Spondee Binaural Fusion©

The Spondee Binaural Fusion© is an auditory processing disorder test for both children and adults using verbal stimuli. It is considered a binaural interaction test. It consists of selected child spondee words which have been band-pass filtered in two frequency bands: one for one channel (ear) and the other for the second channel. The low band extends from 500 to 700 Hz, the high band from 1.9 kHz to 2.1 kHz. The recording begins with pulsed speech spectrum noise, passed through the same filters for the purpose of establishing thresholds for those particular frequency bands. These thresholds are to be used to establish the proper presentation levels. Administration time is approximately four minutes.

The Spondee Binaural Fusion© includes: a) audio recording, and b) instructions and word list. The one-page instructions include administration, scoring, and interpretation information. Normative data is included, but it is not age-specific.
