Auditory steady-state responses (ASSR) allow objective assessment of auditory function using electroencephalography (EGG). If peripheral compression is, at least partially, due to cochlear compression, the amplitude of ASSR as a function of level can be assumed to reflect the compressive growth of the cochlear nonlinearity.

A recent study (Encina Llamas et al., ARO2014) showed, that compressive inputoutput functions with slopes similar to proposed compression ratios of cochlear level-growth functions can be found using ASSR obtained by stimulation with multiple sinusoidally-amplitude-modulated (SAM) tones. The goal of the current study is to investigate the estimation of cochlear compression using the same stimuli as used for ASSR (SAM tones).
