TI  - The phase angle of addition in temporal masking for diotic and dichotic listening 
      conditions.
PG  - 247-59
AB  - The phase angle, alpha, between a tonal signal and a tonal masker was varied from 
      0 degrees to 135 degrees in simultaneous masking, forward masking, and 
      pulsation-threshold paradigms. In all conditions the frequency of the signal and 
      masker was 500 Hz. For forward masking both diotic (MOSO) and dichotic (MOS pi) 
      listening conditions were investigated. Only the dichotic case was studied using 
      the pulsation threshold method. In simultaneous masking, thresholds varied as a 
      function of alpha in both diotic and dichotic conditions. Thresholds in the 
      diotic conditions were consistently different from those in the dichotic 
      conditions -- i.e., there were masking-level differences (MLDs) at most values of 
      alpha tested. In forward masking and pulsation-threshold, however, thresholds 
      were independent of alpha in the dichotic conditions; and thresholds were 
      independent of alpha in the diotic, forward masking conditions. Nevertheless, for 
      forward masking the dichotic thresholds remained below the diotic thresholds, 
      yielding MLDs of 3-6 dB. Thus, in nonsimultaneous masking, there is a clear 
      effect of the interaural signal phase, but not of the masker-signal phase 
      relationship, on signal detectability. These results imply that masker-signal 
      phase information is either not preserved or not used by subjects in 
      nonsimultaneous tone-on-tone masking experiments.
