 ;;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.  Review of Medical Records: Indicate whether the C-file was reviewed.

 ;;

 ;;B.  Medical History (Subjective Complaints):

 ;;

 ;;      Comment on:

 ;;

 ;;        1.  Chief complaint.

 ;;        2.  Situation of greatest difficulty.

 ;;        3.  Pertinent service history.

 ;;        4.  History of military, occupational, and recreational noise

 ;;            exposure.

 ;;        5.  Pertinent family and social history; history of ear disease,

 ;;            head or ear trauma, etc.

 ;;        6.  Tinnitus - Is there a current complaint of tinnitus? (yes/no)

 ;;            If yes, indicate the following:

 ;;

 ;;              a.  Date and circumstances of onset.

 ;;              b.  Whether it is unilateral or bilateral.

 ;;              c.  Whether it is constant or recurrent.

 ;;              d.  If recurrent (intermittent), indicate the frequency and

 ;;                  duration of tinnitus episodes.

 ;;

 ;;              INSTRUCTIONS:

 ;;              -------------

 ;;

 ;;              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):

 ;;

 ;;    = = = = =RIGHT EAR= = = = = = = = = = = = = LEFT EAR = = = = = = 

 ;;    A*    B    C    D    E    **       A*   B    C   D    E     **

 ;;    500|1000|2000|3000|4000|average   500|1000|2000|3000|4000|average

 ;;       |    |    |    |    |             |    |    |    |    |

 ;;  

 ;;    *  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.

 ;;    ** The average of B, C, D, and E.

 ;;

 ;;    2.  Speech Recognition Score: Maryland CNC word list

 ;;

 ;;                         _____% right ear _____% left ear.

 ;;

 ;;    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.
