During the 2015 Decibel Ltd. carried out acoustic treatment of three of our conference halls. Before the implementation of the acoustic treatment in the premises the following results where measured regarding the reverberation time - 0,8/0,9/0,8 sec. After the installation of the acoustic panels the measured revereberation time has the following values 0,42/0,5/0,45 sec. The installation of the sound panels consistently improved the comfort in the halls. After the installation of the panels our halls meet the corresponding requirements regarding the sound parameters. Thank you for the promptness and quality of the service provided.
