For notes in the range of 1500-4000 Hz, I cannot hear at all with my right ear, and have very little hearing with my left ear. I have more hearing for the low notes than the high notes. You can see that for the most part I am profoundly deaf, though there are a few frequencies in the ’severe’ range, which co-incide with Middle C on the piano keyboard. You can see entries in the chart in blue for my left ear and red for my right. A circle or cross with a downward arrow on the audiogram indicates that I cannot hear that pitch at all.
Sounds you can hear at a quiet level (a low number of decibels) are at the top, and sounds that you can only hear if they are very loud are down the bottom (a high number of decibels). The numbers up the left side of the chart represent how loud the sound needs to be before you can hear it. You can see that Middle C on the piano is just above 250 Herz. On the left are the low notes (250 Hz), and on the right are the high notes (up to 9000 Hz). To understand your audiogram, think of the numbers across the bottom, the herz, as representing keys on the piano. Maybe 100 decibels? The detailed answer is that you can look at your audiogram to check.
How much hearing do you need to access this course?
