The wideband acoustic reflex (WAR) procedure with clicks as probe signals has been proposed to address certain limitations of the currently applied clinical acoustic reflex (AR) test. This study compared the WAR test with both 226- and 1000-Hz AR tests using five tonal and broadband noise activators. Results showed that WAR thresholds were substantially lower than 226- and 1000-Hz AR thresholds and the differences were statistically significant. WAR threshold testing proves to have great potential in clinical application.
