Here is a very interesting article from Mr. Paul Holloway, P. Eng.,  published in the CINDE journal and dealing withStructural UT: Variables Affecting Attenuation and Review of the 2 dB per Inch Model

The North American standards for welded steel construction, CSA W59[1] and AWS D1.1[2], use an approximation for ultrasonic attenuation of 2dB/in. This approximation is based on the use of large, low frequency transducers which are not always well-suited to the wide range of weld thicknesses and geometries used in the codes. This paper documents computer simulations and experimental results performed to gauge the suitability of this linear factor to approximate a non-linear  phenomenon. Additionally, models of smaller transducers and higher frequencies are included to study their effect. This is performed to determine how alternate criteria and procedures may be developed to retain the same levels of sensitivity but expand the range of transducers beyond that currently permitted.”
