GB/T 5266-2006 Acoustics—Measurements of the longitudinal wave velocity and attenuation coefficient for underwater acoustical materials—Pulse tube method (English Version)
1 Scope
This standard specifies the method to measure complex reflection coefficient of sample of underwater acoustic materials under the condition of steady state plane wave with pulse sound technology and calculate longitudinal wave velocity and attenuation coefficient of the sample materials in rigid thick-walled acoustic tube.
This standard is applicable to uniform and compact polymer materials for underwater sound.
