Filter by:The goal of this descriptive study is to collect the wideband immittance data in Thai normal hearing and conductive hearing loss adults. The main questions it aims to answer are: 1. What is normative data of wideband acoustic immittance in Thai normal hearing adults 2. What is the wideband acoustic immittance data in Thai conductive hearing loss who have type A, AS and Ad tympanogram Participants will examine hearing tests consequently - pure tone audiometry - Tympanometry with ipsilateral acoustic reflex - Wideband acoustic immittance
Tinnitus - defined as ringing, humming, or other sounds in the ears or head - is a very common problem for Veterans. Hearing aids that deliver low-level amplification are being used by audiologists to help people with tinnitus who also have normal hearing. However, there is a lack of research evidence showing that this practice is effective. Despite this fact, the practice clearly is spreading. Reports from audiologists in the field as well as research presentations refer to hearing aids being used in this way. Use of hearing aids has been shown to reduce distress from tinnitus for people with hearing loss. Additionally, the use of external sound to help reduce the impact of tinnitus has been shown to be effective. There is clearly a gap in the research regarding the use of hearing aids as a therapeutic method to manage tinnitus when hearing is considered normal. This study will obtain pilot data evaluating people with normal hearing and bothersome tinnitus to find out whether low-level amplification through hearing aids may provide benefit.
An EEG study using continuous speech stimuli to assess neural language processing in a hearing impaired population. Participants listen to short radio excerpts in different Signal to Noise Ratios (SNR) and answer comprehension questions as well as listening effort questions. We assess the effect of different algorithms on neural language processing as well as subjective listening effort. Each participant hears 12 randomized segments of speech (about 4min long each) with different settings on their hearing aid (reference condition, noise reduction algorithm, beam forming algorithm). This will be a controlled, single blinded and randomized active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa.
The present cross-sectional study aims to examine the cognitive capabilities of older adults, aged 50 to 89, with normal hearing or age-related hearing loss by means of the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals (RBANS-H). Secondly, the correlations between cognition on the one hand and hearing and speech reception capabilities on the other hand are investigated. For this purpose, twenty participants are included in the age categories 50 to 59, 60 to 69, 70 to 79 and 80 to 89, bringing the total number to 80. Three questionnaires are administered to the participants: the Health Utilities Index-2/3 (HUI 2/3), Dizziness Handicap Inventory (DHI) and a general questionnaire on education and profession, medical history, hearing aid use and tinnitus. Also an audiological examination is performed, including pure tone audiometry, speech in quiet and speech in noise audiometry. Finally, cognition is assessed using the RBANS-H.
This study is designed to pilot an intervention technique to reduce the self-stimulating behaviors seen in individuals with autism spectrum disorders using intervention with ProFoveate pellets. Self-stimulating behaviors like hand flapping, eye blinking, and rocking, can interfere with the individual's ability to interact with their peers. Participants will wear the pellets for four week and measures with taken again. Another group of participants will not get the pellets. Both groups will be tested at the beginning and end of the study. Any variations in self-stimulating behaviors will be documented through parent report, Observational data. The investigators hypothesize that they will see changes in self- stimulating behaviors as a result of the strategic placement of the ProFoveate™ pellets on the ears of one group of the participants.
