cross-examination he said the AMA evaluation procedure did not cover the full range of the claimant's hearing loss.
¶6 Dr. M, the claimant's physician, testified there was a hearing loss of 30 per cent to the right ear and 20 per cent to the left ear - for a combined hearing loss of 45 per cent. In evaluating the claimant's disability, he deviated from the AMA Guides and used a spoken-word procedure [whisper test] to determine the claimant's ability to hear spoken language under everyday conditions. His decision not to use the AMA Guides resulted from his belief that the AMA Guides did not correctly reveal the amount of disability in a man of the claimant's age. While before writing his report Dr. M reviewed the results of audiometric testing run by the employer's physician, he did not rate the claimant's disability according to the AMA standards.
¶7 The trial tribunal found that claimant's loss of hearing from continued exposure to loud noise constituted an occupational disease. He was awarded a 30 per cent loss of hearing to the right ear and 18 per cent loss of hearing to the left ear - for a binaural hearing loss of 25 per cent permanent partial disability. The award was affirmed by the appellate panel of the Workers' Compensation Court. The employer brings this proceeding for review.

¶8 The employer contends that 85 O.S.Supp. 1977 § 3 (11)
¶9 The question posed was recently addressed in B.F. Goodrich v. Hilton
¶10 The employer next contends that, even if we allow the exception to using the AMA Guides, the claimant's medical evidence is without probative value because it is based on the spoken word or "whisper" test. The medical evidence so obtained, the employer argues, is speculative and without a scientific basis so as to require vacation of the award.
¶11 The claimant's physician, after reviewing the AMA Guides and concluding they would not correctly mirror the limits of the claimant's hearing disability, chose an alternative evaluation procedure known as the "whisper" test. This procedure relies on responses to vocalization at various degrees of loudness. The employer urges us to declare the results of this procedure inadmissible and confine the evidence in the case to the evaluation by the employer's expert - based on electronic audiometric testing - even though such testing admittedly did not reflect the full range of the claimant's hearing impairment.
¶12 The "whisper" test was in wide use before the availability of electronic audiometric testing. The record does not show that the technique of whisper testing is either discredited or discarded by the present state of the art or is so out-of-date as to constitute a scientifically inaccurate or unreliable method. To the contrary, the record reveals a medically recognized need and desirability for ascertaining a person's ability to hear and comprehend ordinary spoken language.
¶13 In cases in which evaluation of disability depends on expert medical opinion, an award must be supported by competent evidence.
¶14 The record reveals the award rests on competent evidence. We are powerless to disturb it.
¶15 The employer asserts error in characterizing the claimant's disability as an occupational disease instead of accidental injury. The claimant argues that it was the legislative intent to include loss of hearing within the broadened definition of occupational disease when the statute was amended in 1977. 85 O.S.Supp. 1977 § 3 (10).
¶16 Before the 1977 revision of § 3(10), the term "occupational disease" was narrowly construed. It was limited to diseases listed or described in the statute.
¶17 The fundamental purpose in statutory interpretation is to ascertain the intent of the [643 P.2d 316] legislature.
¶18 The trial tribunal classified the claimant's loss-of-hearing disability as an occupational disease which resulted from continued exposure to loud noises. Implicit in its award is a finding that a series of successive micro-traumatic on-the-job events did in fact occur in the manner that unfolded itself from the testimony and that these harmful events did ultimately produce the disability for which compensation was claimed.
¶19 The claimant's injury was the unexpected result of certain extrinsic conditions, as distinguished from some systemic reaction of internal origin which is the customary or natural result of an occupation or industry. The impairment to the claimant's hearing was not shown to be characteristic of, or peculiar to, the welding trade so as to bring it exclusively within the definition of an occupational disease. We have long recognized that hearing loss resulting from prolonged exposure to loud or concussive noise is an accidental injury.
¶20 In mislabeling the hearing disability as a disease, the trial tribunal made an incorrect choice between two alternatives in a case of first impression. The legal predicate used as a basis for the award - the occupational disease - does not constitute an error in the fact finding process but a mischaracterization of the legal foundation for the award. This error does not require that we vacate the award. It may be treated as one of law which we are not powerless to correct on review.
¶21 The medical diagnosis of the cumulative effect of the harm-dealing noise was made in April 1979. April would also be considered the date of his last exposure according to the claim for compensation on file.
¶22 The amount of the award would not be different under either classification.
¶23 The employer's last assignment of error is that the Workers' Compensation Court could not award compensation absent a showing of loss of earning power or loss of ability to work.
¶24 This question has been thoroughly explored in discussing the method of compensating injuries to § 22 scheduled members. We have consistently held that compensation for accidental loss of function in a scheduled member must be paid without regard to an impairment of claimant's earning power.
¶25 Award sustained as modified.

2 The terms of Rule 23 of the Workers' Compensation Court provide: "The court adopts the `Guides to the Evaluation of Permanent Impairment' as published in 1977 by the American Medical Association, for use by examining physicians as a guideline in their evaluations of all permanent impairments with the exception of loss of use or amputations of scheduled members. In case of any conflict between the `Guides' and the provisions of 85 O.S.Supp. 1977 § 22 , the latter shall control and prevail. In any case where the examining physician deviates from the `Guides' the basis for the deviation shall be stated with full medical explanation."

5 Competent medical testimony under § 17 is an evaluation by a physician within the meaning of § 14. Under § 14 the term "physician" means "any person licensed in Oklahoma as a Medical Doctor, Chiropractor, Chiropodist, Dentist, Osteopathic Physician or Optometrist".
7 According probative value to the evidence is a process of assessing proper weight and value and hence one within the exclusive province of the fact trier. When absence of probative value is asserted on review, a pure question of law is presented. Bergstrom Painting Co. v. Pruett, 205 Okl. 291, 237 P.2d 453, 454 ; Sparks v.

19 The trial tribunal's finding of occupational disease resulted from an incorrect choice of the legal predicate used. That choice is correctable on review because we are not powerless to make the findings conformable to the applicable law. Oklahoma Pipe Line Co. v. Putnam, 162 Okl. 52, 18 P.2d 1095, 1097 .
20 A lower weekly rate of $60 was in effect in 1978, the year in which the effects of claimant's injuries were first manifested, although undiagnosed. The rate was increased to $70 in 1979. 85 O.S.Supp. 1977 § 22 (6).
