Auditory Processing Disorder Testing

November 12, 2015May 14, 2018 ~ auditecinfo ~ Leave a comment

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 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)

Dichotic Digits-Musiek©

September 29, 2015December 30, 2022 ~ auditecinfo ~ 3 Comments

The Dichotic Digits test is an auditory processing disorder test for ages 7 and up using verbal stimuli. It is considered a dichotic test for binaural integration sensitive to brainstem, cortical, and corpus callosal lesions.

Dichotic Digits – Musiek© is a test by Dr. Frank Musiek. This version is similar to the Dichotic Digits standard version. That is, digits from one to ten are presented dichotically. One set is single pair; the second is double pair. Usually, the single pair set is for practice. Dichotic Digits-Musiek version includes the digit “seven.” In contrast, the standard version does not include the digit “seven” since it is a two syllable word in contrast to the other nine digits. The Musiek version includes age-specific normative data on double digits for ages 7 and up. The standard version includes normative data on double digits for ages 11 and up.

Is the Musiek version or standard version better? Neither version is considered better. Both versions are popular and widely used. Decisions are mainly based on which version the audiologist was originally trained in or by personal preference. Due to the similarities between the standard and Musiek versions, it is usually unnecessary to purchase both versions.

Dichotic Digits-Musiek© includes a) audio recording, and b) instructions and score form as printable pdf files. The two-page instructions consist of administration, scoring, and interpretation information. It includes age-specific normative data on double digits for ages 7 and up.

Pediatric Speech Intelligibility©

September 29, 2015December 30, 2022 ~ auditecinfo ~ 5 Comments

The Pediatric Speech Intelligibility Test© is a test for children ages 3 to 6. It fits in two important auditory processing domains. It can be categorized as both a dichotic test and a monaural low-redundancy speech test (monaural separation closure-MSC) sensitive to low brainstem.

The importance of speech audiometry, especially where the test materials include both monosyllabic words and sentences, has been well established for adults. Experience with performance vs. intensity (PI) functions and message to competition ratio (MCR) functions with adults led to the development of an analogous test for children; the Pediatric Speech Intelligibility (PSI) test.

The PSI includes both monosyllabic words and and two sets of sentences recorded in quiet and with competition (auditory figure ground). The test employs color plates with pictures of animals (animals were used to avoid ethnic biases) which represent either the sentences or the words. It is an extremely useful tool for the investigation of peripheral and auditory processing with children down to a language age of three or slightly younger.

The test includes: a) corresponding laminated color plates, b) audio test recording, and c) manual and score forms as printable pdf files. This extensive manual includes background, administration, and interpretation information including normative data for young children.

The Competing Sentences© is popular with both psychologists and audiologists. It is an auditory processing disorder test and is considered a dichotic sentence test for binaural separation sensitive to neuromaturation and language processing. It uses verbal stimuli and is appropriate for ages 5 and older. It consists of 30 pairs of sentences with similar subject matter within each sentence pair. These sentences were recorded so that each pair begins and ends simultaneously. Administration time is approximately 7 minutes.

Competing Sentences© includes: a) audio recording, and b) instructions and sentence list. The two-page instructions encompass format, procedure, and interpretation. Normative data for ages 5, 6, 7, 8, 9, and 10. At age 10, normal scores are 100% in both ears so it can be assumed that normal patients over age 10 would achieve similar results.

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.
