Abstract

The test box can be used for fitting hearing aids (verifying audibility for the individual), for setting and fine-tuning specific signal processing (e.g., directional microphones, noise reduction, frequency lowering, telecoil responses), and for setting the response for specific accessories (e.g., remote microphones). If you have selected these features for your patient, it is important to make sure they are working properly and turned on. In addition, these tests can help you address specific patient complaints. Let us start by using the test box to pre-set a hearing aid and then we will move on to speech tests of signal processing and features.
