Auditorium Acoustic Performance Analyzer
Analyze auditorium acoustics & generate remediation strategies from measurement data
What You Can Do
You can systematically evaluate auditorium acoustic performance by inputting measured data (impulse response, RT60, speech intelligibility metrics) or simulation results, then receive detailed analysis identifying specific frequency-dependent problems, quantified deviations from ISO 3382 and AES standards, and prioritized remediation strategies. Claude cross-references your data against performance benchmarks and generates technical justifications suitable for architect presentations, client reports, and construction specifications.
Features
pinpoints specific frequency ranges causing intelligibility loss, excessive reverberation, or acoustic flutter
compares measured performance against ISO 3382, AES recommended practices, and venue-type benchmarks with deviation quantification
assesses mid-frequency reverberation across octave bands and recommends target ranges for speech vs. music venues
analyzes clarity metrics (STI, %ALcons) and identifies absorptive or diffusive treatments to improve articulation
suggests specific acoustic treatments (absorption coefficients, diffusion patterns, panel placement) with technical justification
evaluates alternative design proposals or material specifications quantitatively and ranks solutions by acoustic impact and feasibility
produces evidence-based findings with measurement data summaries, problem prioritization, and construction-ready specifications
processes EASE, ODEON, CATT-Acoustic outputs and translates complex modeling data into actionable architectural guidance
Example Output
Input: Measured RT60 data from a 2,500-seat concert hall showing 2.8 seconds at 500 Hz (target: 1.9–2.1s), 3.1s at 1kHz, and early reflection issues flagged in impulse response.
Output:
- Problem 1: Excessive Reverberation (Mid-Frequency) — RT60 is 40% above target. Root cause: hard surfaces (plaster, glass) in orchestra shell area. Impact: muddy speech intelligibility, harmonic masking during solo passages.
- Recommended Mitigation: Install 100mm rockwool absorption (NRC 0.9) on upper sidewalls (survey area: 280 m²). Expected RT60 reduction: 0.4–0.6s. Cost-feasibility: High. Timeline: 2–3 weeks.
- Problem 2: Early Flutter Echo — 125 Hz resonance between side walls (parallel 18m span). Detected via 5ms delay energy in impulse response.
- Recommended Mitigation: Deploy diffusers (QRD, 7-step design) on lower 40% of sidewalls. Expected flutter attenuation: 8–12 dB. Aesthetic integration: Acceptable as architectural feature.
Technical Justification: Changes align with ISO 3382-1:2009 recommendations for performance venues. Speech intelligibility improvement projected at +6–8% (STI metric).
