This study focused on the problem of estimating hearing sensitivity in newborns from auditory brainstem responses (ABRs) evoked by clicks and 500 Hz and 4000 Hz tonebursts presented by a bone-conduction (BC) oscillator. The effects of acoustic energy transmitted to the ear canal, gender, and ear differences were also investigated. ABR thresholds for BC stimuli were 56, 52, and 53 dB (re 1 micro...

Human listeners can perceive speech signals in a voicemodulated ultrasonic carrier from a bone-conduction stimulator, even if the listeners are patients with sensorineural hearing loss. Considering this fact, we have developed a bone-conducted ultrasonic hearing aid (BCUHA). The purpose of this study was to assess the usefulness of the BCUHA in transmission of the emotional state of the speaker...

OBJECTIVE To compare and characterise abnormalities for short latency vestibular evoked myogenic potentials (VEMPs) elicited by air- (AC) and two differing types of bone-conducted (BC) stimuli during vestibular neuritis (VN). METHODS AC (500Hz short tone bursts) and two BC stimuli (500Hz at the forehead and impulses at the mastoids) were used to evoke cervical and ocular potentials (cVEMPs an...

low-intensity laser therapy (lilt) is defined to supply direct biostimulative light energy to the cells. while several studies have demonstrated that lilt has stimulating effects on bone cells and can accelerate the repair process of the bone, others reported delayed fracture healing or no effects after lilt. the aim of this article was to review the studies evaluating the biomodulation effects...
