Today almost all room acoustic calculations are based on the Sabine formula. Even though it is known that you often get different values when you compare calculations with actual measurements in a room. Therefore, Ecophon has developed a calculator in which the intention is to have more accurate acoustic values before measurements. The Ecophon Acoustic Calculator is

Well-designed studio monitors are engineered to reproduce an input signal with extreme fidelity, maintaining near-flat frequency and phase response at all levels up to the threshold of clipping. However, the performance of any monitor will be influenced by the acoustics of the space in which they operate. Difficult room acoustics, even with proper speaker placement,
