Sonofusion eller boblefusion er en proces, hvor deuteriums atomkerner (tung brint) formodes at smelte sammen (fusionere) ved høje temperaturer under sonoluminiscente implosioner og danne nyt stof (helium eller tritium).
De seneste analyser af Taleyarkhans gruppes eksperimenter og replikering af gruppens eksperimenter har ikke kunnet påvise sonofusion.   Man har ikke kunnet kæde de målte neutroner sammen med forekomsten af sonoluminescens.
Det betyder dog ikke nødvendigvis, at det er umuligt at lave sonofusion, men det er ikke endnu lavet overbevisende i praksis.

All four detectors produced the same results: a statistically significant increase in the amount of nuclear emissions due to sonofusion when compared to background levels..."

The measured neutron energy was ⇐ 2.45 MeV, which is indicative of deuterium-deuterium (D-D) fusion. Neutron emission rates were in the range ~5×103 n/s to ~104 n/s and followed the inverse law dependence with distance..."

Now it remains to be seen how the physics community will respond to these results..."

To their surprise, they found temperatures could reach as high as 20,000 K..."Our results are in such a different set of experimental parameters that they can neither confirm or deny Taleyarkhan’s claims to fusion," Suslick told PhysicsWeb. "A plasma is a prerequisite but certainly not a sufficient condition for fusion."..."
