Noisli is a background noise generator.
It's a supremely simple idea: a web app* that plays high-quality sounds that help you work, relax or sleep.
It looks like this:
Just click on the little icon and listen.
Does a downpour outside your window help you get all droopy-eyed and lazy-limbed? Or perhaps the distant rumbling of thunder clouds? Wind whistling across desolate moors? The busy-body tweeting of a bird-filled forest? The cosy cracking of a warm fire? There's even a bustling coffee shop (this one makes me feel a little strung out though!).
You can double sound up too - or even play all sounds simultaneously (an interesting experiment if a little anxiety-inducing).
Personally, I prefer silence when I work, but I really do like this little guy's elegant and efficient design.
