This document discusses tympanometry, which is a test used to evaluate the function of the eardrum and middle ear. It describes how sound is transmitted through different media and factors like impedance, compliance, and pressure that are measured. There are three main types of tympanograms - A, B, and C - as well as normal tympanometry results. Clinical scenarios involving tympanometry are listed. The acoustic reflex test is also covered, noting it is simple, non-invasive, objective, and can be used for newborn babies.
Tympanometry
- 2. Principle Transmission of sound in different media. Impedance –stiffness,mass and friction. Complaince. Pressure .1dkp=1.02mm of water.
- 4. 220 or 226hz . Pressure +300 to -600 mm water. Normal complaince-0.35 to 1.40 ml. Normal pressure- +50dkpa to -50dkpa.
