Changes to notes required in reports (in response to a negative), 4. Improved direction on loudspeaker placement, 5. Potential changes in loudspeaker specification, 6. Some primarily editorial matters raised in comments on recent ballots, 7. Reorganization of the standard to move some material to annexes and incorporate practices being developed in E33.05 as they become available,86. Guidance on minimum microphone positions or measurement times for direct measurement of coupled spaces, and 9. A possible flow chart to clarify implementation of the standard.
