Abstract:
Chirp-evoked auditory brainstem responses (ABRs) have shown a better performance compared to click-evoked ABRs, due to their temporal organization which compensates for the traveling wave delay achieving a synchronous discharge of the cochlea. In this paper we present the development and evaluation, in healthy subjects, of a series of notched noise embedded frequency specific chirps to evoke ABRs. Results of the ABRs using Phase Synchronization Stability are also reported. The assessment of frequency specific responses by using noise embedded chirps was possible, and the PSS analysis supported previous findings which stated that low frequency channels are better for the recognition and analysis of chirp-evoked ABRs. Accordingly, future analysis can be done to make a faster recognition of frequency specific chirps-evoked ABRs.

The Cochlea
Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
