The problem
In the beautiful environment of the villa district Heide in Waasmunster, you’ll find the restaurant Vreedehof (EN: Peace Garden). For 20 years, this restaurant has been an established name among cyclists and hikers, who come to relax with a well-deserved beer or coffee. However, there is a downside to this popularity: the noise of the many customers in the dining room and the porches forced the owner to contact us for a solution. And rightly so: a reverberation time of 1 second was measured in the large hall, at the back porch an even higher reverberation time of 1,5 seconds was recorded.
