Scattering events around a supermassive black hole will occasionally toss astellar-mass compact object into an orbit around the supermassive black hole,beginning an extreme mass ratio inspiral. The early stages of such a highlyeccentric orbit will not produce detectable gravitational waves as the sourcewill only be in a suitable frequency band briefly when it is close to periapsisduring each long-period orbit. This burst of emission, firmly in the millihertzband is the gravitational wave peep. While a single peep is not likely to bedetectable, if we consider an ensemble of such subthreshold sources, spreadacross the universe, together they produce an unresolvable background noisethat may obscure sources otherwise detectable by the Laser Interferometer SpaceAntenna, the proposed space-based gravitational wave detector. Previous studiesof the extreme mass ratio burst signal confusion background focused more onparabolic orbits going very near the supermassive black hole and on events nearthe galactic center. We seek to improve this characterization by implementingnumerical kludge waveforms that can calculate highly eccentric orbits withrelativistic effects focusing on orbits which are farther away from thesupermassive black hole and thus less likely to be detectable on their own, butwill otherwise contribute to the background signal confusion noise. Here wepresent the waveforms and spectra of the gravitational wave peeps generatedfrom recent calculations of extreme mass ratio inspirals/bursts captureparameters and discuss how these can be used to estimate the signal confusionnoise generated by such events.
