        ;;Narrative:  An examination of hearing impairment must be conducted by a
        ;;state-licensed audiologist and must include a controlled speech
        ;;discrimination test (specifically, the Maryland CNC recording) and a
        ;;pure tone audiometry test in a sound isolated booth that meets American
        ;;National Standards Institute standards (ANSI S3.1.1991) for ambient noise.
        ;;Measurements will be reported at the frequencies of 500, 1000, 2000, 3000,
        ;;and 4000 Hz.  The examination will include the following tests: Pure tone
        ;;audiometry by air conduction at 250, 500, 1000, 2000, 3000, 4000, and
        ;;8000 Hz, and by bone conduction at 250, 500, 1000, 2000, 3000, and
        ;;4000 Hz, spondee thresholds, speech recognition using the recorded
        ;;Maryland CNC Test, tympanometry and acoustic reflex tests, and, when
        ;;necessary, Stenger tests.  Bone conduction thresholds are measured 
        ;;when the air conduction thresholds are poorer than 15 dB HL.  A modified
        ;;Hughson-Westlake procedure will be used with appropriate masking.  A
        ;;Stenger must be administered whenever pure tone air conduction
        ;;thresholds at 500, 1000, 2000, 3000, and 4000 Hz differ by 20 dB or more
        ;;between the two ears.  Maximum speech recognition will be reported with
        ;;the 50 word VA approved recording of the Maryland CNC test.  When speech
        ;;recognition is 92% or less, a performance intensity function will be
        ;;obtained with a starting presentation level of 40dB re SRT.  If necessary,
        ;;the starting level will be adjusted upward to obtain a level at least 5 dB
        ;;above the threshold at 2000 Hz.  The examination will be conducted without
        ;;the use of hearing aids.  Both ears must be examined for hearing 
        ;;impairment even if hearing loss in only one ear is at issue.

        ;;              -------------
        ;;
        ;;              a.  Refer to 2507 for claimed disabilities.
        ;;
        ;;              b.  It veteran has filed a claim for tinnitus and there is a
        ;;                  current complaint of tinnitus, answer the questions above.
        ;;
        ;;              c.  If tinnitus is claimed and the veteran denies complaints
        ;;                  of tinnitus, answer no to the above question and do not
        ;;                  answer subsequent questions.
        ;;
        ;;              d.  If tinnitus is not claimed but the veteran reports a
        ;;                  complaint of tinnitus, then note the presence of tinnitus
        ;;                  and answer subsequent questions.
        ;;
        ;;C.  Physical Examination (Objective Findings):
        ;;
        ;;    1.  Measure puretone thresholds in decibels at the indicated
        ;;        frequencies (air conduction):

        ;;    *  The puretone threshold at 500 Hz is not used in determining the
        ;;       evaluation but is used in determining whether or not a ratable 
        ;;       hearing loss exists.  Puretone thresholds should not exceed 105
        ;;       decibels or the tolerance level.

        ;;
        ;;    When only puretone results should be used to evaluate hearing loss, 
        ;;    the examiner, who must be a state-licensed audiologist, should certify
        ;;    that language difficulties or other problems (specify what the problems
        ;;    are) make the combined use of puretone average and speech
        ;;    discrimination inappropriate.
        ;;
        ;;    Thresholds should not exceed 100 decibels or the tolerance level.
        ;;
        ;;D.  Diagnostic and Clinical Tests:
        ;;
        ;;    1.  Report middle ear status, confirm type of loss, and indicate
        ;;        need for medical follow-up.  In cases where there is poor
        ;;        inter-test reliability and/or positive Stenger test results,
        ;;        obtain and report estimates of hearing thresholds using a
        ;;        combination of behavioral testing, Stenger interference levels,
        ;;        and electrophysiological tests.
        ;;    2.  Include results of all diagnostic and clinical tests conducted
        ;;        in the examination report.
        ;;
        ;;E.  Diagnosis:
        ;;
        ;;    1.  Summary of audiologic test results.  Indicate type and degree 
        ;;        of hearing loss for the frequency range from 500 to 4000 Hz.
        ;;        For type of loss, indicate whether it is normal, conductive,
        ;;        sensorineural, central, or mixed.  For degree, indicate whether
        ;;        it is mild (26-40 HL), moderate (41-54 HL), moderately severe 
        ;;        (55-69 HL), severe (70-89 HL), or profound (90+ HL).
        ;;
        ;;    [For VA purposes, impaired hearing is considered to be a disability
        ;;    when the auditory threshold in any of the frequencies 500, 1000, 2000,
        ;;    3000, and 4000 Hz is 40 dB HL or greater; or when the auditory thresholds
        ;;    for at least three of these frequencies are 26 dB HL or greater; or when
        ;;    speech recognition scores are less than 94%]
        ;;
        ;;    2.  Note whether, based on audiologic results, medical follow-up
        ;;        is needed for an ear or hearing problem, and whether there is
        ;;        a problem that, if treated, might cause a change in hearing 
        ;;        threshold levels.
        ;;
        ;;    3.  If there is a current complaint of tinnitus, indicate whether or not
        ;;        tinnitus is as likely as not a symptom associated with hearing loss,
        ;;        if hearing loss is present.  If tinnitus is associated with
        ;;        conditions other than hearing loss indicate that the complaint of
        ;;        tinnitus requires referral to another provider (appropriate provider
        ;;        to be determined by C&P Director) for determination of etiology.
