Providing safe audio equipment
for group-based environments
is critical in aiding students to
work and study together. The
8-position Sound Alert Listening
Center is the first of its kind to
warn teachers and students
when the audio that’s played
through the jackbox to its
headphones is louder than the
American Speech-Language-
Hearing Association’s
recommended 85dB level.
The center is ideal for
supporting audio-assisted
learning activities such as
individual and group tutorials,
literacy groups, language
lessons, story-time, Special
Education, and ELL/ELD learning
applications. It includes the
Sound Alert jackbox, eight matching 2924AVG monaural headphones and a
rugged carry case. ith the sound level controlled from its jackbox, the
listening center can safely keep the volume to a safe 85 decibel level.
hen the jackbox volume exceeds 85 decibels, a bright red LED warning
light turns on, alerting both the teacher and students about the unsafe
sound level requiring adjustment. This visual cue not only helps correct the
current situation, but will also help students learn safe and lifelong listening
practices in school and extending beyond their academic careers.
According to a March 2006 national poll commissioned by the American
Speech-Language-Hearing Association, 40% of students reportedly set their
music players’ volume too loud above 85 decibels, which is the level hearing
experts recommend not be exceeded. If music can be heard coming from a
student's headphone, the volume is too loud and the student is at risk of
experiencing hearing loss.
Hearing loss can lead to many problems in school including: difficulty with
academic achievement in language arts, vocabulary, arithmetic, and problem
solving. Students with hearing loss score lower on achievement tests, and
have greater needs for special education or extra support in the classroom.
The durable Sound Alert jackbox can also be used as a traditional jackbox
without charging its battery, but the warning LED feature will not operate.
The jackbox conserves its power by shutting off when no audio signal is
present for 60 seconds and will power on automatically when there is an
audio signal present.
