Recently, the LIGO observatory reported the first direct observation ofgravitational waves, with a signal consistent with a binary black hole merger.This detection triggered several follow-up searches for coincident emission inelectromagnetic waves as well as neutrinos, but no such emission was found. Inthis article, the implications of the non-detection of counterpart neutrinosare investigated using general arguments. The results are interpreted with aparameter denoting the energy emitted in neutrinos relative to the energyemitted in gravitational waves. The bound on this parameter from the diffuseastrophysical neutrino flux detected by the IceCube Neutrino Observatory isdiscussed. It is found that, currently, the non-detection of counterpartneutrinos puts a bound comparable to the one from the diffuse astrophysicalneutrino flux. This bound is then used to constrain the amount of matter in theblack hole binary environment. Finally, the sensitivity to this parameter infuture gravitational wave observation runs is investigated. It is shown how thedetection of one or more neutrinos from a single merger would stronglyconstrain the source population and evolution.
