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
23,990.4m³ 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.

A/B score comparison

Based on Estimated acoustics · Ensemble listening
A1F Front Block 3-15 Seat 599pts
Estimated acoustics · Ensemble listening
99pts
View · Balanced
79pts
Clarity–reverberation balance 45%100
Instrument delivery balance 35%96
Sound energy adequacy 20%100

Lowest component: Instrument delivery balance, 96 pts. Weaker components influence the combined score; scenarios range from 94 to 99 pts.

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

Ensemble estimate: 94–99 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)
0.5 dB
Sound strength (G)
3.7 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 Blue Square Woori Bank 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. Seat numbers follow the official seating plan. The plan does not label rows, so rows are counted from the front of each level. Pit, wheelchair and parent-and-child seats are not included.

What sources confirm — From the stage technical drawings (2025) that the operator publishes for rental clients, we read the positions of all 1,658 chairs on the 1F–3F auditorium plans, and from the same set’s longitudinal section every row’s floor height (1F, 22 rows: 0→2.69 m; 2F, 10 rows: 6.33→9.63 m; 3F, 6 rows: 12.42→15.08 m). Seats per level and per row all match the official seating plan, and seat numbers follow its labels. The 14.9 × 10 m proscenium, the stage floor at +0.93 m and the 3 m orchestra pit come from the official drawings and stage technical data.

What remains estimated — The seating plan does not label rows, so rows are counted from the front of each level, and the numbering direction reads the plan from the audience’s viewpoint. The plan has no block names either, so blocks are named by their seat-number ranges. The 76 orchestra-pit seats, 18 wheelchair spaces and 14 parent-and-child seats are not included. The section cuts only the center axis, so side blocks use the same row heights, and the balcony-front parapet applies that section’s ledge and handrail heights to the side blocks as an approximation. Walls, ceiling and acoustics are modeled.

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.
