In this interactive object, learners select the correct description of a child in the five stages of development in the following categories: pattern of growth, vital signs, organ development, vision and hearing, and developmental stage.
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
Have U "Herd" about these conditions of the Human Ear? Build your own band from a herd of mutant cows while reviewing conditions of the ear! Loss of hearing happens slowly and can go unnoticed. If you have trouble hearing on the phone, hearing birds, or work in a loud noisy environment. Get your hearing checked.
