Narrative:

Our clearance stated to fly the 'noise abatement procedure northeast.' after departure, we followed the northeast 'noise abatement IFR procedure' and turned 'right (nebound) as soon as practicable.' the northeast departure states to intercept the assigned ATC heading or radial, however none was assigned. On switching radios to departure, we queried as to which heading nebound to fly. In response, the controller queried our heading and proceeded by assigning us immediate headings to which we complied. It was apparent that there was confusion on the controller's behalf as to why we were nebound. The rest of the flight was normal.
