The Effect Sound Field Amplification has

on Teacher Vocal Abuse Problems

(Summary)

Laurie Allen, M.A. CCC-Aud.

Keystone Area Education Agency, Dubuque, Iowa

During the 1994-95 school year approximately 56% of 141 Dubuque, Iowa public

elementary school teachers reported that they typically suffer from vocal

abuse/fatigue problems at least once during each school year. 60% (85 total) of

these teachers had never used sound field amplification equipment. It was

estimated that these teachers took a total of 59 sick days each school year

because of vocal maladies (.7 sick days per teacher). 40% (56 total) of the

teachers did have experience using sound field classroom amplification

equipment. It was estimated that when these teachers were without the

amplification equipment, they averaged 52 sick days per year because of voice,

jaw, or throat problems (.93 sick days per teacher). However, when they used the

amplification equipment, they estimated that they took only 19 sick days per year

(.34 days/ teacher).

It should be noted that about half of the teachers in this subgroup had histories of

chronic voice problems. Almost all of the teachers reported that the sound field

amplification equipment was user friendly and made it easier for them to project

their voices throughout the classroom.

This data suggests that an increased use of sound field amplification equipment

would result in substantial annual savings for the school district in substitute

teacher pay. The Dubuque Community Schools currently employs approximately

650 full time teachers. Their substitute teacher pay is approximately $62 per day.

12-14 unused sick days saved by the district would cover the cost of an

additional classroom amplification system.
