Decibels (volume) are measured from low to high, top to bottom. Frequency (pitch) is measured from low to high, left to right.
The pink area is where normal hearing would fall - ie, all frequencies could be heard at at least 20db if not less. The yellow area, called the "speech banana", is where normal human speech falls. Vowels generally fall in the low, left end of this, and consonants on the right.
"O" marks the right ear and "X" marks the left. The horizontal ] bracket above the ear symbols marks the point of best bone conduction: when sound travels through the bones of the skull to the cochlea, bypassing the middle ear.
My audiogram from Dec of 08 shows loss in what's known as a "ski-slope" graph. I do ok with lower frequencies at medium volume, but as the pitch shifts higher and higher, my hearing gets worse and worse. I definitely struggle with speech, specifically with identifying consonants at the beginning of words.
Compare this to www.flickr.com/photos/tuliphead/562979440/. My left ear (which is my perceived dominant) has gotten much worse since then and I've lost much more in the high end on both ears.
In a word recognition test as part of this hearing test, I could only get 100% recognition at 95dB in the left ear and 85dB in the right. All hearing tests are done without hearing aids.
In summary, my hearing loss is moderate in low ranges, severe in middle ranges, and profound at 4000Hz and above.
