The test is designed to be performed in the booth and complement your existing workflows while providing new information to the clinician.

ACT is available as a software upgrade depending on the age of your audiometer. You must have an audiometer compatible with the MedRx Studio Software. There is a license fee for ACT on some units.

Using the ACT Results

The ACT results can be used to help program a hearing aid in new ways. Unlike traditional speech in noise test the ACT is an aided speech in noise test which helps estimate the patient’s performance in noise with hearing aids. A normal ACT test would indicate that a patient can use noise reduction later and less aggressively than a patient with a severe ACT result.
