Access Board Information Meeting on Communication Access
- Part 3
Editor: There seems to be a growing awareness of the issues faced by
people with hearing loss in life-threatening and emergency situations. I
think it's a long ways from emerging awareness to the implementation of
effective systems, but awareness is certainly a start! Here's a report on
Lise Hamlin's recent presentation to the Access Board.

This is part three of four parts.

On July 25, 2006, the U.S. Access Board held a public meeting on
Communication Access in Washington, DC.
Communications Access at Drive-Thru Machines, Point of Sale Machines
- Banks, restaurants and other venders who use drive-thru availability
pose a communication problem for people who are deaf or hard of hearing.
NVRC urges the Access Board to set standards for those machines to provide
alternative means to access either automated voice menus or live voice over
speaker systems.
- Some possible solutions are:
· Voice to text: voice recognition systems would allow the speaker's
voice to be read as text by the user, with installation of a screen
available for those users who need it.
· Computers with touch screens: this would eliminate the need to use
voice at all. Such computers could show visuals as well as text to provide
access not only for people who are deaf or hard of hearing, but people with
English as a second language.
· Text to text: the consumer could type in a message for the staff
person, who could type back, using either computer technology, or short
messaging, or even something as simple as TTY technology.
- NVRC urges the access board to set standards for communication access
to point of sales machines and drive-thru machines, such as quick service
restaurants.
Acoustical Standards for the Classroom
- In their report, "Acoustics in Educational Settings," the American
Speech-Language-Hearing Association (ASHA) Workgroup on Classroom Acoustics
concludes that, "students of all ages and abilities, and their teachers need
appropriate classroom acoustics to communicate effectively in the classroom,
and other learning environments...The deleterious effect of poor acoustics
on students under age 15 and those with hearing and/or learning problems is
well documented." (American Speech-Language-Hearing Association. (2005)
Acoustics in educational settings: Technical report. Available at: http://www.asha.org/members/deskref-journals/deskref/default)
- Recognizing the trend of subpar acoustics in educational settings, the
American National Standards Institute (ANSI) introduced a standard for the
acoustical design of schools, S12.60-2002, "Acoustical Performance Criteria,
Design Requirements and Guidelines for Schools." (http://www.acoustics.com/ra_education_standard.asp
)
- According to Acoustics.Com (http://www.acoustics.com/ra_education_standard.asp),
"Many recent studies demonstrate that acoustics is a significant inhibitor
to productivity and that the presence of noise is directly related to lower
test scores. With the approval of this new standard, designers gain an
increased awareness of the importance of acoustics in educational facilities
and are given specific guidelines to help ensure the success of the
facility."
- Clearly, all children benefit from learning environments with good
acoustics, but for children with hearing loss, such environments are
critical. According to Carol Flexner (Flexer, Carol Ann. Facilitating
Hearing and Listening in Young Children. San Diego: Singular Publishing
Group, 1980.):
People with normal hearing typically require an S/N (Signal-to-Noise)
ratio of +6 dB for the reception of intelligible speech. Due to the auditory
distortion of the hearing loss itself, persons with a hearing problem need
an S/N ration of +20 dB (Finitzo-Heiber & Tillman, 1978; Hawkins, 1984). Due
to reverberation, noise, and changes in teacher position, the average
classroom S/N ratio is only +4 or +5 dB, and it may be 0 dB, which is less
than ideal even for children with normal hearing (Berg, 1986b, 1993). (Flexer,
p.96)
