Odiometry or Ear Ear: Evaluation of Hearing threshold
How is the Odiometry done?
To perform the Odiometric hearing test, you are in a acoustic and sound insulation chamber and a special headphone is placed on your ears. The audiologist (literate) distributes voices with frequencies (under and bumper) and different (high) intensities through the headphones. You are asked to hear the expert every time you hear a sound, even if it is too weak, by pressing a button or lifting a hand.
What does the Odiometric Results show?
Information obtained from the udiometry is crucial to prescribing hearing aids, planning for hearing rehabilitation, and following the patient's condition. At the Razi Specialized Auditory Center, we guarantee the most accurate results for respected clients using the most advanced basadometry equipment and standard chambers.
Tympanometry: Take a look at the health of the middle ear
Now we are going to the next important test. The difference between overdose and temphanomet is basically in their goal. While the udiometry measures the ability to hear you, the tympanometry examines the physical and functional condition of your middle ear. This test tells us how good the ear curtains and the small bones are behind it (hammer, Sandani and staircase). The middle ear is a space full of air whose air pressure must be equal to the pressure of the outside ambient air so that the ear curtain can move freely and transmit the sound well. Tempanometry evaluates exactly the same.
how is tympanometric?
This test is completely painless, fast and non -invasive. The audiologist puts a soft, small probe at the entrance of your ear canal. This probe does a few things at the same time:
What does tympanometric results show?
The results of this hearing test are displayed on a graph called "Tempanogram". A experienced audiologist at the Razi Specialized Specialist Center can identify the following problems by analyzing this chart:
Other Important Hearing Tests you need to know
The world of hearing evaluation is not limited to overdimeter and tympanometry. Depending on the patient's needs, age and symptoms, the Razi Specialized Auditory Center may also use other additional hearing tests:
1. Speech Evaluation
1. Acoustic Reflex Test
This test, often accompanied by tympanometry, measures the inhumane contraction of the small muscle of the middle ear (stapodius muscle) in response to loud noises. The absence of a reflex or its presence at non -divine levels can be a sign of middle ear problems, damage to the auditory nerve or even facial nerve.
1. Ear audio emission
This hearing test is an extraordinary way to evaluate the health of external hair cells in the cochlea (inner ear). In response to the sound, these cells emit a very weak acoustic energy that can be registered with a very sensitive microphone. The OAE test is rapid, non -invasive and objective, and is therefore used as the main tool in neonatal hearing screening programs around the world. The presence of a natural OAE response indicates the health of the internal ear.
1. Brain stem hearing responses
ABR test is an advanced electrophysiological test that records the electrical activity of the auditory nerve and its pathways in the brain stem in response to sound. This hearing test does not require the patient's cooperation and can be performed in a normal or sedative state. The main applications of ABR are:
conclusion
Understanding the difference between udiometry and tympanometry and getting to know other hearing tests is the first step in managing auditory health. Odiometry tells us how much we hear, while tempanometry examines the physical condition of the sound transmission system in the middle ear. These two tests, along with other assessments such as speech testing, OAE and ABR, provide a full and 2 degree image of your hearing system.
