Whether you are in a hospital, school, or private practice setting, NOW is the time to start APD testing. You have time to review the materials and be ready for your clients when people get back to their daily lives. A popular question around here is “What APD battery should I buy?” If you are just starting out, I would recommend one of the following:
The APD Battery (Item CD170-9) is ideal for communities that have non-English speakers or areas with multiple cultural accents because all of the tests are nonverbal. It includes the Gaps In Noise (GIN), Random Gap Detection Test (RGDT), Pitch Pattern Sequence-Musiek Version, Duration Pattern Sequence-Musiek Version, and Masking Level Difference-Tones. Each test has its own instructions with normative data for various ages. The APD Battery costs $329.75 US funds plus shipping (free shipping in the US).
The MAPA-2 Battery (Item CD179-9) is another popular choice. This battery includes a mix of verbal and nonverbal recordings. It is comprised of monaural, temporal, and binaural testing. A testing manual is provided with interpretation for ages 7-14. The MAPA-2 Battery costs $215.00 US funds plus shipping (free shipping in the US).
The SCAN-3 Battery is also widely used in the audiology community. It can be used as a screening test or diagnostic tool. This battery also consists of both verbal and nonverbal recordings. The SCAN-3 Child Version (Item CD121-9) includes a manual and normative data for ages 5-12. It costs $350.60 US funds. The SCAN-3 Adult & Adolescent Version (Item CD122-9) includes a manual and interpretation for ages 13-60. This version also costs $350.60 US funds plus shipping (free shipping in the US).
Many factors can affect your choice of APD Batteries such as language, age group, and budget. Whether you choose the APD Battery, MAPA-2, SCAN-3, or decide to build a custom APD Battery from the large variety in our catalog, Auditec is here to supply your needs with fast friendly service.
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? 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.
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.
