Teaching the Concept of Sound Waves using a Closed Organ Pipe for Students with Deaf and Hard of Hearing

Abstract

The goal of this research was to describe how to teach the concept of sound waves to Deaf and Hard of Hearing (DHH) students. The method used was the experimental method (pre-and post-test design) on 5 DHH students aged 12 to 16 years. The presentation of the sound wave concept material used both the speech method and the experimental method. The speech method included visual images, while the experimental method employed a closed organ pipe filled with water. A sound level meter was used to measure the intensity of the sound produced. The result of the study found that the material about the concept of sound waves could be taught to DHH students. The students could understand that sounds produce waves that propagate through the media (the experiment used water as the media) to reach the human ear. The teacher's communication style, the student's ability to read the teacher's lips, the student's sound perception, and the media used contributed to the success of conveying the concept of sound to DHH students.
