Yes, our patented algorithms filter out certain noises depending on the mode you choose. Everyday mode is designed to filter out constant “hums,” like a refrigerator running or an air conditioning unit blowing air. However, it will still pick up on important sounds like a person who starts talking to you, cars honking, and babies crying. Night mode is specifically designed to filter out snoring, while picking up on alarms, smoke detectors, and sirens.
