Noisli - Background Noise Generator and Ambient Sounds for Focus, Sleep and Relaxation | WarmIndex

Noisli is a background noise generator and ambient sounds app that allows users to mix high-quality sounds for focus, sleep, and relaxation.

🚀 Overview

Noisli is a web and mobile platform that enables users to create custom ambient soundscapes by mixing sounds like rain, ocean waves, white noise, forest, coffee shop, and more. It helps mask distracting background noises from traffic, offices, or neighbors, providing a consistent auditory environment that reduces stress, improves concentration, and aids sleep.

The project solves the common problem of noise pollution in modern life, which disrupts productivity and well-being. It's built for remote workers, students, professionals in open-plan offices, commuters, and anyone seeking relaxation or better sleep.

Created by designer Stefano Merlo and developed by Noisli Labs UG in Berlin since around 2013, Noisli was built to bring calm and focus to a noisy world, serving over a million users worldwide.
