SmartEP system (Intelligent Hearing System, Miami, FL, USA) was used with two stimuli: click stimulus and tone burst
Threshold prediction using the auditory steady-state response and the tone burst
auditory brain stem response: A within-subject comparison.
A avaliacao audiologica constou de: emissoes otoacusticas evocadas por estimulo transiente (EOAT), supressao das emissoes otoacusticas, audiometria com reforco visual (realizada a partir dos seis meses de idade) e ludica (realizada a partir dos dois anos de idade), medidas de imitancia acustica e potencial evocado auditivo de tronco encefalico (PEATE) por estimulos clique e tone burst
. Os procedimentos utilizados variaram em funcao da faixa etaria e foram realizados em ambas as orelhas em todos os casos (Figuras 1 a 3).
Gray Measure with Muted Tone Burst
, for example, is a stunning relief, in which a long, feltlike panel abuts a two-foot-square gray-on-white painting that here occupied a corner of the gallery.
The ultrasonic tone burst
(harmonic wave with the finite length) is excited on one of the boundaries of the specimen in terms of stress and the evoked boundary oscillations are recorded on both boundaries in terms of displacement or particles velocity.
500Hz tone burst
stimulus was selected based on the earlier studies which show a better amplitude and response rate with 500Hz tone burst
The test signal was 5-cycle tone burst
, modulated by Hanning window.
The lower portion (Panel B) illustrates the waveform of a 0.24 kHz tone burst
while the upper panel shows the response of an auditory nerve fiber to repeated presentations of that stimulus.
The first technique is to repeatedly hit the same spot on the surface using a tone burst
generation and then to tune the interferometric receiver for a narrower range of frequencies.
Neonatal subjects reared for 4 weeks with a moderately intense 2 kHz sound exposure stimulus, then probed with a 90 min 2 kHz tone burst
, and exhibited a significant increase in the number of c-fos-labeled neurons over the entire region of interest studied, including in the 2 kHz tonotopic band.
We recorded cVEMP using an air-conducted stimulus with a 500-Hz tone burst
