Noise level map of the San Francisco Bay Area - live created by smartphones.

Participate (application ended)

Time frame: Mo. May 1 - We. May 18, 2017

The University of Geneva and Swissnex San Francisco is inviting citizens and visitors of San Francisco and the greater Bay Area to collect anonymous noise levels of their environment with our Android NoiseBay app. Results are made available here to the community and a reward of $200 will be awarded to one of the participants.

Noise can be harmful or simply be something you want to avoid at certain times. Our noise map indicates noise exposure in different areas to the community. Results can for example be used by individuals to create awareness about their noisy neighborhoods and for health studies. We are in particular interested in gathering noise levels in an efficient and load minimizing way for our participants.

Results will also be presented at our live demo at Pier 17 on May 18, 2017. All participants are most welcome to have a chat and drink at our event! Participants will receive an invitation via email.
