About the sound

Headphones recommended

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

Statistical model · Not measured

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
2.0s Shared assumption without venue measurements
Room volume used
18,486m³ Assumed from the 3D shell (bounded to 8–13 m³ per seat) · 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.

A/B score comparison

Based on Estimated acoustics · Ensemble listening
A1F A Seat 197pts
Estimated acoustics · Ensemble listening
97pts
View · Balanced
85pts
Clarity–reverberation balance 40%97
Instrument delivery balance 25%94
Sound energy adequacy 35%99

Lowest component: Instrument delivery balance, 94 pts. Weaker components influence the combined score; scenarios range from 74 to 98 pts.

Scores rise when all three criteria are met together. Weights indicate importance; weaker components have more influence on the combined score.

Ensemble estimate: 74–98 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)
0.1 dB
Sound strength (G)
4.5 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 Ansan Arts Center Haedoji Theater

Compare stage views and strings, bass or full orchestra sound in A/B. Ensemble listening scores are acoustic model estimates, not on-site measurements. Tickets use block and seat number; rows are layout fields. The model retains 139 always-restricted, 12 house and 67 show-dependent OP chairs. A further 99 chairs on 2F are restricted only for shows for children under eight. This is not a verified census of all current physical chairs; 18 wheelchair spaces are separate.

What sources confirm — The official 2026 rental notice gives 1,422 operating places. Its spreadsheet and the public plan contain 1,555 chair cells and 18 wheelchair spaces, or 1,573 including 139 always-restricted chairs on 3F and 12 house seats. Restricted sales do not establish physical removal, so these remain for sightline exploration. The official stage opening is 17 × 12 m. Side and rear areas of the full 53.5 × 36.3 m stage are omitted from the scene.

What remains estimated — Audience 3D positions are estimates mapping the current plan to the official CAD section. Eight front rows, ten rear rows and one extra side row on 1F, and seven central rows on 2F, correspond to drawn treads; the model uses their midpoint distances and heights. The first central 2F tread is 20.425 m from the apron at a 9.660 m floor level; the stage is 1 m above the lower audience datum. Nine drawn 3F treads versus eight current central rows require an assumed cross-aisle correspondence. Interpolated 2F sides, 0.51 m chair spacing, fan curvature, chair-center mapping and rails remain estimates. The Chrome-viewed E6 review confirms only the side view and a show without OP seats; unknown lens/cropping prevents measured FOV claims. This is not a verified census of current physical chairs. Stage depth 18 m and musicians are illustrative; reverberation uses the common 2-second assumption.

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.
