Seongnam Arts Center Concert Hall seat view and sound experience
Sound experience
About the sound
Strings, woodwinds and brass together · Direction and distance change with your seat.
Direct sound is combined with early reflections and reverberation. Their proportions change with the seat. This is a synthesis based on assumptions, not a recording of the actual hall.
Acoustic sources and model scope
Ensemble listening estimates direct sound from five equally loud representative instruments plus early and late reflected energy. It does not trace individual wall reflections or measure sound on site. Playback uses the same energy model, but the samples' instrumentation and volume differ from the equal-strength scoring assumption. Changing a sample does not change the recommendation criteria.
- Reverberation time used
- 1.8s Operator’s stated design value · conditions not given
- Room volume used
- 19,074m³ Estimated from the 3D enclosure · Actual volume unconfirmed
We also check score variation under nine assumptions: reverberation time ±0.4 seconds and volume ±20%. Balcony obstruction, reflector placement, and instrument directivity are not included. Scores cannot rank sound quality across venues.
Acoustic method and limitationsModel calculations from the selected seat to the reference point. A larger angular size means the person appears larger.
A/B score comparison
- Estimated acoustics · Ensemble listening
- 100pts
- View · Balanced
- 69pts
Lowest component: Instrument delivery balance, 99 pts. Weaker components influence the combined score; scenarios range from 93 to 100 pts.
Scores rise when all three criteria are met together. Weights indicate importance; weaker components have more influence on the combined score.
Ensemble estimate: 93–100 pts
These are nine calculations with different assumed reverberation times and room volumes. Actual quality is not guaranteed to fall within this range, and a few points do not establish which seat is better.
- Clarity–reverberation ratio (C80)
- 0.3 dB
- Sound strength (G)
- 3.1 dB
These values come from a statistical model, not measurements. C80 is assessed against a chosen balance range rather than rewarding higher values; G is assessed for sufficient strength. View calculation criteria

Ensemble listening uses assumed direct sound, early reflections, and late reverberation. Direct-sound preference is distance-based; view scores use distance, overview, and alignment. Reflectors, balcony obstruction, and instrument directivity are not modeled, so rear-seat acoustics may also be overestimated. How to read the scores
Comparing seats at Seongnam Arts Center Concert Hall
Compare stage views and strings, bass or full orchestra sound in A/B. Ensemble listening scores are acoustic model estimates, not on-site measurements. Rows and numbers follow the operator’s seating chart. On 2F the side rows are officially L1–L3 and R1–R3 and the choir rows C1–C3; the 12 wheelchair spaces are not included. The chart marks 2F row 1 as unsold (dead) seats, so it may not be on sale.
How this experience was built
What sources confirm — Seat positions were read from the concert hall drawings (DWG) that the Seongnam Cultural Foundation publishes as rental documents. The 16 rows of 1F come from the armrest dividers in the auditorium plan bundled with the dressing-room drawing (2026), and the seven rows of the 2F rear balcony and the three side-gallery rows come directly from the lighting circuit drawing (2022). The seating-curve centres of both drawings were aligned with the stage plan (2012) so that seats and stage share one coordinate system (seat pitch 0.56 m, row pitch 0.95 m). Rows and numbers follow the operator’s seating chart (spreadsheet, 2025-03-31); the 1,090 seats plus 12 wheelchair spaces match the official 1,102. The 11.18 m stage depth, the curved stage front and the step heights of rows 1–4 (0.45 m risers; the stage is 1.35 m above the row 1 floor) are values from the stage plan and stage section.
What remains estimated — No section drawing covers 1F behind row 5, the 2F side galleries and rear balcony, or the choir seats, so their heights are estimates back-calculated from the camera height of the official seat-view photos, using where the stage front, the base of the back wall and the choir balcony front appear (about ±0.5 m on 1F, ±1.5 m on 2F). Choir rows C1–C3 have no chairs in the drawings and are an estimated layout at 0.6 m spacing inside the balcony; seats 13–21 of 1F rows 15–16 (centre) and the centre part of 2F row 1 are also missing from the drawings and continue the spacing of the neighbouring rows. The side-gallery drawing shows one more cell per row than the seating chart, so the aisle-end cell was removed. Railings, walls and ceiling are approximate, and the players are an illustrative ensemble.
Views are calculated using a 1.75 m figure, your chosen eye height and seat coordinates. Actual obstructions from people, railings or equipment and show-specific layouts may not be represented. Orchestral sound combines direction, distance and assumed early reflections and reverberation. It does not use responses measured in the actual hall. Scores indicate preference fit; actual obstructions, sound quality and price are not yet included.
Orchestral audio: original samples made from VSCO 2 CE recordings (Versilian Studios, CC0). Band and game sounds are synthesized. Crowd audio uses Sandermotions’ CC0 recordings, not recordings from this venue.
