There are still many countries that did not develop their own noise calculation standards, especially in South East Asia.

SoundPLAN and SoundPLAN essential have over 50 standards to choose from so there will always be a standard that is accepted in your country.

SoundPLAN strives to implement all available noise calculation standards worldwide, so if there is any new legislation for noise calculations in your country, please let us know and we will implement it in SoundPLAN. Most local standards are derivatives from existing basic standards such as ISO9613.
