Marketing Information |
The Sound Alert™ 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. |
