Page 28 1 Introduction Important information on ultrasonic testing The ultrasonic wave is attenuated in any material. This sound attenuation is very low, e.g. in parts made of fine- grained steel, likewise in many small parts made of oth- er materials. However, if the sound wave travels larger distances through the material, a high cumulative sound attenuation can result, even with small attenuation coef- ficients.
