The purpose of this research was to discover the sound reflection material teaching to students who are deaf or hard of hearing by using solid objects as the reflection medium. The experimental method (pre-and post-test design) was used towards seven students who are deaf or hard of hearing ranging in age from 14 to 21 years. The oral method and experimental demonstration were used to deliver materials on sound reflection. The findings demonstrated that the material on sound reflection could be taught to students who are deaf or hard of hearing. Despite their inability to hear optimally, they understand that sound can be reflected and that there are factors that influence it. The ability of the teacher to explain the material and direct students when carrying out sound reflection experiments using tubes, classroom walls as reflective media, and sound level meters to measure the intensity of the sound source and the intensity of the reflected sound influences students' success in mastering the material. This success is greatly aided by their ability to read lip movements and perceive sounds. © School of Engineering, Taylor's University
