Definitions

  • the upper end of the target dynamic range is predefined by determining a boundary comfort level of the listener. Should the 90 th percentile estimator be above the boundary comfort level, the gain is decreased slowly. The 30 th and 90 th percentile estimators are thus of use in determining how well the output dynamic range matches the target dynamic range.
  • An increase in MOL and comfort level will usually be acceptable due to the increased ability of the listener to handle loud noise in the presence of substantial ambient noise.
  • An increase in the audibility target parameter maintains the target dynamic range above the ambient noise, even as the ambient noise increases. Above a second threshold, further increases in the target dynamic range parameters are not permitted' even widi further increases in ambient noise, to prevent hearing damage to the listener by the output sound signal.
