The eastern screech owl (Megascops asio) or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. [ 1 ] [ 3 ] This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls.
When the sound source is directly in front of the owl, there is no ITD, i.e. the ITD is zero. In sound localization, ITDs are used as cues for location in the azimuth. ITD changes systematically with azimuth. Sounds to the right arrive first at the right ear; sounds to the left arrive first at the left ear.
Screech owls are typical owls belonging to the genus Megascops with 22 living species.For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.

Eastern Acoustic Works was co-founded in 1978 by partners Kenneth Berger and Kenton Forsythe, who had previously worked together at Forsythe Audio. EAW's first single enclosure system was the CS-3 designed for Carlo Sound in Nashville, Tennessee. It combined a B-215 dual 15-in low-frequency horn, a MR102 12-in mid-frequency horn and a Community ...
