Young
people spend at least 45% of their school day engaged inlistening
activities, with today’s classroom acting as a primarily
auditory verbal environment.
However,
a recent study in the journal of the American Medical Association
showed that 14.9% of children aged 6~19 suffer from some degree
of hearing impairment, either permanently or temporarily due to
illness, infection or allergies.
Studies estimate that 80% of school children will have some form
of hearing loss during an academic year and, with the importance
of auditory learning in the classroom, the use of technology to
enhance listening performance ultimately allows children to learn
more efficiently.

One
of the simplest and most effective solutions is a ‘Sound Field
Voice Re-inforcement System’. Functioning like a mini public
address system in harmony with the classroom acoustics, Sound Field
Voice Re-inforcement features a wireless microphone, receiver, amplifier
and between one and four loudspeakers (dependent upon the size of
classroom). |

In a study of 8~10 year old students in the U.S. to test the effectiveness
of Sound Field Voice Re-inforcement in the classroom, students showed
an average improvement in identified spoken words of 45% using the
systems. Furthermore, when tested without a Sound Field System,
the children missed an average of 42% of the questions.
Within the school
utilised for the test, the principal, teachers and students completed
questionnaires regarding Sound Field Systems. Most stated that overall
attention spans improved, students followed the directions more
easily and they showed less hesitation when beginning their work.
The majority of students said it was easier to hear the teachers
and that the teachers did not have to yell or raise their voices.
In striving to plan successful academic programmes, teachers need
to consider the sheer numbers of students who may not hear well
on any given school day. Sound Field Voice Re-inforcement Systems
are an easy, cost effective way to address these issues, while also
ensuring that all students listen and learn productively throughout
the school year.

Section
1 of the Building Bulletin 93, the Government’s Specification
of Acoustic Performance sets the standards for the acoustics of
new buildings and explains the requirements and solutions to “...provide
acoustic conditions in schools that facilitate clear communications
of speech between teacher and students...”. |
|
 |
“...The
key aim of a (speech re-inforcement) system is to increase the loudness
of the direct sound, particularly for more distant listeners, whilst
keeping sound as natural as possible.
The distribution of loudspeakers and their directional characteristics
is a key issue in achieving high speech intelligibility. For large
teaching rooms and lecture theatres, loudspeakers can be distributed
in the ceiling...”
Furthermore, within Appendix 9: ‘Equipment Specifications
for sound field systems in schools’, the report states NXT
Loudspeakers and names Armstrong i-ceilings as recommended solutions;
“There are advantages in the use of these loudspeaker types,
as they provide a better average sound coverage in a room and provide
a better level of speech intelligibility under some conditions...
Less NXT type loudspeakers are required and it may be found that
one (loudspeaker) will suffice for the smaller classroom.”

All
children benefit from the improved speech clarity of a Sound Field
System. Academic improvements are noted in:
• Task behaviour
• Attentiveness
• Understanding of instructions
• Less repetition required
• Better attendance
• Improved measures of verbal recognition
|

The
application of Armstrong i-ceilings as a Sound Field Solution
also provides a unique and completely ‘invisible’
loudspeaker solution, ensuring the clean, simple lines of the
building’s interior are maintained. This inability to identify
the products also greatly decreases the possibilities of loudspeaker
theft or vandalism.
i-ceilings
exactly match over 90% of Armstrong suspended ceiling systems
sold in the UK - the most prevalent ceiling solution in the educational
establishment sector.
Furthermore, i-ceilings has proved in test after test to be installed
up to 75% faster than conventional ceiling speakers.
Armstrong
i-ceilings - already proving highly successful in leading
educational applications including York University Library, The
University of Edinburgh Medical School, Blyth Community College
and Loughborough University Sports Facility.
