Before it’s built, listen first.
We predict absorption, blocking, and masking outcomes straight from drawings. With a licensed Treble wave-based simulator, we run accurate low-frequency (≤ 250 Hz) simulations and compare RT60, C50, STI, and SPL distributions across material combinations—avoiding over-construction and trimming budgets. All we need are the drawings.

Process
Process flow.
Five steps from drawing intake to report delivery. Iteration headroom is built in so material combinations can be tuned two or three times.
Step · 01
Brief intake
2D plans and sections, occupancy, intended use, and target RT60—that's all we need to start.
Step · 02
Engine matching · modeling
We select an engine—Treble (wave-based), Odeon (ray-tracing), or CATT (hybrid)—based on volume, low-frequency dependence, and geometric complexity, then build the 3D mesh.
Step · 03
Per-track simulation
We simulate all three tracks—absorption (RT60 · C50 · STI), blocking (SPL ingress · partitions), masking (SPL uniformity)—across two or three material combinations.
Step · 04
Auralization
We render listening samples (WAV) from 3–5 seat positions so the owner can decide on what they will actually hear.
Step · 05
Report delivery
A 1-page summary, heatmaps, BOM, and tuning notes—delivered as PDF and XLSX.
Solutions
Predict: Absorb · Block · Mask.
All three tracks are predicted quantitatively from drawings. We select the engine based on space type.
Track 01 · Absorb
흡음 예측
Across material combinations, we predict RT60 (reverberation), C50 (clarity), STI (speech intelligibility), and D50 in octave bands—locking in the combination that meets targets before construction. We also render listening samples (WAV) from 3–5 seat positions so the owner can decide on what they will actually hear. *We select Treble (wave-based) for typical rooms and recording studios where low-frequency accuracy matters, Odeon (ray-tracing) for large halls and auditoria, and CATT (hybrid) for complex geometries.*

차음 예측
We model traffic and mechanical noise ingress, partition isolation, and floor-to-floor impact transmission before construction begins. By comparing the impact of facade specs, window STC ratings, and floor assembly changes, we return the lowest-cost combination that hits the NC and STC targets. *We select Treble (wave-based) or Odeon (ray-tracing) based on space size.*

마스킹 예측
We predict SPL distribution uniformity (within ±2 dB) for the masking system, locking in speaker layout, spacing, and zone output ahead of time. Paired with speech privacy metrics (DA · rD), we estimate the final commissioning targets during design. *We combine Treble's sound-field simulation with ASTM E1573 and ISO 3382-3 evaluation models in the deliverable.*

When
When to engage.
Prediction works best between schematic design and construction documents. After that, the cost of changes rises sharply.
✓ 적합한 시점
- Schematic design complete, about to enter construction documents
- When you need to compare material combinations for selection
- New cultural facilities, performance venues, and large offices
- Projects with acoustic criteria (RT60 · STI) specified in the RFP
- When you want to give the owner a listening sample
⚠ 효과가 제한되는 경우
- Once construction has started — material changes are constrained
- Without drawings, with only a site visit
- Undecided use or movable partitions — measure alone is recommended
- Small meeting rooms ≤ 30 m² — a simple calculation suffices
