What is the acceptable noise level (ANL) test? The acceptable noise level (ANL) test is a method of determining how much noise the patient is able to tolerate whilst listening to a target signal/spea…
Note: FM transparency assumes that the hearing aid has already been programmed to match the target, according to the patient’s hearing loss. Launch Affinity/Callisto Suite and select the REM module…
How to determine if frequency lowering should be applied 1. Launch Affinity/Callisto Suite. 2. Ensure an audiogram is entered. 3. Navigate to REM module. 4. Fitting prescription setting will automati…
Introduction It can sometimes be difficult to understand feedback from your patient regarding how their hearing aid sounds. The Affinity Compact has a handy feature which allows you to listen directl…
What is the hearing aid transition (HAT) test? We understand you have new patients who attend with their existing hearing aid and sound preferences, but you do not have their historic fitting session…

What is the short increment sensitivity index (SISI) test? The short increment sensitivity index (SISI) test measures the ability to recognise 1dB increases in intensity during a series of bursts of…
What is high frequency audiometry? High frequency audiometry (above 8 kHz) is performed using the same procedure as normal air conduction audiometry. High frequency audiometry is helpful when testing…
What is Békésy audiometry? Békésy audiometry is an automatic method of measuring audiometric thresholds. It can be used for audiometric screening or in differentiation between the cause of the hearin…
What is speech audiometry? Most people acquiring hearing aids report trouble hearing speech, or more often trouble hearing speech in noise. Here speech testing becomes a strong test tool in the asses…
What is pure tone audiometry? Pure tone audiometry is a hearing test that establishes hearing sensitivity at various frequencies for air conduction and bone conduction. The test can specify the air c…
