According to ISO the accuracy of the calculated pure-tone attenuation coefficients for atmospheric absorption is estimated using the following table:. Leap seconds Leap seconds are used to provide a link between the extremely stable time scale based on atomic clocks and the more variable time scale of ido solar day. The faster, easier way to work with standards. Below we’ve highlighted some of our sectors. The calculator presented here computes the attenuation coefficient according to ISOgiven those four variables.
