Promoting the Usefulness of Classroom

Amplification Equipment (Summary)

Educational Audiology Monograph, 1993, 3, pp. 32-33

Laurie Allen

The use of sound field amplification equipment has been found to be an

innovative prevention/intervention strategy for students in almost all educational

settings. Research has documented that there exists a positive correlation

between the use of classroom amplification and improved student academic

achievement.

Sound field amplification systems typically include a transmitter/microphone, a

receiver, a two channel amplifier and four speakers. The use of sound field

amplification has many advantages in education including students who are more

attentive and less distracted and teachers who require fewer direction

repetitions. Teachers are able to speak normally without having to strain their

voice which leads to reduced vocal abuse.

After a sound field amplification system is installed, principals should be

encouraged to spend time in the classroom to have firsthand experience. Also,

students and teachers should fill out feedback questionnaires to show the

benefits of using sound field amplification in classrooms to school boards,

superintendents and local service organizations.

Ninety (90) elementary school teachers were surveyed regarding the usefulness

of different classroom equipment. Each teacher was asked to prioritize the same

list of equipment and rank them according to their usefulness. The list included:

• A cassette tape recorder

• An overhead projector

• A television

• A sound field classroom amplification system (CAE)

• A camcorder movie camera

• A computer

…cont’d

• A television with VCR

• A computer with a CD ROM player

• A filmstrip projector

The survey shows that once the teachers became familiar with the system, they

ranked it higher than overhead projectors, televisions, and computers. Also, once

teachers had the opportunity to use an amplification system, they were reluctant

to give it up. The comparative data documents the potential power of sound field

classroom amplification equipment.

Classroom amplification equipment is a flexible audio enhancement tool that

benefits both teacher and students and makes very little demands on the teacher.

It is user friendly and takes up little space in the classroom. It can be directly

connected to cassette tape recorders, CD players, and television sets. By

relying on the amplification system, the teacher can easily talk over interfering

background noise such as fans, band practice, computers, or overhead

projectors.
