Detecting hearing loss in the absence of any known organic disorders poses a challenge for audiologists. Compared with behavioral tests, electrophysiological and electroacoustic methods are considered to be more up to date and reliable for detecting false and exagerrated hearing loss (FEHL). Auditory steady state response (ASSR) test can be used to detect FEHL considering the advantages of speed and accuracy of the method. However, very little is known about using ASSR to detect FEHL and this study aims to present our clinical experiences regarding to ASSR and FEHL. We hypothesized that the differences between the behavioral pure tone thresholds (BPTT) and ASSR thresholds will be larger for subjects with FEHL than subjects with organic hearing loss (OHL) and there will be a stronger agreement between BPTT and ASSR thresholds in subjects with OHL. Differences between ASSR thresholds and BPTT were greater for FEHL group than OHL group and correlation coefficients for each frequency were weaker in FEHL group. Agreements and differences among the ASSR and BPTT values should be used to evaluate the reliability of the audiological assessment of FEHL.
