Any modern otolaryngology office has to be set up with special equipment, tools, and ENT instruments. To conduct examinations, as well as correctly diagnose hearing problems, diseases, and ailments, a doctor cannot do without a set of specialized devices. Each of them should be selected with great care and responsibility.
A tympanometer is actively used in otolaryngology. This acoustic and electronic device helps to accurately measure the hearing acuity. The principle of its operation resembles a sound generator, based on a psychophysical test. In other words, the device helps to analyze the physiological sensations in response to sound waves fluctuations. An otolaryngologist adjusts the sound amplitude and frequency and examines the human hearing organs’ condition, utilizing a tympanometer. In the process of this screening, the ability to perceive different sound pitch, loudness, tone, and distinctness level can be determined. This instrument is one of the main measuring devices for any otolaryngologist. Using it, a specialist can diagnose diseases that manifest themselves with symptoms of hearing problems of various degrees.
Medical equipment and instruments manufacturers offer different types of tympanometers. The main classification feature, according to which models are differentiated, is the type of signal utilized. In this regard, you can come across such varieties of tympanometers as: Speech. Hearing acuity assessment is based on speech intelligibility or audibility threshold. Tone. Hearing capabilities, in this case, are assessed by pure or sinusoidal tones audibility threshold. Combined. The devices combine the functions of both speech and tonal models. The devices provide hearing acuity measurements in decibels. As a basic reference standard, the average statistical information on the healthy person’s hearing threshold is used. The data on the degree of severe hearing loss, obtained in the course of diagnostic procedures, directly depends on the deviation from the average statistical data. To obtain accurate results and carry out quick diagnostic procedures, we recommend choosing electronic automatic devices. It is better to focus on modifications in which the operating parameters can be adjustable and possess the convenient interface. The device should be highly sensitive to facilitate diagnosing abnormalities and hearing disorders in the early stages.
We recommend paying attention to devices, which are characterized by the following set of functions and features:
The prices of some systems can be as low as 900 USD or less, while the newest, high-tier systems may cost as much as 3.500 USD. The manufacturer plays a crucial role in making up the tympanometer price. The more famous the brand the more expensive the machine, as the brand name itself says a lot about the quality and longevity. AMPLIVOX,Welch Allyn,,MAICO,AMPLIVOX are considered to be the most well-known. Besides, one should understand that new and demo machines will cost more than refurbished or used tympanometers. What is the difference? New machines have never been used. They have the manufacturer’s warranty. Demo machines are, as a rule, exhibition models. They have not been used in clinical practice but they have been often presented at exhibitions. As a result, the price is lower. Refurbished machines are used machines that have undergone improvements (refurbishment can be done at the manufacturer’s facilities or in private repair shops)
