Audible Contrast Threshold (ACT)

ACT™ (Audible Contrast Threshold) is a revolutionary test designed to improve speech understanding in noisy environments for hearing aid users. It measures speech-in-noise performance and aids audiologists in personalizing hearing aid settings, particularly adaptive features, to enhance speech intelligibility in noise.

The Audible Contrast Threshold (ACT) test assesses a person’s ability to perceive speech in noisy environments. It measures hearing quality rather than volume, unlike traditional audiograms. The test lasts about 2 minutes and can be performed using standard audiometric equipment like Affinity Compact.
