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)

cUSTOMAuditec 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 auditecinfo@auditec.com for an exact quote with ordering instructions.

You can receive several popular tests at a discounted price by selecting the APD Battery. The APD Battery (CD170-9) includes Gaps In Noise (GIN), Random Gap Detection Test-Standard (RGDT), Pitch (Frequency) Pattern Sequence – Musiek Version, Duration Pattern Sequence – Musiek Version, and Masking Level Difference-Tones.

I hope this information is helpful to you as you determine which auditory processing tests are right for you for your patients.

Therapy in Action

The power to help your patients is within reach. If your patient has a specific ear deficit on dichotic listening tasks, consider the Constraint-Induced Auditory Training Program (CIAT). It is appropriate therapy for children with dyslexia, persons with hypersensitivity to noise, adults with aphasia, or anyone who would like to improve their listening ability. The most common question we get about this training program is: what would this therapy look like inside my organization?

One of the greatest advantages to CIAT therapy is the enormous selection of materials. Twelve compact discs of recorded material is included in the standard version. Another benefit of the CIAT is the included manual on CD-Rom. It provides a wealth of information like an overview, background, case studies, exercises and worksheets. The only equipment you need is a CD player and stereo headphones. You might begin by asking your patient (or patient’s parents) to commit to two 30-minute sessions for six weeks. You can be flexible and slow down the program or accelerate the program to suit the patient’s needs.

Therapy begins with over two CDs with exercises like dichotic digits, dichotic consonant-vowels, dichotic letters, and dichotic sentences. The patient will listen and respond as the therapist scores. After the exercises are complete, the patient moves onto short stories in noise and then a much longer story in noise. The stories are a listening task with no set exercise or scoring, but the therapist may ask occasional questions about what is happening in the story to make sure the listener is engaged.  Auditec now  includes a complimentary backup of the longer story (discs 5-12) with every purchase of the CIAT – Standard and Longer Story versions. This backup allows professionals to loan this portion of the CIAT to their patients for self-administration at home.

Auditec has received positive feedback about the use of this program. Their patients are experiencing improvement thanks to their caring audiologists. Will your patients be next?

Speech Discrimination for Children

For speech discrimination testing in adults, audiologists often choose either the W-22 or NU-6. If they want to shorten the testing time, they will use a list that is ordered by difficulty or a short interval recording. However, the choice between word recognition tests becomes more complicated when it comes to children because there are several to choose from. I am often asked: Which test is best? There is not one clear answer because the best test depends on the age range of your patients.

If your patients’ age range is 12 and older, you can confidently administer the adult word lists such as the W-22 Form A or NU-6 Form A. Depending on the vocabulary of the child, you may choose to administer these lists to kids a little younger than 12. The administrator must start the recording, then the patient simply repeats the word he or she hears it on the recording.

The PBK-50 Form A word list was designed for lower grade school age children. The PBK is similar to the W-22 or NU-6 word list except the vocabulary is more appropriate for this younger age group. Again, the patient simply repeats the word as he or she hears on the recording.

WIPI 2

The Word Intelligibility by Picture Identification (WIPI) fits a lower age range of 5 to 8 year olds. This test makes use of a picture book (sample at left). The child listens to the recording, then points to the pictured representation of the word as he or she hears it. There are six choices on each page. Aside from being easier for younger children, it is also beneficial for the test administrator to see the selection by using picture-pointing since the child may be difficult to understand.

image005The Northwestern University-Children’s Perception of Speech (NU-CHIPS) test reaches an even younger age range. Ages 2-5 can also be tested by administering this picture-pointing test. As you can see from the pictures at right, there are less choices for the younger child to select from as they listen to the recording.

The test an audiologist administers to a child should be appropriate for his or her age group (or language age). If the test is too easy or too hard, the test results may not show his or her true ability to discriminate speech. Therefore, it may be necessary to purchase one or more tests for your patients depending on the patient age range. You have been entrusted to evaluate the hearing of these amazing kids so it is up to you to utilize the best and most appropriate tests available.

Audiology Equipment Advice

Occasionally, Auditec receives questions about purchasing audiology equipment. Does Auditec sell equipment? What CD player should I buy? Will your CDs work with my audiometer? What equipment do you recommend? fb VU Meter Info web page Auditec does not sell any equipment and does not endorse any brand. This affords us the opportunity to offer some unbiased advice on buying equipment.

To start, consider how your equipment can satisfy your specific needs. Ask yourself some questions to evaluate your needs. How much physical space do I have for my equipment? What is my budget? Will I need portable equipment? What is the age range of my patients?

Auditec compact discs play in all CD players and everywhere else you can play standard audio CDs (like computers). CD players sound pretty much the same no matter how expensive they are so you can save a few dollars by purchasing a relatively inexpensive CD player. Since CDs can degrade when you leave them in the player, we do not recommend buying a multi-disc changer. If you may need to test in other locations, you may consider purchasing a portable CD player. (This article was edited on March 23, 2017 to include recent research by Jennifer M. Brace and Robert W. Keith.) Recent research has concluded normal listeners tested using the mp3 audio files of speech discrimination tests produce the same valid results as when tested using the wav audio files on compact discs.

There are a variety of audiometers on the market. Regardless of what brand you choose, make sure you purchase a two-channel audiometer. Even some of the most basic Auditec recordings have different information recorded to the left and right channels. For instance, a word list may be recorded to the left channel while noise is recorded to the right. If you want to use the word list in quiet, you could use your left channel only. If you want to mix it with noise, you would use your left and right channels. Be sure your equipment is set up properly from the very start. If possible, spend some time getting to know your audiometer dealer and hold onto his or her contact information in case you have questions in the future.

Some of the best audiologists are not skilled in technology use. If that’s you, make sure the audiometer you select is easy to operate. Some audiometers come with speech already loaded on them. Unfortunately, we have heard some horror stories about the quality and clarity of these pre-loaded recordings. Make certain that your audiometer does not limit your test selection so that you can improve, expand, and update your test library in the future.

If you plan to accept pediatric patients, it may be useful to have a computer in the testing room. Some tests for young children (like NU-CHIPs) include pictures as pdf files so patients can view the pictures on their computers. Some Auditec customers have reported that the use of a computer engages children better than the use of a book. However, convenience or a lack of space may cause you to prefer simply purchase a classic NU-CHIPs picture book or use the picture CD-Rom to print the pictures and put them in a three-ring binder.

Ultimately, the evaluation of your specific needs and preferences should shape your decisions about the best audiology equipment for you. Whether you are just starting out or considering a change, Auditec wishes you the very best luck as you shop for audiology equipment that is appropriate and easy to use.

Next, Auditec sold auditory test materials on cassette tapes. Believe it or not, we still get requests for this discontinued format. At one point in time, Auditec even made its recordings available on digital audio tapes (DATs).

cUSTOM

Now, Auditec provides quality audio recordings on compact discs. Customers can combine multiple recordings to one disc and play it using their CD player or computer.

MP3s are a convenient next step for professionals who want to use portable equipment that does not take up a lot of space like iPods, iPads, and MP3 players. (This article was edited on March 23, 2017 to include recent research by Jennifer M. Brace and Robert W. Keith.) Recent research has concluded normal listeners tested using the mp3 audio files of speech discrimination tests produce the same valid results as when tested using the wav audio files on compact discs.
