Auditory Processing Disorder Testing

It is recommended that audiologists use established, reliable tests with both verbal and non-verbal stimuli that assess different auditory processes. Auditory Processing Disorder Tests are often broken down into four categories. The categories are 1) DICHOTIC LISTENING for binaural integration and separation, 2) TEMPORAL PROCESSING for auditory pattern temporal ordering-APTO and temporal resolution), 3) MONAURAL LOW-REDUNDANCY (monaural separation closure-MSC), and 4) BINAURAL INTERACTION. Auditec sells tests for each of these categories.

DICHOTIC LISTENINGPediatric Speech Intelligibility (ages 3-6); Competing Sentences (ages 5 and up); Dichotic Digits (ages 7 and up); Synthetic Sentence Identification-Contralateral Competing Message (ages 11 and up)

TEMPORAL TESTS: Random Gap Detection Test (non-verbal stimuli for ages 5 and up); Gaps In Noise (non-verbal stimuli for ages 7 and up); Pitch Pattern (non-verbal stimuli for ages 8 and up); Duration Pattern Sequence (non-verbal stimuli for ages 11 and up)

MONAURAL LOW-REDUNDANCY: Pediatric Speech Intelligibility (ages 3-6); Time Compressed Sentence Test (ages 6 and up); Time Compressed Word Lists (ages 11 and up); Low Pass Filtered Tests (ages 11 and up); Synthetic Sentence Identification – Ipsilateral Competing Message (ages 11 and up)

BINAURAL INTERACTION: Spondee Binaural Fusion (appropriate for children and adults); Rapid Alternating Speech (appropriate for children and adults); Masking Level Difference (appropriate for children and adults)

A release from masking is expected in the latter section.

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. Available from Auditec, Inc.  Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order. FREE shipping to contiguous US.
