Sound Alert
Monaural Headphone
The Sound AlertTM headphone
visibly signals to students and
teachers when the headphone
volume is louder than the
American Speech-Language-
Hearing Association recommended
85dB level.
When the volume that is played
through the headphone exceeds
85 decibels, a bright red warning
light on the earcup turns on,
alerting both the teacher and
student about an unsafe sound
level requiring adjustment.
Having an appropriate volume
level pointed out will help teachers
and students learn safe and
lifelong listening practices,
beginning in the classroom,
learning center, or school library.
According to a March 2006
national poll commissioned by
the American Speech-Language-
Hearing Association, 40% of
students reportedly set their
music players’ volume 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.
This durable headphone is based on the rugged Califone monaural headphone,
which is the educator’s standard for listening centers, ELL and ELD and other
language learning activities.
The Sound Alert headphone can be used as a normal headphone
without charging the battery, but the warning LED feature will
not operate. The headphone saves 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.
Also available is the 10-position Sound AlertTM monaural jackbox.
With the sound level monitored from this jackbox, the volume
from up to ten attached headphones (not needing to be the
2985PG) can be adjusted to the safe 85 decibel level.
