Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application - 2019_20

2019-07-18 10:31:06 | BioPortfolio


A methodical evaluation of novel sound changing principles in CE-labelled Sonova brand hearing instruments (e.g. Phonak hearing instruments) is intended to be conducted on hearing impaired participants. These sound changing principles are enabled by respective hearing instrument technologies and hearing instrument algorithms. The aim of the study is to investigate and asses strength and weaknesses of these novel sound changing principles in terms of hearing performance to determine their application in hearing instruments (Phase of development). Both, objective laboratory measurements as well as subjective evaluations in real life environment will be carried out. This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarter based in Stäfa

Efficacy of Digital Noise Reduction Strategies: A Hearing Aid Trial

The purpose of this study is to see if noise reduction programs in digital hearing aids help patients hear better than hearing aids without these programs. We also want to know if we can ...

Hearing Loss Prevention for Veterans

Hearing loss is the most prevalent service-connected disability in the VA. It causes communication difficulties, which contribute to isolation, frustration and depression. A major cause of...

Predicting Success With Hearing Aids

The primary complaint of individuals with hearing loss is difficulty understanding speech in the presence of background noise. Although hearing aids help individuals understand speech in b...

Risk Factors for Hearing Loss as a Result of Exposure to Noise During Military Training in the IDF

As part of the proposed work, the investigators would like to examine whether there is a need to use a training video to train IDF combat soldiers to improve the use of ear plugs and to pr...

The Performance-Perceptual Test as a Counseling Tool

The purpose of the study is to determine whether a new test of ability to understand speech in noise and an associated counseling program can improve hearing aid satisfaction. Participants...

Effects of Directional Microphone and Noise Reduction on Subcortical and Cortical Auditory-Evoked Potentials in Older Listeners With Hearing Loss.

Understanding how signal processing influences neural activity in the brain with hearing loss is relevant to the design and evaluation of features intended to alleviate speech-in-noise deficits faced ...

What is noise-induced hearing loss?

Noise-induced hearing loss is sensory deafness caused by long-term exposure of the auditory system to a noisy environment. Auditory fatigue is an early symptom of noise-induced hearing loss, and heari...

Hearing in Noise With Unilateral Versus Bilateral Bone Conduction Hearing Aids in Adults With Pseudo-conductive Hearing Loss.

The role of bilateral bone conduction amplification in patients with bilateral conductive hearing loss is unclear because cranial attenuation is usually considered negligible, and both cochleae can be...

Health Literacy and Self-Reported Hearing Aid Use in the Health and Retirement Study.

Understanding the determinants of hearing aid use is important to improve the provision of hearing healthcare. Prior research has indicated that materials in the clinic and online, as well as audiolog...

Improving Sensitivity of the Digits-In-Noise Test Using Antiphasic Stimuli.

The digits-in-noise test (DIN) has become increasingly popular as a consumer-based method to screen for hearing loss. Current versions of all DINs either test ears monaurally or present identical stim...

Medical and Biotech [MESH] Definitions

Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.

Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)

Professionals skilled at diagnostic testing of hearing, HEARING IMPAIRMENT, and CORRECTION OF HEARING IMPAIRMENT by non-medical or non-surgical means.

Procedures for correcting HEARING DISORDERS.

Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
