We provide professional support in Audiometry.
Hearing is measured according to two main components. These are the frequency and
intensity of sound. The audiometry test measures the hearing of a person
at various frequency levels (measured in decibels) at various frequency levels
(Hz. a method used to measure and graph. Although it is often used to test
young children and older adults who are at risk for hearing, it is also used in
a successful hearing loss prevention program. Audiometry screening is not a
mixed test and requires minimal instrumentation.
An audiometry device has a converter to convert
electrical impulses to sound or vibrations from a variable frequency oscillator
producing electrical pulses along audible, perceptible frequencies, and a
attenuator to create variations in intensity. The device can be either a
fixed part of a designated test facility or a portable unit with a variety of
settings flexibility for use. An air-conduction audiogram is produced when
the sound is transmitted through the headset or through an earpiece inserted by
the patient and the patient’s responses are recorded. The air conduction
audiometry device evaluates both sensorineural and conductive hearing.
The cochlea of the inner ear, sensorineural hearing auditory nerve and the cochlear nucleus
refers to those that are produced by the brain. Sensorineural hearing loss
has both acquired and congenital causes. A bone conduction audiogram is
performed to test only sensorineural hearing. In this method, a
bone-conduction oscillator or vibrator is held against the mastoid process or
forehead, similar to using a setting fork when performing physical
examination. The vibrator, which is usually fixed with a headband, causes
the fluid in the cochlea to deteriorate by making the skull
oscillate. This disturbance is detected by cochlea and is transmitted from
the auditory nerve to the cochlear cores without using the middle ear
system. The results are rated as bone conduction audiogram. Impaired
with sensorineural hearing loss both air and bone conduction and pure disorders
is about the same. The Test takes 5-10 minutes.
General screening of children at the earliest possible age,
If you are exposed to one of the sensorineural hearing loss causes (or more) ,
Finding late speech in children,
Persistent behavior problems, in children or in the
elderly to find the cause of changes,
Especially geriatric evaluation should be screened for the elderly,
What causes hearing loss?
Persistent serous otitis media, especially in children, bilateral cases
Suffering with suspected hearing loss that is applied to
everyone (usually a conductive hearing loss refers to an abnormal tympanogram;
however, sensorineural hearing loss causes)
In an audiometric evaluation of a failed screening test
Tinnitus, vertigo, or dizziness complaints
After severe head trauma
After the use of ototoxic drugs
After meningitis, encephalitis, or other serious viral or
bacterial infections that may affect hearing
It is used in people with noisy working environment.
