For the city stadium in Ostrava-Vítkovice, we modernized the power sound system of the main grandstand, because the audience had been struggling with poor intelligibility of the reports.
- We used loudspeakers and cable routes that meet the fire standards for the evacuation radio in order to incorporate the new system.
- When submitting the work done, we made an acoustic measurement of both the sound pressure level and the speech clarity parameter, and both of these values came out with a sufficient reserve above the required values.
- The powerful sound system is based on the principle of the distribution sounding of the grandstands and speakers are installed in clusters of two to ensure even sounding throughout the grandstand height.
