    What is the formula to calculate acoustic absorption in water? particularly sound in the ultrasonic range.

    Hi there
    welcome to PF

    doesn't matter what frequency

    attenuation is proportional to the freq 2

    there's dozens of hits on google when ultrasonic sound absorption in water is typed in

    time for you to go do some reading :smile:

    cheers

    thanks dave

    i understand that Attenuation is the gradual decrease/dissipation of Acoustical energy whereas Absorption is the acoustical energy being takenup by the medium; in this case, acoustical energy is converted to heat.

    Like u said attenuation has a proportional relationship to the frequency. However, there is not really a standard Absorption formula or absorption coefficient.If there was I probably, havent found it or unable to comprehend. From what i found; at different frequencies, the absorption coefficient varies. Correct me if i'm wrong.

    not whereas ..... attenuation is the result of absorption ( and dispersion) :smile:
