[nfbmi-talk] goes to signage braille raised characters and more

Mon Oct 20 16:44:49 UTC 2014

These are the structural communications requirements of the 2010 revised ADA standards and goes to the standards for raised character and Braille signage on every permanent room including room mumbers on Title II (state and local government buildings and more).These are technical standards, but the bottom line is most state buildings and local government buildings don't have these accessable signs.

That includes Cadillac Place, The State Library including the Braille and Talking Book Program, The Flint Office Building and our very State Capitol to name just a few.

704.2.2 Operable Parts. Operable parts shall comply with 309. Telephones shall have push-button controls where such service is available.

704.2.3 Telephone Directories. Telephone directories, where provided, shall be located in accordance with 309.

704.2.4 Cord Length. The cord from the telephone to the handset shall be 29 inches (735 mm) long minimum.

Block quote end

704.3 Volume Control Telephones. Public telephones required to have volume controls shall be equipped with a receive volume control that provides a gain

adjustable up to 20 dB minimum. For incremental volume control, provide at least one intermediate step of 12 dB of gain minimum. An automatic reset shall

be provided.

Advisory 704.3 Volume Control Telephones. Amplifiers on pay phones are located in the base or the handset or are built into the telephone. Most are operated

by pressing a button or key. If the microphone in the handset is not being used, a mute button that temporarily turns off the microphone can also reduce

the amount of background noise which the person hears in the earpiece. If a volume adjustment is provided that allows the user to set the level anywhere

from the base volume to the upper requirement of 20 dB, there is no need to specify a lower limit. If a stepped volume control is provided, one of the

intermediate levels must provide 12 dB of gain. Consider compatibility issues when matching an amplified handset with a phone or phone system. Amplified

handsets that can be switched with pay telephone handsets are available. Portable and in-line amplifiers can be used with some phones but are not practical

at most public phones covered by these requirements.

704.4 TTYs. TTYs required at a public pay telephone shall be permanently affixed within, or adjacent to, the telephone enclosure. Where an acoustic coupler

is used, the telephone cord shall be sufficiently long to allow connection of the TTY and the telephone receiver.

Advisory 704.4 TTYs. Ensure that sufficient electrical service is available where TTYs are to be installed.

Block quote start

704.4.1 Height. When in use, the touch surface of TTY keypads shall be 34 inches (865 mm) minimum above the finish floor.

EXCEPTION: Where seats are provided, TTYs shall not be required to comply with 704.4.1.

Block quote end

Advisory 704.4.1 Height. A telephone with a TTY installed underneath cannot also be a wheelchair accessible telephone because the required 34 inches (865

mm) minimum keypad height can causes the highest operable part of the telephone, usually the coin slot, to exceed the maximum permitted side and forward

reach ranges. (See Section 308).

Advisory 704.4.1 Height Exception. While seats are not required at TTYs, reading and typing at a TTY is more suited to sitting than standing. Facilities

that often provide seats at TTY's include, but are not limited to, airports and other passenger terminals or stations, courts, art galleries, and convention

centers.

704.5 TTY Shelf. Public pay telephones required to accommodate portable TTYs shall be equipped with a shelf and an electrical outlet within or adjacent

to the telephone enclosure. The telephone handset shall be capable of being placed flush on the surface of the shelf. The shelf shall be capable of accommodating

a TTY and shall have 6 inches (150 mm) minimum vertical clearance above the area where the TTY is to be placed.

705.2 Platform Edges. Detectable warning surfaces at platform boarding edges shall be 24 inches (610 mm) wide and shall extend the full length of the public

use areas of the platform.

706

Assistive Listening Systems

706.1 General. Assistive listening systems required in assembly areas shall comply with 706.

Advisory 706.1 General. Assistive listening systems are generally categorized by their mode of transmission. There are hard-wired systems and three types

of wireless systems: induction loop, infrared, and FM radio transmission. Each has different advantages and disadvantages that can help determine which

system is best for a given application. For example, an FM system may be better than an infrared system in some open-air assemblies since infrared signals

are less effective in sunlight. On the other hand, an infrared system is typically a better choice than an FM system where confidential transmission is

important because it will be contained within a given space.

The technical standards for assistive listening systems describe minimum performance levels for volume, interference, and distortion. Sound pressure levels

(SPL), expressed in decibels, measure output sound volume. Signal-to-noise ratio (SNR or S/N), also expressed in decibels, represents the relationship

between the loudness of a desired sound (the signal) and the background noise in a space or piece of equipment. The higher the SNR, the more intelligible

the signal. The peak clipping level limits the distortion in signal output produced when high-volume sound waves are manipulated to serve assistive listening

devices.

Selecting or specifying an effective assistive listening system for a large or complex venue requires assistance from a professional sound engineer. The

Access Board has published technical assistance on assistive listening devices and systems.

706.2 Receiver Jacks. Receivers required for use with an assistive listening system shall include a 1/8 inch (3.2 mm) standard mono jack.

706.3 Receiver Hearing-Aid Compatibility. Receivers required to be hearing-aid compatible shall interface with telecoils in hearing aids through the provision

of neckloops.

Advisory 706.3 Receiver Hearing-Aid Compatibility. Neckloops and headsets that can be worn as neckloops are compatible with hearing aids. Receivers that

are not compatible include earbuds, which may require removal of hearing aids, earphones, and headsets that must be worn over the ear, which can create

disruptive interference in the transmission and can be uncomfortable for people wearing hearing aids.

706.4 Sound Pressure Level. Assistive listening systems shall be capable of providing a sound pressure level of 110 dB minimum and 118 dB maximum with a

dynamic range on the volume control of 50 dB.

706.5 Signal-to-Noise Ratio. The signal-to-noise ratio for internally generated noise in assistive listening systems shall be 18 dB minimum.

706.6 Peak Clipping Level. Peak clipping shall not exceed 18 dB of clipping relative to the peaks of speech.

707

Automatic Teller Machines and

Fare Machines

Advisory 707 Automatic Teller Machines and Fare Machines. Interactive transaction machines (ITMs), other than ATMs, are not covered by Section 707. However,

for entities covered by the ADA, the Department of Justice regulations that implement the ADA provide additional guidance regarding the relationship between

these requirements and elements that are not directly addressed by these requirements. Federal procurement law requires that ITMs purchased by the Federal

government comply with standards issued by the Access Board under Section 508 of the Rehabilitation Act of 1973, as amended. This law covers a variety

of products, including computer hardware and software, websites, phone systems, fax machines, copiers, and similar technologies. For more information on

Section 508 consult the Access Board's website at www.access-board.gov.

707.1 General. Automatic teller machines and fare machines shall comply with 707.

Advisory 707.1 General. If farecards have one tactually distinctive corner they can be inserted with greater accuracy. Token collection devices that are

designed to accommodate tokens which are perforated can allow a person to distinguish more readily between tokens and common coins. Place accessible gates

and fare vending machines in close proximity to other accessible elements when feasible so the facility is easier to use.

707.2 Clear Floor or Ground Space. A clear floor or ground space complying with 305 shall be provided.

EXCEPTION: Clear floor or ground space shall not be required at drive-up only automatic teller machines and fare machines.

707.3 Operable Parts. Operable parts shall comply with 309. Unless a clear or correct key is provided, each operable part shall be able to be differentiated

by sound or touch, without activation.

EXCEPTION: Drive-up only automatic teller machines and fare machines shall not be required to comply with 309.2 and 309.3.

707.4 Privacy. Automatic teller machines shall provide the opportunity for the same degree of privacy of input and output available to all individuals.

Advisory 707.4 Privacy. In addition to people who are blind or visually impaired, people with limited reach who use wheelchairs or have short stature, who

cannot effectively block the ATM screen with their bodies, may prefer to use speech output. Speech output users can benefit from an option to render the

visible screen blank, thereby affording them greater personal security and privacy.

707.5 Speech Output. Machines shall be speech enabled. Operating instructions and orientation, visible transaction prompts, user input verification, error

messages, and all displayed information for full use shall be accessible to and independently usable by individuals with vision impairments. Speech shall

be delivered through a mechanism that is readily available to all users, including but not limited to, an industry standard connector or a telephone handset.

Speech shall be recorded or digitized human, or synthesized.

EXCEPTIONS:

1. Audible tones shall be permitted instead of speech for visible output that is not displayed for security purposes, including but not limited to, asterisks

representing personal identification numbers.

2. Advertisements and other similar information shall not be required to be audible unless they convey information that can be used in the transaction being

conducted.

3. Where speech synthesis cannot be supported, dynamic alphabetic output shall not be required to be audible.

Block quote start

Block quote end

Advisory 707.5 Speech Output. If an ATM provides additional functions such as dispensing coupons, selling theater tickets, or providing copies of monthly

statements, all such functions must be available to customers using speech output. To avoid confusion at the ATM, the method of initiating the speech mode

should be easily discoverable and should not require specialized training. For example, if a telephone handset is provided, lifting the handset can initiate

the speech mode.

Block quote start

707.5.1 User Control. Speech shall be capable of being repeated or interrupted. Volume control shall be provided for the speech function.

EXCEPTION: Speech output for any single function shall be permitted to be automatically interrupted when a transaction is selected.
