This paper focuses on transducers, which are the most important components of bone conduction implants. To improve vibration magnitude, we develop a coil transducer in driver mass loading is reduced by about 3.25-fold compared to magnet transducers. We use finite element analysis derive and implement maximum Lorentz force frequency characteristics. compare effect magnitude that an older transdu...

introduction: in order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. one of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...

Bone Conduction Hearing aids are used mainly for the treatment of patients who suffer from Single Sided deafness and/or Conductive/ mixed hearing loss but not Bilateral Sensorineural loss. Vibration Acoustic Stimulation is a combination both air and bone conduction at same time, four aids, two ears bilateral one aid, on defective ear single sided (SSD) Unilateral Loss. We have tried this approa...

OBJECTIVES Five databases were mined to examine distributions of air-bone gaps obtained by automated and manual audiometry. Differences in distribution characteristics were examined for evidence of influences unrelated to the audibility of test signals. DESIGN The databases provided air- and bone-conduction thresholds that permitted examination of air-bone gap distributions that were free of ...

BACKGROUND Little research exists to demonstrate efficacy and verification measures of the Baha system versus traditional bone-conduction hearing aids. This study gives statistical data about 10 children who have used traditional bone-conduction hearing aids, Baha coupled to a Softband, and the Baha system implanted. PURPOSE The purpose of this study was to compare functional gain at 500, 100...

OBJECTIVE The aim of these experiments was to investigate procedures used when estimating bone-conduction thresholds in infants. The objectives were: (i) to investigate the variability in force applied using two common bone-oscillator coupling methods and to determine whether coupling method affects threshold estimation, (ii) to examine effects of bone-oscillator placement on bone-conduction AS...

Computer-based audiometry allows for novel applications, including remote testing and automation, that may improve the accessibility and efficiency of hearing assessment in various clinical and occupational health settings. This study describes the validity of computer-based, diagnostic air and forehead bone conduction audiometry when compared wtih conventional industry standard audiometry in a...

We investigated the speech intelligibility differences of normal and bone-conduction stereo headphones of target speech localized at 45◦ on the horizontal plane when competing noise is present. This was our effort to study the possible effect of crosstalk found in bone-conduction headphones on speech intelligibility. All sound sources were localized on the horizontal plane. Target speech was lo...

OBJECTIVES/HYPOTHESIS To prospectively evaluate hearing outcomes in children with otosclerosis undergoing primary stapes surgery. STUDY DESIGN A nonrandomized, nonblinded, prospective case series. METHODS Thirty-four consecutive pediatric patients who underwent 41 primary stapedotomies for otosclerosis in a tertiary referral center were included. Patients were included when there was eviden...
