Cirrus Research help Costa Rica combat traffic noise pollution

Leading noise monitoring specialists Cirrus Research have just completed a six-figure contract to supply the Costa Rican government with 50 of its Optimus Red sound level meters.


The large order of 50 Optimus Reds were recently shipped to the Central American country where they are going to be deployed by the Government’s Road Safety Council in a campaign to reduce traffic noise pollution in some of its most built-up cities such as the Capital, San Jose.

The Optimus Red kits had already been used by the Costa Rican police force and proved so popular among the officers for its user-friendly application and reading accuracy that the Road Safety Council followed suit. The project and the kits were even featured on the national news in Costa Rica as part of a story about how officers were trying to tackle traffic noise pollution on the streets.

The Cirrus R&D team were also able to modify the units so the sound level data could be printed out by officers on the spot to show to motorists who were breaking noise pollution levels with their vehicles and bikes.

Cirrus Export Sales Manager, Jonathan Phillips, said: “This was an interesting project to work on and the Optimus Red sound level meters were ideal for both the police and then the Road Safety Council initiatives.

“Costa Rica perhaps isn’t the first country you would think of to have a traffic noise problem but it is reassuring to see that governments globally are now taking this issue seriously and the health impact it can have on its citizens.”
