The purpose of this study was to analyze the different noise levels found in four agricultural mechanics facilities selected as being representative of the concrete and brick veneer type and the predominately steel type. The type of instructional programs considered were the laboratory skill oriented and the project construction oriented. A questionnaire was administered to students to determine: (1) what noises annoy them most, (2) which of eight characteristics causes it to be annoying, (3) what activities they are engaged in when annoyed most, and (4) students' perception of the aural environment. Speech interference levels were found by measuring the sound levels with a Bruel and Kjaer impulse precision sound level meter fitted with an octave filter set. The most annoying sounds to students were from: (1) pedestal and portable disc grinders, and (2) chipping and hammering slag. It was concluded that noise levels found in most agricultural mechanics facilities are not uncommon to what would be expected but that audio-communication is inhibited beyond a tolerable degree.
