Compact discs containing WAV files have been considered a superior way for audiologists to test patients for many years. That is because WAV files are high quality, but this file type has a drawback. Although it can be saved to computers, it tends to be too bulky to conveniently import to certain devices. That is why the general public quickly latched onto the MP3 file type. However, it has a drawback too. In order to make the file size smaller, the audio is actually compressed. Some in the audio industry believe the compression on MP3 file types compromises quality. That presents a big question for the audiology community: Would the quality of MP3 files produce different test results?
Recent research by Jennifer M. Brace and Robert W. Keith gives audiologists more confidence to use MP3 audio file types for testing. The study was based on twenty normal listeners using Auditec’s NU-6 Ordered by Difficulty Version II and found no significant difference between testing using a compact disc (WAV files) or MP3 files. This finding allows audiologists more freedom to test on their preferred devices.
Does this mean you should ditch your CD player or computer and trade it for an MP3 player? Maybe or maybe not. Since CDs are high quality and easy to use, it may be worthwhile for some audiologists to continue to use them. Other audiologists may need to travel and find smaller devices work best. Auditec permits customers to make one backup of purchased recordings for their own personal use. Customers now have a choice to make their backup as a WAV file or MP3.
Auditec’s test recordings vary from fully developed tests with a manual that includes age-specific normative data to simple test recordings without any normative data. Some audiologists have developed their own normative data for those test recordings. If that’s you, please consider sharing that information with us so that we can pass it onto other audiologists. Audiologists have voiced a real need for data on the following Auditec recordings:
- French Word Lists opposite Noise
- Modified Rhyme Test
- NU-6 opposite Noise
- NU-6 Time Compressed
- NUCHIPS opposite Noise
- PBK opposite Noise
- Spanish Word Lists opposite Noise
- Spanish Sentences opposite Noise
- W-22 opposite Noise
- W-22 Time Compressed
- WIPI Low Pass Filtered
- WIPI Time Compressed
Auditec is only interested in normative data that has been personally gathered by you or your organization. Please include the following information (if possible):
- number of normal subjects (No test size is too small.)
- ages of normal subjects
- regional background
- other applicable information
- your name or your organization’s name (so we can credit you)
We hope to gather this information from multiple sources to give audiologists a guideline to use for normative data. Please email this information to firstname.lastname@example.org. By working together, audiologists can improve diagnosis, treatment, and management for their patients. Thank you for your dedication to this field.

Researchers recommend hearing professionals use both verbal and nonverbal testing to evaluate patients. Nonverbal testing is especially useful when testing patients: 1) who do not use English as a first language, 2) who have language limitations due to hearing impairment, or 3) who use cochlear implants. Auditec offers a variety of nonverbal tests to suit the unique needs of hearing professionals around the world.
The Sound Effects Recognition Test (SERT) is a picture pointing test that uses sounds like a barking dog, whistling, or a vacuum. It includes instructions and normative data for ages 3-6 as well as the audio CD and the corresponding picture book.
Hearing professionals who are testing adults may find Environmental Sounds (also known as Forty Familiar Sounds) a beneficial test to add to their battery. This recording includes sounds like: bowling, roller coaster, and a babbling brook. A similar recording called Filtered Environmental Sounds includes those sounds at specified frequencies. These recordings can be employed as the hearing professional sees fit. No normative data or instructions are included; however, a sounds list is included.
Nonverbal tests play a key role in auditory processing. Auditec offers the Random Gap Detection Test, Gaps In Noise, Pitch Pattern Sequence, Duration Pattern Sequence, and Masking Level Difference-Tone Version to audiologists all over the world. Instructions and score forms (in English) are included with the audio CD purchase.
Minimizing the language barrier in auditory testing opens up a whole new world for hearing professionals to understand the limitations of hearing and processing of their patients. Nonverbal tests can be valuable tools to help hearing professionals identify hearing problems and diagnose disorders. Whether testing children or adults for either auditory discrimination or auditory processing, Auditec offers nonverbal tests for professionals with even difficult-to-test patients.
Children with attention deficits can be hard to diagnose. Is it attention deficit disorder (ADD)/ Attention Deficit Hyper Activity Disorder (ADHD) or is it an Auditory Processing Disorder (APD)? Or both? Auditec offers tools to help professionals correctly diagnose children so that appropriate steps can be taken to manage the attention deficit.
Many professionals still rely on solely on subjective information such as observations by parents and teachers to diagnose ADD/ADHD. However, there is an objective, quantifiable test to help diagnose (or rule out) ADD/ADHD as a cause of the child’s attention deficit. It is called the Auditory Continuous Performance Test (ACPT). This test is a recorded word list given in quiet (no background noise). The child listens and responds to a target word. It is a pass or fail test with normative data on ages 6-11.
The Selective Auditory Attention Test (SAAT) is an auditory figure ground test to help diagnose auditory processing disorders in children aged 4-9. It was developed to aid in the early identification of young children who have poor ability to attend (attention deficit), especially in noise. This test uses the recorded Word Intelligibility by Picture Identification word list: two lists in quiet and two lists in noise. (The competing message is an interesting story.)
Auditec provides established and reliable tests like the Auditory Continuous Performance Test and Selective Auditory Attention Test. With these tools, skilled professionals can confidently diagnose children with the correct disorder(s). Then recommendations can be customized according to the diagnosis to help the patient succeed in life. “Problem kids” become superheroes, and their skilled professionals do too!
