Clarity of voice communication is critical. Noise reduction technology, trained through Artificial Intelligence (AI) machine-learning, is integrated into the radio devices to suppress loud background noise and improve the clarity of calls — so workers on the apron and taxiway, for example, can hear and be heard clearly. Ground operation workers often work in teams. Using multiple radios in close proximity to one another can sometimes cause acoustic feedback such as howling and distortion, which compromises radio communications. The AI-trained noise suppression automatically adjusts the audio profile of the receiving radio to minimise the impact of acoustic feedback.
