Sec. 801.420  Hearing aid devices; professional and patient labeling.

    (a) Definitions for the purposes of this section and Sec. 801.421. 
(1) Hearing aid means any wearable instrument or device designed for, 
offered for the purpose of, or represented as aiding persons with or 
compensating for, impaired hearing.
    (2) Ear specialist means any licensed physician who specializes in 
diseases of the ear and is medically trained to identify the symptoms of 
deafness in the context of the total health of the patient, and is 
qualified by special training to diagnose and treat hearing loss. Such 
physicians are also known as otolaryngologists, otologists, and 
otorhinolaryngologists.
    (3) Dispenser means any person, partnership, corporation, or 
association engaged in the sale, lease, or rental of hearing aids to any 
member of the consuming public or any employee, agent, sales person, 
and/or representative of such a person, partnership, corporation, or 
association.
    (4) Audiologist means any person qualified by training and 
experience to

[[Page 33]]

specialize in the evaluation and rehabilitation of individuals whose 
communication disorders center in whole or in part in the hearing 
function. In some states audiologists must satisfy specific requirements 
for licensure.
    (5) Sale or purchase includes any lease or rental of a hearing aid 
to a member of the consuming public who is a user or prospective user of 
a hearing aid.
    (6) Used hearing aid means any hearing aid that has been worn for 
any period of time by a user. However, a hearing aid shall not be 
considered ``used'' merely because it has been worn by a prospective 
user as a part of a bona fide hearing aid evaluation conducted to 
determine whether to select that particular hearing aid for that 
prospective user, if such evaluation has been conducted in the presence 
of the dispenser or a hearing aid health professional selected by the 
dispenser to assist the buyer in making such a determination.
    (b) Label requirements for hearing aids. Hearing aids shall be 
clearly and permanently marked with:
    (1) The name of the manufacturer or distributor, the model name or 
number, the serial number, and the year of manufacture.
    (2) A ``+'' symbol to indicate the positive connection for battery 
insertion, unless it is physically impossible to insert the battery in 
the reversed position.
    (c) Labeling requirements for hearing aids--(1) General. All 
labeling information required by this paragraph shall be included in a 
User Instructional Brochure that shall be developed by the manufacturer 
or distributor, shall accompany the hearing aid, and shall be provided 
to the prospective user by the dispenser of the hearing aid in 
accordance with Sec. 801.421(c). The User Instructional Brochure 
accompanying each hearing aid shall contain the following information 
and instructions for use, to the extent applicable to the particular 
requirements and characteristics of the hearing aid:
    (i) An illustration(s) of the hearing aid, indicating operating 
controls, user adjustments, and battery compartment.
    (ii) Information on the function of all controls intended for user 
adjustment.
    (iii) A description of any accessory that may accompany the hearing 
aid, e.g., accessories for use with a television or telephone.
    (iv) Specific instructions for:
    (a) Use of the hearing aid.
    (b) Maintenance and care of the hearing aid, including the procedure 
to follow in washing the earmold, when replacing tubing on those hearing 
aids that use tubing, and in storing the hearing aid when it will not be 
used for an extended period of time.
    (c) Replacing or recharging the batteries, including a generic 
designation of replacement batteries.
    (v) Information on how and where to obtain repair service, including 
at least one specific address where the user can go, or send the hearing 
aid to, to obtain such repair service.
    (vi) A description of commonly occurring avoidable conditions that 
could adversely affect or damage the hearing aid, such as dropping, 
immersing, or exposing the hearing aid to excessive heat.
    (vii) Identification of any known side effects associated with the 
use of a hearing aid that may warrant consultation with a physician, 
e.g., skin irritation and accelerated accumulation of cerumen (ear wax).
    (viii) A statement that a hearing aid will not restore normal 
hearing and will not prevent or improve a hearing impairment resulting 
from organic conditions.
    (ix) A statement that in most cases infrequent use of a hearing aid 
does not permit a user to attain full benefit from it.
    (x) A statement that the use of a hearing aid is only part of 
hearing habilitation and may need to be supplemented by auditory 
training and instruction in lipreading.
    (xi) The warning statement required by paragraph (c)(2) of this 
section.
    (xii) The notice for prospective hearing aid users required by 
paragraph (c)(3) of this section.
    (xiii) The technical data required by paragraph (c)(4) of this 
section, unless such data is provided in separate labeling accompanying 
the device.
    (2) Warning statement. The User Instructional Brochure shall contain 
the following warning statement:

[[Page 34]]

                    Warning to Hearing Aid Dispensers

    A hearing aid dispenser should advise a prospective hearing aid user 
to consult promptly with a licensed physician (preferably an ear 
specialist) before dispensing a hearing aid if the hearing aid dispenser 
determines through inquiry, actual observation, or review of any other 
available information concerning the prospective user, that the 
prospective user has any of the following conditions:
    (i) Visible congenital or traumatic deformity of the ear.
    (ii) History of active drainage from the ear within the previous 90 
days.
    (iii) History of sudden or rapidly progressive hearing loss within 
the previous 90 days.
    (iv) Acute or chronic dizziness.
    (v) Unilateral hearing loss of sudden or recent onset within the 
previous 90 days.
    (vi) Audiometric air-bone gap equal to or greater than 15 decibels 
at 500 hertz (Hz), 1,000 Hz, and 2,000 Hz.
    (vii) Visible evidence of significant cerumen accumulation or a 
foreign body in the ear canal.
    (viii) Pain or discomfort in the ear.
    Special care should be exercised in selecting and fitting a hearing 
aid whose maximum sound pressure level exceeds 132 decibels because 
there may be risk of impairing the remaining hearing of the hearing aid 
user. (This provision is required only for those hearing aids with a 
maximum sound pressure capability greater than 132 decibels (dB).)

    (3) Notice for prospective hearing aid users. The User Instructional 
Brochure shall contain the following notice:

           Important Notice for Prospective Hearing Aid Users

    Good health practice requires that a person with a hearing loss have 
a medical evaluation by a licensed physician (preferably a physician who 
specializes in diseases of the ear) before purchasing a hearing aid. 
Licensed physicians who specialize in diseases of the ear are often 
referred to as otolaryngologists, otologists or otorhinolaryngologists. 
The purpose of medical evaluation is to assure that all medically 
treatable conditions that may affect hearing are identified and treated 
before the hearing aid is purchased.
    Following the medical evaluation, the physician will give you a 
written statement that states that your hearing loss has been medically 
evaluated and that you may be considered a candidate for a hearing aid. 
The physician will refer you to an audiologist or a hearing aid 
dispenser, as appropriate, for a hearing aid evaluation.
    The audiologist or hearing aid dispenser will conduct a hearing aid 
evaluation to assess your ability to hear with and without a hearing 
aid. The hearing aid evaluation will enable the audiologist or dispenser 
to select and fit a hearing aid to your individual needs.
    If you have reservations about your ability to adapt to 
amplification, you should inquire about the availability of a trial-
rental or purchase-option program. Many hearing aid dispensers now offer 
programs that permit you to wear a hearing aid for a period of time for 
a nominal fee after which you may decide if you want to purchase the 
hearing aid.
    Federal law restricts the sale of hearing aids to those individuals 
who have obtained a medical evaluation from a licensed physician. 
Federal law permits a fully informed adult to sign a waiver statement 
declining the medical evaluation for religious or personal beliefs that 
preclude consultation with a physician. The exercise of such a waiver is 
not in your best health interest and its use is strongly discouraged.

                       children with hearing loss

    In addition to seeing a physician for a medical evaluation, a child 
with a hearing loss should be directed to an audiologist for evaluation 
and rehabilitation since hearing loss may cause problems in language 
development and the educational and social growth of a child. An 
audiologist is qualified by training and experience to assist in the 
evaluation and rehabilitation of a child with a hearing loss.

    (4) Technical data. Technical data useful in selecting, fitting, and 
checking the performance of a hearing aid shall be provided in the User 
Instructional Brochure or in separate labeling that accompanies the 
device. The determination of technical data values for the hearing aid 
labeling shall be conducted in accordance with the test procedures of 
the American National Standard ``Specification of Hearing Aid 
Characteristics,'' ANSI S3.22-1996 (ASA 70-1996) (Revision of ANSI 
S3.22-1987), which is incorporated by reference in accordance with 5 
U.S.C. 552(a) and 1 CFR part 51. Copies are available from the Standards 
Secretariat of the Acoustical Society of America, 120 Wall St., New
