The Importance of Sightline Design and Seat Placement in Conference Halls
Introduction
One of the most ignored issues by investors in conference hall projects is line of sight. (sightline) design. However, the most critical element that determines the functionality of a hall is the angle and how clearly the audience can see the stage or curtain. The comfort of the seats, acoustic performance or lighting quality does not mean anything if the line of sight is not planned correctly. We provide.
1. What is Line of Sight?
Sight line is the unobstructed visual field required for the audience to see the stage or projection screen from their seating point. is the line.
Vertical Sightline: Vertical Sightline calculated to ensure that the head of the person sitting in front of a seat does not block the view of the person behind. angle.
Horizontal Sightline: The horizontal line determined so that the audience sitting towards the sides of the stage or screen can see the image without loss. angle.
These two parameters directly affect the seating arrangement and platform height. determines.
2. Basic Criteria in Sightline Design recommended.
Platform Height: Giving a height of at least 12–15 cm to each row to increase the visibility of the rows at the back. required.
Eye Level Calculation: The eye level of a standard audience is considered to be 115–120 cm in a sitting position. Calculations are made according to this level.
Head Obstacle Factor: In order for the head of the audience in the front row not to block the view, the eye level in the back row should be at least 12 cm above. must.
3. Importance of Seat Placement
Straight Line Placement: Requires less engineering, but does not cause visibility loss in large halls. may be.
Fan Placement: Optimizing viewing angles It is especially preferred in wide scenes.
Curved Layout: It offers optimum solutions in terms of both acoustics and sightline, but the construction cost is slightly higher. is high.
4. Nish Global's Approach
The inclination angles and platform heights of the seats are modeled in 3D environment and presented to the investor. is shown.
Points that may create visual obstructions are identified and identified before construction begins.
The 55 DNS density sponge and counterweight mechanism we use in seat ergonomics ensures long-term comfort of the audience while maintaining the correct sitting position. supports.
5. Case Example: Multi-Purpose Hall Project
In the multi-purpose hall project we completed for a municipality, a straight seating plan was initially considered. However, in sightline simulations, it was determined that stage visibility was lost by 18% in the back rows of the hall. Thereupon, elevated step platforms were applied at the rear. As a result:
Full view of the stage from all seats was achieved,
Audience satisfaction is over 95% output,
passed.
6. Sightline Checklist for the Investor should be asked:
1. Is the viewing angle of the audience in the back affected by the viewing angle of the audience in front? Can the stage be seen clearly from the seats on the side of the hall? Is the seating angle sufficient for audience comfort? Platform heights Does it comply with international standards?
5. 3D sightline simulation was made during the project phase. ?
Conclusion
Conference Sightline design in halls is one of the cornerstones of user satisfaction and success of the project. A seating arrangement that is not calculated correctly can render even the best acoustic and lighting systems dysfunctional. We offer.
