WebApr 13, 2024 · The narrow-band CE-Chirp ® stimuli were delivered binaurally using headphones with intensities of 80, 60, 40, and 20 dB nHL (normal hearing level) at a rate of 90 Hz in ASSR. In ABR, the stimuli were delivered to the ears separately with the contralateral side, receiving 20 dB lower masking using the above-mentioned intensities. WebFeb 15, 2024 · The auditory brainstem response (ABR) is an evoked potential that originates at the auditory nerve (Cranial Nerve VIII). This test is used to assess the auditory system’s function from the cochlea through the brainstem. The response is identified by “peaks” that occur typically between 1 and 15 milliseconds from the stimulus onset.

WebWe explored the influence of stimulus polarity on the ABR from LS chirp compared to the ABR from click at 80 dBnHL in normal-hearing adults. Subjects and purpose: Nineteen adults with normal hearing participated. The ABRs were acquired using click and LS chirp stimuli using three stimulus polarities (rarefaction, condensation, and alternating ... WebAug 1, 2016 · ABR thresholds to air-conducted CE-Chirps were 9.8 dB nHL for neonates and adults. ABR thresholds to bone-conducted CE-Chirps were 3.8 and 13.8 dB nHL for neonates and adults, respectively. The difference in ABR thresholds to bone-conducted CE-Chirps was significantly different (p < .0001, η p 2 = .45).
