At ARK, we take pride in achieving the results beyond our customers’ expectations for all the projects that we do. For every project, upon completion, detailed acoustical testing (FFT Analysis) is conducted in presence of the customer, and we prove – in each and every case – how we have exceeded our own promises made before beginning the project.
