HEARING GRAPHIC: AN AUDIOGRAM FOR PAIN, MUSIC, & SPOKEN LANGUAGE. KEY: The BLACK LINE represents the average threshold for causing physical PAIN to the human ear; right up to that line is the BLUE section, which contains ALL the frequency & volume variations humans can hear w/o pain; within that, a DOTTED LINE & a PINK section show where MUSIC's sound fits in; and then the center YELLOW shows where spoken LANGUAGE sounds are heard. A pretty cool use of a pretty old graph! #Audiology #Deaf #HOH
