Question

I need to purchase a new tympanometer and it has been a few years since I have looked for one. What is new in the area of immittance testing and what should I look for when choosing an immittance testing solution?

Answer

Jeanette Fitzke:  As far as immittance testing goes, there are no new tests and nothing has really changed in terms of testing over the past years – even Wideband is not yet recognized or widely used. However, there are improvements in the immittance testing process to make it more patient-focused and give more control to the clinicians. The ability to handle more patients requires an efficient workflow. One of the main disruptions in the testing process is the ability to get and keep a reliable seal. That is why a high-performing device and responsive probes can make a huge difference in helping you stay focused on your patients while streamlining the immittance testing process.

Diane Sabo:  When you think about it, the probe is one of the most important parts of the immittance testing process. The probe is what the clinician holds in his or her hand – it is the clinician’s tool – almost an extension of their hand and it touches the patient. Therefore, it is very important that to be effective, an immittance probe must be comfortable to hold, lightweight and responsive. The design of the probe is related to its performance – if it is difficult to hold and use then chances are that the performance of the probe and outcome of the test will be poor. When you are looking for a new tympanometer be sure to check if the probe or probes are lightweight, ergonomic and easy to use. The new MADSEN® Zodiac is an especially appealing alternative to traditional tymps as it was designed with focus on the probes and the way clinicians work when performing immitance testing.

Dawn Violetto:  From my perspective as a pediatric audiologist I need the device to be intuitive and fast.  Having controls on the probe itself are useful so that the clinician doesn’t have to leave the child’s side or stretch to reach a button.  In addition, when working with an infant’s ear, having a lightweight probe is especially important so that the probe is stable when in place and isn’t constantly falling out.

I was surprised just how easy it was to start using the new MADSEN® Zodiac. MADSEN Zodiac has three probes and each probe is designed for easier, faster and more stable placement. The diagnostic probes are exceptionally lightweight – and this ensures quicker sealing than regular, heavier probes. Light indicators tell you which ear you are testing and the status of the test. Audio feedback and the probe light indicators quickly alert you if you lose the seal. And the unique Dual Probe option enables you to keep the screening probe and the diagnostic probe connected at the same time. You can just grab the probe you need for a particular patient without interrupting your workflow. It has really made immittance testing easier for my staff and me.

When evaluating behavioral hearing thresholds in children it's imperative to maintain the patient's attention to stimuli. In-booth controls incorporating pediatric specific tools facilitate fast and accurate testing. The addition of a different narrow band noise (NBN), known as FREquency Specific Hearing assessment (FRESH), overcomes potential limitations of traditional NBN. NBN can underestimate thresholds at a given frequency due to wider filters. This learning module will review pediatric sound field testing guidelines, stimulus effects, and improved workflow with computerized audiometry.

  'It confirms my belief, initiated in graduate school, that speech recognition testing should be conducted with visual cues'   Read Reviews
Under natural conditions, listeners use both auditory and visual speech cues to extract meaning from speech signals produced by different talkers. However, traditional clinical tests of spoken word recognition routinely employ isolated words or sentences produced by a single talker in an auditory-only presentation format. We have developed new theoretically-motivated tests of audiovisual sentence recognition. Both the Multimodal Lexical Sentence Test for Adults™ (MLST-A™) The Multimodal Lexical Sentence Test for Children™ (MLST-C™) contain sentences with key words that are independently controlled for the lexical characteristics of word frequency (i.e., how often a word occurs in the language) and lexical density (i.e., the number of phonemically similar words, or neighbors, to the target word). To incorporate the kind of variability that listeners encounter in the real world, the sentences were drawn from stimuli produced by five male and five female talkers. The tests can be administered in a visual-only (V), auditory-only (A) or auditory-plus-visual (AV) presentation format. This presentation will describe test development and the psychometric properties of the tests including list equivalency, test-retest reliability and validity. Performance data will be presented for three different groups of adult and child participants: persons with normal hearing, persons with hearing loss who use cochlear implants, and persons with hearing loss who use a hearing aid. The clinical availability of this testing using the Madsen Astera2 by GN Otometrics will be discussed.
