  Merging binary systems consisting of two collapsed objects are among the most
promising sources of high frequency gravitational wave, GW, signals for ground
based interferometers. Double neutron star or black hole/neutron star mergers
are also believed to give rise to short hard bursts, SHBs, a subclass of gamma
ray bursts. SHBs might thus provide a powerful way to infer the merger rate of
two-collapsed object binaries. Under the hypothesis that most SHBs originate
from double neutron star or black hole/neutron star mergers, we outline here a
method to estimate the incidence of merging events from dynamically formed
binaries in globular clusters and infer the corresponding GW event rate that
can be detected with Advanced LIGO/Virgo. In particular a sizeable fraction of
detectable GW events is expected to be coincident with SHBs. The beaming and
redshift distribution of SHBs are reassessed and their luminosity function
constrained by using the results from recent SHBs observations. We confirm that
a substantial fraction of SHBs goes off at low redshifts, where the merging of
systems formed in globular clusters through dynamical interactions is expected.
