Same Sky's SPL calculator allows the user to convert a speaker's specified SPL on the datasheet to different real-world conditions, or to compare sound pressure levels between two devices with different specified parameters on their respective datasheets. To use the calculator, enter the specified SPL level, rated power and measured distance from the Same Sky datasheet into the "Spec / Original SPL" fields. In the "Equivalent SPL" fields, enter the desired distance and power and the converted SPL value will be provided.
