It is generally agreed that masking sound must be applied with precision and consistency in order to be predictably effective and comfortable. The ability to do so has increased significantly in recent years as sound masking technology has evolved. The existing standard is too lenient with respect to measurement requirements and needs to be revised to ensure that the current expectations of system specifiers are being met. Furthermore, with the understanding that masking is used throughout office environments, the inclusion of some guidelines for closed offices should be considered.
