The Traffic Noise, without the pollution

Traffic noise is considered as a nuisance, and possibly one of the most difficult sources of noise to avoid in many places around the world. One way of reducing the annoyances of traffic noise is to mask it using more pleasant sounds - such as our rain and stream noises - or even this traffic noise!

If you can't beat your enemies, join them

When the frequency characteristics of the masking noise differ too much from the noise you are willing to camouflage, higher masking levels will be needed to cover the nuisance. When the masking levels become too loud for comfortable use, we suggest trying a strategy inspired from a well-know proverb: if you can't beat your enemies, join them!

In our case, this strategy consists of using one traffic noise to mask another. Of course, the masking traffic noise must be carefully designed such as to offer a better alternative to the original nuisance. Instead of using a simple traffic recording, we use re-synthesis to create an artificial traffic noise, which sounds like static - think of a waterfall - yet retains the important characteristics of the original sound. By sharing the same acoustic properties as the nuisance, our masking signal now achieves higher efficiency and can be used at quieter levels than any other masking sound. And because of the particular nature of our masking noise, even when the nuisance spikes above the mask, it will still be camouflaged.

Try listening to our traffic noise for a quarter of an hour, and see if your brain slowly learns how to filter it out from your conscious perception. In most cases, it will do so after a couple of minutes. Then, you will realize that not only has the masking noise been wiped from your perception, the unwanted noise has as well.

Calibrated Output

This sound generator is calibrated and outputs a pink-like spectrum when the sliders are horizontally aligned. Calibration is unique to this website, and can be used to compensate for your own hearing, audio equipment, and listening environment deficiencies: follow our Calibration Procedure once, then access Your Hearing Curve from the right pane.

  This one reminds me of when a storm just landed in the area and the trees are swaying erratically against the wind. I kind of like it.

  I enjoy being out and about and this gives me that feeling. Thank you, Stephane!

  This sounds like traffic as heard from afar; it's quite smooth and slips into my subconcious almost instantly. I close my eyes and I can envision myself while working in my imaginary penthouse office, with the wonderfull skyline of a futuristic city out of my window.

  This is really amazing. My family moved to a quiet place and I seem to be the only one who actually enjoys and misses the sound of city traffic. Helps to block out unnecessary thoughts and focus.

  I have had pretty severe anxiety problems for most of this year. Honestly, the rhythmic noise of traffic is very therapeutic. It reminds me of where I grew up.

  Highway rest stop after a long drive...let the drone of traffic lull you to sleep.

  This goes very well with all of the songs by Daughter. It's like they were made for each other.

  When my brother is playing violin, and life is just plain hectic, it's nice to know that I can escape my house and go to the big city to get some work done!

  I moved to Ohio for high school, and lived down the road from HW18. The sound of the cars on the road was the soundtrack to the nights I sat in bed replaying the events that took part that day. It reminds me of when I was kid, when all there was to worry about were broken hearts and bad grades. Thank you for putting this up.

  Damn, it is amazing!

  As much as people seem to hate these kinds of noises, they actually relax me as they remind me of drives out to vacation spots, seeing the sights of the cities.

  As I grew up near a motorway, using the traffic noise in this way makes me feel calmer, more at home; on more windy nights, my room would end up sounds pretty much exactly like this, and it would lull me to sleep.

Each slider controls a particular frequency band, from the lowest to the highest frequency. Adjust sliders to taste.

To mask undesirable noises, focus on bands sharing the same tone as the noise you want to cover. Doing so achieves a higher efficiency, and quieter masking noise levels.
