STI simulation tools persist because fixing underperforming PA systems is costly
Evidence
STI methods are well established, and in some countries the STI values for sound systems in public spaces are regulated. Furthermore, the standard that describes sound systems for emergency purposes ISO 7240-19 (2007) defines the minimum STI value to be 0.5. Public announcement systems for public spaces are costly, and if the STI of a new building is measured to be lower than that targeted in the design process, the acoustic and electrical changes that must be made may be expensive. This is one reason why STI simulations and measurement systems are of great importance. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2393
