A02YYUW Temperature Compensation

The speed of sound varies over the specified operation temperature range by +- 6%. Since there is no temperature compensation in the A02YYUW, the accuracy is also at least +- 6%.
I would like to calculate a temperature correction in line with my temperature measurement. For that I need to know the speed of sound that A02YYUW is using internally to calculate:
distance = speed * lapsed time.

Does anybody know this internally-used constant value for the speed of sound?
Thank you in advance.

348 m/s is the speed of sound at an air temperatur of 28°C. So I will use it in summer ;-)
