Does sound gets faster when air bubble is suspend in water?

c = sqrt(K/P)

c = speed

K = bulk module

P = density

When air bubbles is homogenized into water the density is lower, so should sound gets faster? Thank you.

• don't forget that $K=P\frac{dPr}{dP}$ where $Pr$ is pressure, so your equation becomes $c=\sqrt{\frac{dPr}{dP}}$ – Jim Apr 22 '14 at 13:46
• What do you think? Have you tried something to calculate the speed of sound through a particular concentration of bubbles in air? – user31782 Apr 22 '14 at 14:34
• Please clarify: do you want the speed of sound thru a macroscopic airbubble embedded in water, or the change of speed of sound in water full of dissolved air vs. pure water? – Carl Witthoft Apr 22 '14 at 17:02
• I am comparing between sound travelling through macroscopic air bubble in water and without air bubble. – Kevin Apr 23 '14 at 15:47
