8-PositionSound AlertTM

Monaural Listening Center

Model 1285G-08

Providing safe audio equipment

 

for group-basedenvironments

 

is critical in aiding students to

 

work and studytogether. The

 

8-positionSound 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 matching2924AVGmonaural headphones and a

 

rugged carry case. With the sound level controlled from its jackbox, the

 

listening center can safely keep the volume to a safe 85 decibel level.

 

When 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-HearingAssociation, 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.
