CityHush at EURONOISE 2012
... more!

You are invited to attend the session on acoustically green road vehicles and city areas and meet CityHush at the international conference EURONOISE, 10-12 June 2012 in Prague, Czech Republic.
At EURONOISE 2012 the CityHush session "Acoustically Green Road Vehicles and City Areas" (NS1) will be hold. Topics of presentations include definitions and impacts of quiet facades and quiet urban areas, noise of electric and combustion powered scooters, measuring and analyzing road traffic noise, noise mapping on a large scale and embedded parks in quiet zones. The session targets urban transport noise experts from industry and research. For registration and more information, visit

First CityHush Seminar!
Brussels, 23 November 2011 ... more!

On Wednesday 23 November, CityHush is organizing its first seminar in Brussels. Now that the project is halfway, partners will share intermediate results on Q-zones, noise score rating models, low-noise vehicles, low-noise road surfaces, and noise barriers. The seminar targets urban transport noise experts from the industry, research and public sector.

Test campaign in Athens for assessment of PTW annoyance ... more!

A test campaign in 4 different sites was developed in the city of Athens for an outdoor assessment of the annoyance of the people from road traffic, and specifically PTW (mopeds, scooters, motorbikes) traffic. The four sites were ranging an Leq between 50 and 80 dB (A), thus were representing a quiet area against very noisy area. In all cases pedestrians were interviewed, experiencing the annoyance of the passing by cars and motorbikes. A still unanswered question is if, when and why the PTW are considered more annoying than the cars. At a first look, by having asked about 200 pedestrians their opinion regarding the PTW (about 20 % of the vehicles pass-by in Athens roads are PTW), if the percentage of annoyed pedestrians by general road traffic leading to an Leq among 55 and 65 dB (A) is 71 %, 82 % is the percentage annoyed by scooters and motorbikes specifically.

Noise rating model for the outdoor environment ... more!

Current identification of hot spots in noise maps is based on façade levels and does not include possible beneficial effects of a nearby quiet outdoor environment. To enable an evaluation of noise in the outdoor environment, a noise rating model is developed in which indicators for outdoor noise are combined with information about the function of the area and the number of people making use of the area to predict the overall annoyance response. The model will be tested by investigating the effect of noise in the outdoor urban environment in subjects residing and walking in a realistic situation.

What is CityHush?

CityHush Acoustically Green Road Vehicles and CityAreas was a three-year research project co-funded by the European Commission, under the 7th Framework Programme. The activity should support European noise policy to eliminate harmful effects of noise exposure and decrease levels of transport noise creation, especially in urban areas, deriving solutions that would ensure compliance with the constraints of legislative limits.

A major objective is to provide municipalities with tools to establish noise maps and action plans (Directive 2002/49/EC) and to provide them with a broad range of validated technical solutions for the specific hot-spot problems they encounter in their specific city.
