## tympanogram_types.jpg

The image is a scientific diagram illustrating different types of tympanograms, which are used in audiology to measure how well sound travels through the ear canal into the middle ear. The diagram includes four separate graphs labeled as Type A_s, Type B, Type A_d, and Type C.

Each graph shows two axes: one for "Air Pressure (daPa)" on the horizontal axis ranging from -400 daPa to 200 daPa, and another for "Admittance (mmho)" on the vertical axis ranging from 0.0 mmho to 2.5 mmho.

1. **Type A_s**: This graph shows a single peak at around +80 daPa with minimal admittance values.
   
2. **Type B**: This graph also has one peak, but it is located closer to the origin (around -60 daPa) and has higher admittance values compared to Type A_s.

3. **Type A_d**: This graph features two peaks: a smaller one at around +80 daPa with low admittance and another larger peak at around 15 daPa, which is much higher in admittance.
   
4. **Type C**: This graph has a single peak located near -200 daPa with high admittance values.

The labels "Type A_s," "Type B," "Type A_d," and "Type C" are written above each respective graph to identify the type of tympanogram being depicted. The diagram is sourced from Kramer & Brown's book titled "Audiology: Science to Practice."

There are no people or characters in this image, only graphs representing different types of tympanograms used in audiology.
