Unlike conventional noise apps that emit a generic sound regardless of your environment, Shush pioneers a unique approach by intelligently analyzing your room's specific frequency signature. It then precisely removes those existing tones from its output, ensuring a complete broadband spectrum at a fraction of the volume, thereby protecting your crucial REM sleep. This innovative technology is exclusive to Shush. Key features include a smart sleep timer, a specialized tinnitus notch filter for relief, and real-time sound synthesis that guarantees a non-looping, seamlessly consistent audio experience.
