Table 1:
Medians, first (Q1) and third (Q3) quartiles, and number (N) of Onset times, A-, and B-durations calculated for each pressure sensor, at each exposure level. All times are shown (in ms) relative to the free-field (Field) sensor. FSurf: front surface; Surf: surface sensor adjacent to the ear; EAC: external auditory canal, adjacent to the tympanic membrane; SV: scala vestibuli; ST: scala tympani; ME: middle ear; std dev: standard deviation; N: number of included measurements.
