One of the most common ways to assess your child's hearing ability is through an audiogram, which is basically a picture of your child's hearing. The vertical line demonstrates frequency and pitch; the horizontal line captures loudness and intensity. Overall, an audiogram charts the weakest intensity of sound heard by your child. Usually, the human ear can detect frequencies from 20 to 20,000 Hz (cycles per second). The results of audiometric tests diagnose hearing loss or diseases of the ear. This is a very common procedure.
