Question

Can I perform verification of hearing aid fittings and validation in FF using my Trumpet system?

Answer

The verification of hearing aid fittings is conducted to ensure that their gain and output are correct. Each hearing instrument programming can only be verified employing REMs, adjusting the sound measurements just in front of the tympanic membrane via the REM probe measurement tube, using validated prescriptive targets displayed via a probe microphone system, matching the output to these targets using a calibrated LTASS input signal (e.g. ISTS) delivered at soft, medium and loud levels.

The validation of the verification process is also paramount to ensure that the end user obtains what they wanted or required, not just in terms of addressing audibility and intelligibility but also in terms of their perception of loudness. The validation part varies but it should also include accurately assessing the patient’s individual psychoacoustics and hearing aid needs.

Inventis Trumpet is an advanced Real Ear Measurement system but also a Diagnostic Audiometer. The best combination unit in terms of portability, convenience and size. Size (WxDxH): 15.5 x 10 x 24.5 cm; Weight: 1.5 kg / 3.5 lb; Weigh - wireless probes: 50 g / 0.11 lb. (see Figure 1).

Controlled through Maestro software interface (see Figure 2), it is easy to do verification and then validation running QUICKSIN via free field using the Trumpet built-in amplified speaker.

This seminar will cover the scientific principles behind probe microphone measurements as applied in hearing clinics. We will briefly discuss the theory and go through how the PMM are performed in the clinic. The course is designed for audiologists seeing adult patients for hearing device prescription. Basic knowledge of PMM will be helpful.

The introduction of modern tools assessing otolith and ampullary reflexes in the high-frequency domain (VEMPs and video-HIT, respectively) has enabled a fast functional analysis of all inner ear receptors, offering new interpretations for end-organs and afferents abnormalities detected in patients with cochleo-vestibular pathologies. The literature review highlights how vestibular disorders could result in specific lesion patterns, including selective dysfunctions involving a single receptor. A series of patients with isolated impairment of a semicircular canal at the video-HIT will be presented and discussed. Each selective canal dysfunction will be correlated to the remaining clinical-instrumental data and related inner ear pathology. The underlying hypothetical pathomechanism accounting for each single scenario will be provided, with the help of pertinent bibliographic support.

Over the past five years, we have seen a growing interest in studying vestibular disorders in children. The most commonly noteworthy are vestibular disorders in congenital sensorineural hearing loss (SNHL) and cochlear implants. Identifying and diagnosing vestibular and balance dysfunction in children is essential for their overall well-being. However, the diagnosis process is very demanding.This talk will provide an overview of vestibular and balance assessments in children with SNHL.

Vestibular disorders in children are a significant cause of childhood morbidity with various manifestations that are often unrecognized or undiagnosed. The etiological profile, phenotype, and management for peripheral and central disorders are markedly different from that in adults. The diagnostic algorithm with the latest technology is also different as children are far more difficult to obtain anamnesis from and to test as compared to adults. Examining a child is really an art that can come from years of experience and knowledge about the pediatric vestibular system and its development. It is also important to recognize the close overlap with pediatric neurology and indeed, a robust knowledge in neurology is essential to practice pediatric neurotology. This presentation includes an overview of the developing pediatric vestibular system in children, the etiology of pediatric vestibular disorders, the diagnostic process with evidence-based latest methods, and their management. The differences in pediatric vestibular diagnosis and disease profiles are also highlighted from the authors’ personal series.
