Abstract

Influence of the temperatures, humidity and pressure on the ultrasonic wave absorption in considers. The values of absorption coefficient versus temperature from –500C to 1000C, humidity from 0 to 100% and pressure from 105Pa to 20*105Pa are calculated according to standard ISO 9613-1. The dependencies of the absorption coefficient cover a frequency range from 50 kHz to 1MHz. And the diagrams are presented in the logarithmic and linear scale.
