Filter by:Speech intelligibility in noise will be evaluated in adults with moderate to moderate-severe sensorineural hearing loss using a Phonak Roger microphone and hearing aid with compatible Phonak Roger receiver. Target speech will be presented from multiple directions while competing diffuse background noise is presented simultaneously. Participants will repeat back words and percent correct is calculated.
The ACHIEVE Hearing Intervention Follow-Up study is a randomized trial of a telehealth versus conventional clinic-based hearing healthcare (HHC) delivery model among older adults who are existing hearing aid users to determine if a telehealth HHC model improves hearing aid use and other communication outcomes compared to clinic-based HHC.
Research supports that bimodal stimulation includes improvements in auditory performance and daily living over using a cochlear implant (CI) or hearing aid (HA) alone. Although bimodal users continue to achieve high levels of satisfaction, speech perception in noise continues to be highly problematic. The aim of this field study is to identify which directionality schemes in a bimodal solution are preferred by users using an ecological momentary assessment tool.
A phase 2 trial with LY3056480 in patients with stable SNHL
Hearing-impaired children are at risk for a vestibular impairment, as the auditory and vestibular end organs are closely related. Although this can compromise a child's development on many levels, vestibular testing is not routinely performed in this vulnerable group. This project aims to give each congenitally hearing-impaired child in Flanders (Belgium) access to a basic vestibular screening at a young age and set an example for other regions worldwide.
A single centre, open, comparative, parallel group, prospective clinical investigation with a single 10 year follow up visit.
ESolutions functions for children and young people with the myPhonak app is a prospective study to investigate whether the myPhonak app can improve speech understanding in children with hearing aids. The study is linked to randomized patient and test allocation carried out.
Background: The Eustachian Tube (ET) is a mucosa-lined connection between the nasopharynx and the middle ear cavity. It is believed to have three functions: 1) ventilation of and pressure equalization in the middle ear cavity, 2) mucus drainage from the middle ear, and 3) protection against sound and infection from the nasopharynx1. In adults, Eustachian Tube Dysfunction (ETD) can cause complaints from one or both ears. For many years, various definitions of ETD have been used, impairing the opportunity to compare studies. However, in 2015, an international consensus on definition, types, clinical presentation, and diagnosis of ETD was published by Schilder et al2, which has been adopted by all the Scandinavian countries. The symptoms include pressure (fullness), and/or pain in the ear, muffled hearing, and overall discomfort. Furthermore, chronic ETD can result in tympanic membrane retraction, atelectasis of the middle ear cavity, and ultimately formation of cholesteatoma3. Unfortunately, the symptoms of ETD are multiple and inaccurate giving rise to varying estimates of the prevalence. As an example, a study in UK found a 0.9 % prevalence of ETD4. In addition, clear guidelines on diagnostics and treatment are not currently available due to the fact, that no objective test for detection of ETD exists. In the need of a symptom scoring system, the patient reported Eustachian Tube Dysfunction Questionnaire (ETDQ-7) has been developed and validated in English5. Yet, translation into other languages as well as validation in other settings are necessary in order to substantiate the applicability of ETDQ-7. ETD is associated with a lack of opening of ET. It is believed that the length, diameter and angle of ET influences its ability to open regularly, thus affecting its function. A short, narrow and angled ET may predispose to ETD. However, the imaging available to visualize ET are not accurate enough to diagnose ETD. A direct test of the function of ET is not available. Tubomanometry is a relatively new method developed to directly test the opening of ET, but is yet to be validated6. Both non-surgical and surgical treatment options to improve the function of the Eustachian Tube are available. Non-surgical management includes pressure equalization methods (e.g. the Valsalva maneuver), antihistamines, treatment with decongestants, and nasal douching with a saline solution. Surgically, ventilation tubes are often used to treat ETD. In case of adenoid hypertrophy obstructing the pharyngeal opening of ET, adenoidectomy is recommended. Balloon Eustachian Tuboplasty (BET) was introduced in 2010 by Ockermann et al7. BET is a non-invasive procedure performed under general anesthesia. During the procedure, a catheter is inserted either endonasally or transtympanic into ET, and a balloon is inflated with water for approximately two minutes. Various heterogeneous studies have shown a short-term effect of BET, but long-term effects are unclear8. In summary, despite the assumption of being a common condition, the field of ETD suffers from lack of precise definition, diagnostic criteria, identification of underlying causes as well as purposeful treatment, and prognostic factors. Especially, long-term effects of BET need further investigation. Therefore, in an effort to fill out the gap of knowledge about ETD, the following specific aims are proposed:
Listeners will conduct sound quality ratings of recordings talkers in a moving car processed using three different microphone processing strategies: an investigational adaptive directional microphone, an omnidirectional microphone and a fixed directional microphone. Participants will listen to the recordings streamed via commercially-available and individually-prescribed hearing aids, and conduct ratings onsite in the lab. The procedure will involve a training session and within-subject repeated measures. Stimuli will be randomized.
