The Fan Noise Generator app generates custom fan noise that’s perfect for sleeping at night. Fan Noise Generator will simulate the sound of your existing box fan or oscillating fan by allowing users to change the fan motor speed, oscillation, and volume. The simple and modern interface remembers all settings for quick fan noise generation. The Fan Noise Generator app is based on our most popular box fan sound, but adds speed and oscillation controls to make the sound completely unique. The Fan Noise Generator app is great for travel as you won’t need to bring a bulky fan with you, but it’s also perfect for home-use as it sounds completely realistic. The Fan Noise Generator running on a mobile device doesn’t consume as much power as using a mechanical fan so you'll save money on your electricity bill. New: Cross-device syncing and presets — Sign in to sync your favorite settings across all your devices and save up to 10 custom presets for instant access to your perfect fan sounds anytime, anywhere.
