Audiometers

Audiometers or tympanometers as they are often referred to, are medical devices that are used in the diagnostic examination of hearing, less often they are also referred to as otoacoustic emission devices (OAE machine). Specifically, diagnostic audiometers are applied in the differential diagnosis of hearing loss, in the diagnosis of auditory neuropathy and give full control of the intensity and frequency of hearing, making the measurement process easy, fast, and comfortable.

Like all diagnostic tests, the tympanogram is performed with special audiometers, both in adults and especially in infants and children, with this test the mobility of the tympanic membrane is measured. Also, the degree of pressure in the middle ear is determined, as the control of the function of the Eustachian tube, the evaluation of the integrity and elasticity of the auditory chain. Also, diagnostic audiometers help to study the neuromuscular reflexes and especially the abductor muscle, essential diagnostic tests for infants, and the early diagnosis of diseases.

Also, through the screening audiometers, the election examination is done to diagnose the degree and type of hearing loss. The patient is initially placed in a soundproof chamber, wears headphones, and listens to sounds at various frequencies and intensities. He confirms that he heard each sound individually by pressing a previously assigned button. In this way, audiometry devices achieve a recording of the quality of hearing through air conduction, i.e. the transfer of sound through the air through the ear canal and eardrum so that it ends up in the hearing organ, as it happens normally. Then, through the clinical audiometers, the patient responds positively to the sounds they hear through a small vibrator placed behind the flap. By vibrating the bone behind the ear, the sound is transmitted directly to the hearing organ (bone conduction).

As for the tympanometers, during the examination a special plug is placed in the examined ear and a specific sound stimulus is administered. The tympanometer records the volume of the ear cavity as well as the way the tympanic membrane pulsates. Useful conclusions are drawn for the presence of fluid in the ear, holes in the eardrum, and other anatomical lesions of the hearing device.

In medi-shop.gr you can find a wide variety of diagnostic audiometers (or tympanometers) of the latest technology, with silent keys, easy-to-use operation, accurate measurements, designed to provide top performance and reliability in diagnostic applications.
