Ambient sounds for deep focus

Noiseloop is a free ambient sound mixer that helps you create a calm listening environment for focus, studying, reading, and deep work. Open it in your browser and build a mix without creating an account or installing an app. Layer 16 sounds, including rain, forest ambience, campfire, flowing water, ocean waves, and white, brown, or pink noise. Adjust each sound independently and use the master volume to control the whole mix. For a quick start, choose Noise Blocker, Deep Work, Relax, or Light Work, then browse the sound combinations within that mode. Use the built-in session timer for 25, 45, 60, or 90 minutes. A chime marks the end of your session, with optional browser notifications and a countdown in the browser tab. The simple, ad-free interface is designed for desktop and laptop work.

Problem it solves

Noiseloop helps people concentrate when background noise and nearby conversations make it hard to work, study, or read. It provides a steady background of ambient sounds that makes surrounding noise less distracting and helps people stay focused on what they are doing.

How it's different

Noiseloop is free, with no listening limits, ads, or sign-up. The interface is minimal and clutter-free. It delivers clean, seamless sound without distracting imperfections. A built-in timer removes the need for a separate app, and playback continues reliably when you switch tabs.

From the maker

I work in a noisy Yandex office 8h/day. Tried a bunch of ambient apps — all had crackling loops or paywalls. So I built the one I actually wanted to use. Hope it helps you too.
