The experimental data have been analyzed by including the universal critical relaxation part Ψ_1(ε,ω), on the basis of Kawasaki's mode-mode coupling theory, and non-universal background relaxation part Ψ_2(ε,ω). As a result, the total sound absorption Ψ(ε,ω) can be written as the sum of three terms, Ψ(ε,ω)=Ψ_1(ε,ω)+Ψ_2(ε,ω)+σ(T), where e is a reduced temperature, ε=(T_c-T)/T_C, and σ(T) is a classical contribution. At high frequency (ω>1), the behavior of the sound absorption is quite different from the case of liquid-gas phase transition that is observed in Xe. In particular, the Kawasaki prediction, which is confirmed by the experimental results in Xe, is clearly not verified for the mixture TEA/W examined here.
