The softest sound you are able to hear at each pitch is recorded on the audiogram. The softenst sound you are able to hear is called your threshold. Thresholds of 0-25 dB are considered normal for adults and thresholds of 0-15 dB are considered normal for children. he vertical lines on an audiogram represent pitch or frequency. The 125 Hertz (Hz) vertical line on the left side of the audiogram represents a very low pitch sound and each vertical line to the right represents a higher pitch sound. Moving from left to right on the audiogram would be consistent with moving from left to right on a piano keyboard. The most important pitches for speech are 500-4000 Hz. When hearing is tested, the audiologist keeps track of exactly which tones each ear hears. Although some audiologists use a different form, most use a standard graph called the audiogram. The audiogram is a visual picture of what the ear hears. # PTA # HAT # OAE # REPORT # AUDIOGRAM # EAR # BERA VATSALYA SPEECH AND HEARING CONTACT NUMBER - 96387 10002, 74909 77070 #RAJKOT # JUNAGADH #JAMNAGAR #MORBI #UPLETA #JAMKHAMBHALIYA
