Prague 5 Installs Online Acoustic Sensor to Monitor Noise at Smíchovská Náplavka

Prague’s riverbank hangouts are some of the Czech capital’s most popular destinations during the summer months, with thousands of locals and visitors cooling by the Vltava for live outdoor concerts and other events.


But for residents that live in areas the surrounding Náplavka by Prague 2 and Smíchovská Náplavka across the river in Prague 5, the late-night noise levels emanating from these hotspots can become a headache.

City codes specify that all outdoor music concerts must end by 22:00, and that noise levels must not exceed a certain amount – exactly 87 decibels. But many feel the enforcement of these codes has been inconsistent.

This year, however, Prague 5 isn’t messing around.

In advance of the second edition of the popular Kapitánská party sponsored by Captain Morgan’s, which is expected to bring over 10,000 visitors to Smíchovská Náplavka on June 13, Prague 5 mayor Pavel Richter has issued an open letter.

In it, Richter reminds organizers of the city codes – and unveils a new device that will be monitoring upcoming events.

“This year, for the first time, City of Prague 5 will use an Acoustic Sensor during the party, which will allow you to monitor the noise levels online,” Richter states. As per the recommendation of experts, the sensor has been placed at the corner of Vltavska and Hořejšího nábřeží.

The acoustic sensor is available to the public and accessible here.

It’s already giving readings. The online meter isn’t exactly live, but updates every 5 minutes with a sound level measurement.

As of writing (Friday morning), the area has maintained a consistent reading over the past few hours of between 41 and 42 decibels, which might be a baseline noise level for the area minus any activity.

Should it exceed 87 decibels during the live music events, the city will take action on an individual basis, though it’s unclear exactly what penalties organizers will face.

Over in Prague 2, residents have been pushing for similar measures to be implemented. So far, however, the city has yet to implement them.
