Masking Level Difference-Speech©

The Masking Level Difference-Speech© is an auditory processing disorder test. It is considered a binaural interaction test sensitive to low brainstem. This recording employs spondee words imbedded in speech spectrum noise bursts.  It is in two sections; section 1 is where both the noise and the spondees are in phase, section 2 is where the noise is in phase and the spondees are 180 degrees out of phase. A release from masking is expected in the latter section.

The Masking Level Difference-Speech© includes a) audio recording, and b) instructions and score form as printable pdf files. The one-page instructions contain administration, scoring, and interpretation information. Normative data is included, but it is not age-specific.
