Performing Stenger Test with Piccolo Audiometer and Maestro Software I would like to perform a Stenger Test with my Piccolo audiometer. I don't see the Stenger option in the Maestro software toolbar. What steps should I take?
Why are SII and Percentile indispensable in your fitting software? The Speech Intelligibility Index (SII) gauges the portion of a speech signal audible to a listener. It serves as a valuable tool during hearing aid fittings, providing patients with insights into the availability of speech with or without aids. Additionally, it helps assess whether the aids offer an appropriate level of audibility, prompting adjustments if needed. SII, a percentage between 0% and 100%, correlates with speech intelligibility. For example, an SII score of 25% suggests roughly half of the speech is intelligible, while 80% predicts most of it will be.
Are there specific steps and diagnostic measures for identifying early signs of vertigo? Vertigo serves as a symptom rather than a definitive diagnosis, making it imperative to consult a healthcare professional for an accurate determination of its root cause[1].
A clinical case for explaining how much important is to perform simultaneous horizontal binocular VHIT A 47-year-old woman comes to my office complaining of the appearance of a set of symptoms for a few months. The most relevant were the following: double vision, blurred vision, oscillopsia, visual delay, difficulty following moving objects, instability with eye or head movements (particularly in horizontal gaze). At the onset she went to an ophthalmologist, but the evaluation carried out did not reveal any pathological elements. Looking at the report I immediately realized that an important element had been omitted: the evaluation of extrinsic ocular motility.
Pre-Test Instructions for VNG Examination To ensure a successful examination, it is crucial to provide the patient with the following instructions in advance:
Understanding the "TEN Test" and Its Compatibility with Inventis Audiometers The "TEN Test" (Threshold Equalizing Noise) was developed to identify dead regions in the cochlea, specifically targeting the inner hair cells (for additional information, refer to Brian Moore's 2004 Ear and Hearing). Recognizing these regions proves valuable in both selecting cochlear implant candidates and appropriately fitting hearing aids.
Comparison between vHIT Remote Camera and vHIT Head Mounted There are two types of tools for recording vHIT: one with a remote camera and one with an accelerometer head mounted.
Why is the anatomy and physiology of vestibular receptors so important for the vHIT? The cupula-endolymphatic system can be described through the physical model of the pendulum with critical damping, (i.e., the cupula after deflection quickly returns to the neutral position without overshooting) of which three constituent elements are represented by:
Basic parameters and interpretation of vHIT The vHIT consists of the selective analysis of each of the six semicircular canals through head impulse stimuli realized at high velocity ≥ 200°/sec for the horizontal canals and ≥ 150°/sec for the vertical canals. Some elements are fundamental for a correct outcome and interpretation of the exam:
How can I determine the most suitable Prescriptive Fitting Algorithm for my patients? Prescriptive fitting algorithms are pivotal in the hearing device fitting process, aiding professionals in setting the initial device configuration, which should then be refined in collaboration with the patient. Most such algorithms require, at minimum, an assessment of air conduction hearing thresholds and frequency-specific amplification needs, while considering patient-specific variables like bone conduction thresholds, discomfort levels, gender, age, and earmold type.
