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 LISTENING: Pediatric Speech Intelligibility (ages 3-6); Competing Sentences (ages 5 and up); Dichotic Consonant-Vowel (ages 5 and up); Dichotic Digits (ages 7 and up); Synthetic Sentence Identification-Contralateral Competing Message (ages 11 and up), ; Dichotic Sentence Identification (ages 11 and over)
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-Child Version (non-verbal stimuli for ages 6-9); Pitch Pattern Adult (non-verbal stimuli for ages 9-65); Duration Pattern Sequence (non-verbal stimuli for ages 11 and up)
MONAURAL LOW-REDUNDANCY: Pediatric Speech Intelligibility (ages 3-6); Selective Auditory Attention Test (ages 4-9); 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)
Auditec allows audiologists to design their own custom auditory processing disorder battery with any of the above tests. You can determine which tests will be used to examine based on your patient’s needs and age range. Once you have compiled a list of your test selections, email it along with your state/country to firstname.lastname@example.org for an exact quote with ordering instructions.
If you want to purchase a general battery that assesses all of the areas, consider the ACAP Battery. The ACAP Battery (CD115-9) includes Dichotic Digits, Duration Pattern Sequence, Dichotic Word Listening Test, Masking Level Difference-Tone, NU-6 Low Pass Filtered at 750 Hz, Time Compressed Sentence Test, Random Gap Detection Test, Selective Auditory Attention Test, and Competing Sentences.
Audiologists who regularly test non-English speaking patients often choose the NCAP Battery since all of the tests use non-verbal stimuli. The NCAP Battery (CD117-9) includes the Duration Pattern Sequence, Pitch Pattern Sequence – Adult & Child Versions, Random Gap Detection Test-Standard & Expanded Versions, and Masking Level Difference-Tone Version.
Audiologists with Spanish speaking patients often choose the Santiago APD Plus Battery. The Santiago APD Plus (CD120-9) includes Spanish Dichotic Digits, Spanish Filtered Speech, Spanish Binaural Fusion, Spanish Speech In Noise, Spanish Time Compressed Sentence Test, Spanish Staggered Spondaic Word, Spanish Dichotic Word Listening Test.
