Latency and Amplitude Effects of Electrode Placement on the Early Auditory Evoked Response
TL;DR: This study examined the effects of electrode placement on the early auditory evoked response in normally hearing subjects and found that three combinations of electrodes gave the largest Wave V amplitudes.

Early/middle evoked potentials to tone bursts in quiet, white noise and notched noise.
Randall C. Beattie,Robyn L. Boyd +1 more
TL;DR: It was concluded that frequency specificity can be improved when tone bursts are mixed with notched noise or white noise, and white noise is preferred, however, because it can be implemented with less complex instrumentation and calibration than notches noise.

Relationship between pure-tone and speech loudness discomfort levels among hearing-impaired subjects
Randall C. Beattie,Robyn L. Boyd +1 more
TL;DR: It was concluded that pure-tone LDLs are not accurate predictors of the speech LDL, and, if the clinician wants to ascertain the upper intensity for listening to speech, this measurement must be made directly.

Effects of click duration on the latency of the early evoked response
Randall C. Beattie,Robyn L. Boyd +1 more
TL;DR: The effect of click duration on the latency of waves I, III, and V was investigated by testing 20 normal-hearing subjects at 60 dB HL using electric pulses of 25, 50, 100, 200, and 400 microseconds and found the 100 microseconds duration is preferred to the 25-microseconds pulse because the latter reduced the maximum measurable hearing loss.
