Spectral Balance is based on a forthcoming joint standard from InfoComm and AES. It is envisioned to provide an industry-wide specification for sound system performance. Using multiple measurement techniques, including methods to minimize the effect of low frequency room modes, system performance is compared against a range of limits that are defined in the standard. If all of the frequency bands are within the limits, the sound system is said to pass, otherwise it will be marked as "Fail".
