Purpose 5

PURPOSE

In a typical classroom environment, a teacher

in front of the room lectures to a room filled with 30

or 40 students. Those students in the first few rows

can easily hear what the teacher is saying, but those

further back in the classroom frequently find that

hearing the teacher over the ambient noise of the

room can be considerably more difficult. This

frequently leads to lack of comprehension, inatten-

tion, disorder, teacher fatigue, and a generally less

than ideal learning environment.

The R. L. Drake SRR60 Sound Reinforcement

Receiver and associated system microphones, IR

sensors, and speakers, successfully addresses this

problem by supplying the teacher with a lavaliere

microphone which transmits his or her voice by

infrared (IR) signals to sensors placed at strategic

locations around the classroom. These sensors pick

up the infrared signals and feed them to the SRR60

Receiver which, in turn detects and amplifies them

and feeds the teacher’s voice to loudspeakers placed

in such a way as to provide equal sound volume to all

points in the room. In this way, all students in the

room have equal access to what

the teacher is saying, which greatly improves

attentiveness and comprehension for those students

farthest from the teacher, which in turn results in less

teacher stress.

A hand held IR microphone is typically used

with the system and can be passed to students who

are responding to questions, or are otherwise

contributing in class discussions. The SRR60

Receiver also accepts external audio inputs from

various audio-visual aids such as CD and DVD

players, VCRs, TVs and computers.

Two audio outputs are provided for feeding

audio recorders, or assistive listening transmitters to

accommodate those with impaired hearing.

While the SRR60 was designed with classrooms

in mind, it will provide just as great a benefit when

used in any similar environment such as meeting

rooms, large conference rooms, churches, etc.
