In Brief:
The effect of amplitude-, frequency-, and mixed-modulated stimuli on bone and air conduction auditory steady state responses (ASSRs) was investigated. Mixed-modulated stimuli with specific phase settings evoke larger bone and air conduction ASSRs compared with amplitude- and frequency-modulated stimuli alone, and the time taken to obtain these responses is reduced. Phase settings of 318° and 295° are predicted to evoke the largest responses for 1- and 2-kHz bone conduction ASSRs, respectively, and 292°, 300°, and 280° for 1-, 2-, and 4-kHz air conduction ASSRs, respectively. Implementation of these suggested that optimum settings will promote efficient collection of bone and air conduction ASSR data.
