The tympanometer measures the admittance or compliance of the tympanic membrane while different pressures are being applied to the external ear canal. The compliance of the TM is measured in cubic centimeters, and the pressure in the ear canal is measured in decapascals (daPa).The probe has different size plugs that provide a seal at the entrance to the external ear canal.hysics of the Tympanogram. If the middle ear space is filled with fluid, most of the sound is reflected back to the probe from the stiff tympanic membrane. If the middle ear space is filled with air, and the ossicles are intact, energy is absorbed by the tympanic membrane, ossicles, and inner ear structures.

Other Seeds High in Iron (%DV per ounce (28g)): Sesame (23%), Sunflower (11%), and Flax (9%).
These foods also inhibit absorption.

Iron-Rich Vegetables. Beans and legumes are veggies rich in iron. A cup of canned white beans contains 8 milligrams, 1/2 cup of lentils contains 3 milligrams and 1/2 cup of kidney beans or chickpeas contains 2 milligrams.
