Comprehensive Review of the Madsen Midimate 622: The Ultimate Compact Audiometer for Clinical and Diagnostic Use
The Madsen Midimate 622 is a clinical/diagnostic audiometer that stands out for its simplicity and efficiency, offering a range of functionalities in a compact design that surpasses many audiometers twice its size. Its portable structure makes it ideal for both in-office use and off-site testing.
The Midimate is perfect for routine hearing tests, featuring four special tests, internal memory, NOAH compatibility, and the capability to print audiograms externally. Additionally, it allows up to five pre-programmed test procedures to be loaded in advance and activated with the simple press of a button. This provides quick and efficient operation, adapting to the needs of various testing environments.
Equipped with comprehensive facilities for patient communication and monitoring, the Midimate is ideal for installation in sound rooms and for conducting speech audiometry. Weighing 3.9 kg, including a hard case, the audiometer is portable enough for external testing, offering flexibility and convenience for audiology professionals.
The Midimate's intuitive design facilitates quick learning and usage. It offers air and bone conduction, contralateral masking with narrow band noise (N.B.N.), and speech noise. Additionally, the audiometer includes specialized tests such as S.I.S.I., Fowler, Rainville, and Stenger, meeting a wide range of diagnostic needs.
Professionals can program up to five custom test settings, making the Midimate highly adaptable to different clinical protocols. Results can be printed via an external printer or the Zodiac 901, ensuring patient data is documented accurately and professionally.
The Madsen Midimate 622 audiometer is designed with modern connectivity in mind, ensuring seamless integration into today’s computerized office environments. The serial data interface on the Midimate 622 can be connected to either an external printer or a PC. When connected to a PC with NOAH, the optional Audi-Link™ program allows for the direct transfer of audiometric data from the Midimate to NOAH’s audiometry screen and patient database. This capability enables test information to be stored directly in the NOAH database and allows audiograms to be displayed on-screen in real time.
Moreover, when the Midimate is connected to a desktop printer or the Zodiac 901 Middle-Ear Analyzer, you can print out audiograms directly without the need for a PC. This feature adds a layer of flexibility and convenience, making it easy to produce hard copies of test results on the spot. The Midimate’s compatibility with PCs ensures that it remains up-to-date with evolving technology, safeguarding it from obsolescence.
The Midimate 622 is equipped with an alphanumeric transflective LCD display with backlighting, measuring 155 x 16 mm. This high-quality display ensures clear visibility of test parameters and results, enhancing the user experience and facilitating efficient operation in various lighting conditions.
The Madsen Midimate 622 audiometer features two separate channels: one dedicated to stimulus and the other to masking. This dual-channel setup allows for precise control over the testing environment, ensuring accurate and reliable results. By separating the stimulus and masking functions, audiologists can perform more sophisticated and nuanced assessments, catering to a wide range of diagnostic needs.
The Midimate 622 offers versatile output options, enhancing its adaptability to various testing scenarios. It supports standard headphones, bone conduction transducers, insert earphones, and can be connected to a free-field loudspeaker via an external amplifier. This range of outputs allows audiologists to conduct comprehensive audiometric evaluations in different settings, from individual ear testing to broader free-field assessments.
The Midimate 622 provides a variety of tone stimuli, including pure tones, pulsed tones, and warble tones. This flexibility in stimulus options helps in tailoring the testing procedures to the specific needs of each patient. The frequency range for air conduction and free-field testing spans from 125 to 8,000 Hz, while for bone conduction, it covers 250 to 6,000 Hz. This wide frequency range ensures that the Midimate can accurately assess hearing across the spectrum, from low to high frequencies, providing a thorough evaluation of auditory function.
