TL;DR
VRASQA and AcousPlan both promise automated acoustic planning — enter room dimensions, get material recommendations, check compliance. The automation philosophies differ. VRASQA focuses on optimized material placement through algorithmic surface assignment, primarily for European markets. AcousPlan combines AI-driven material prescription with a 5,600-material database spanning 27 countries, 13 building code standards, and automated compliance reporting. Both tools save time compared to manual calculation. The right choice depends on your geographic market, the standards you work with, and whether you need compliance documentation beyond RT60.
The Automation Promise
Automated acoustic planning tools exist because the manual workflow is tedious and error-prone. A typical compliance calculation for a single room involves: measuring or estimating 6 surface areas, finding absorption coefficients for 4–6 materials across 6 octave bands, running Sabine or Eyring equations at each frequency, comparing results against 1–3 applicable standards, and formatting the output into a client deliverable. For a 20-room school project, multiply by 20.
Both VRASQA and AcousPlan automate portions of this workflow. The question is which portions, how deeply, and for which geographic markets.
What VRASQA Brings to the Table
VRASQA (Virtual Room Acoustic System for Quality Assessment) entered the European acoustic software market around 2022, targeting consultancies that need faster RT60 compliance workflows. The platform has built a following among Scandinavian and Central European practices.
Core Strengths
Algorithmic optimization. VRASQA's primary differentiator is its optimization engine. Given a room geometry and a target RT60, the platform algorithmically assigns materials to surfaces to meet the target while minimizing treatment area or cost. This is a constrained optimization problem — similar in principle to AcousPlan's auto-solve feature, but with a different algorithmic approach.
European standard focus. VRASQA was built for the European regulatory landscape. It handles ISO 3382 variants, Scandinavian standards (SS 25268, NS 8175), and Central European codes fluently. For a consultant in Stockholm working exclusively with Swedish building regulations, VRASQA's standard coverage is well-aligned.
Clean interface. VRASQA's user interface is minimal and focused. Room entry is fast, results are clearly presented, and the workflow from geometry to compliance check involves fewer clicks than many competing tools.
Limitations
Material database size. VRASQA's material library is significantly smaller than AcousPlan's 5,600-product database. The available materials are weighted toward European manufacturers, which limits utility for projects in Australia, Asia, the Middle East, and the Americas.
Building code coverage. VRASQA's compliance checking is focused on European and Scandinavian standards. Global certifications — WELL v2, LEED, ASHRAE — and non-European national codes — NCC 2022, IBC 2021, NBR 15575 — are not fully supported.
Reporting. VRASQA generates calculation summaries but does not produce the formatted, standard-specific compliance reports that many certification workflows require. Report formatting remains a manual step.
What AcousPlan Brings to the Table
Core Strengths
Material database depth. 5,600+ products from 115 manufacturers across 27 countries. Each entry includes octave-band absorption coefficients (125–4000 Hz), NRC rating, indicative cost per m², embodied carbon (kg CO₂e/m²), fire rating, and surface type classification. The database covers manufacturers from Rockfon and Ecophon in Europe to CSR Bradford in Australia and CertainTeed in North America.
AI material prescription. AcousPlan's prescription engine does not simply search for materials that meet a target absorption coefficient. It considers room function, budget constraints, aesthetic preferences (exposed vs. concealed, color range), fire rating requirements, and sustainability targets. The AI recommends a 3-tier treatment plan: minimum compliance, recommended, and premium.
13-standard compliance checking. A single simulation checks against ISO 3382-1/2/3, WELL v2 Feature 74, LEED EQ Credit, ANSI S12.60, BB93, DIN 18041, NCC 2022, NRA 2000, IBC 2021, SS 25268, ASHRAE 189.1, WHO Noise Guidelines, and NBR 15575. Compliance status is colour-coded per standard, and failing parameters are highlighted with specific remediation guidance.

Automated report generation. PDF and DOCX reports formatted per standard requirements, including calculation methodology citations, material schedules with manufacturer references, and compliance summary tables. Report generation takes under 10 seconds.
Global coverage. Projects in Singapore, Dubai, Sydney, Sao Paulo, and London all find relevant materials and applicable building codes in the same platform.
Limitations
No ray tracing. AcousPlan uses Sabine and Eyring equations, not geometric ray tracing. For acoustically complex spaces with coupled volumes, focused reflections, or highly non-uniform geometries, statistical methods have known accuracy limitations.
Rectangular bias. While AcousPlan supports L-shaped, T-shaped, U-shaped, and trapezoidal rooms, it does not handle arbitrary curved geometries or rooms with significant height variation.

Choosing Between Them: Three Scenarios
Scenario 1: Stockholm Office Fit-Out
A Swedish architect designing a 400 m² open-plan office that must comply with SS 25268 and AFS 2020:1 (Swedish workplace noise regulation). The material specification will use Ecophon, Rockfon, and Troldtekt products available from Swedish distributors.
Better fit: Either tool. Both VRASQA and AcousPlan cover SS 25268 and carry Scandinavian manufacturers in their databases. VRASQA's tighter integration with Nordic standards may offer a marginally smoother workflow. AcousPlan's broader standard coverage (WELL v2, if the project pursues certification) and larger material database provide options that VRASQA does not.
Scenario 2: Sydney School Campus
An Australian architect designing 30 classrooms for a new primary school that must comply with NCC 2022 Volume 1 Section F5 and AS/NZS 2107:2016. Material specification must use products available from Australian distributors with NCC-compliant fire ratings.
Better fit: AcousPlan. VRASQA's European focus means limited Australian manufacturer coverage and no automated NCC 2022 compliance checking. AcousPlan's database includes CSR Bradford, Autex, and other Australian manufacturers, and NCC 2022 is one of the 13 supported compliance standards.
Scenario 3: Dubai Mixed-Use Tower
An acoustic consultant assessing 50 rooms across a mixed-use development — hotel rooms, restaurants, conference facilities, retail — requiring compliance with Dubai Municipality building regulations, WELL v2 (for the office floors), and LEED (for the overall development).
Better fit: AcousPlan. The combination of WELL v2, LEED, and regional building code requirements across multiple room types is AcousPlan's core use case. Multi-standard compliance checking, automated reporting, and a material database with Middle Eastern manufacturer coverage provide a complete workflow. VRASQA's European standard focus does not extend to Gulf region requirements.
The Automation Gap Neither Tool Fills
Both VRASQA and AcousPlan automate the "what material, where" question using statistical acoustic methods. Neither tool handles the cases where statistical methods are insufficient:
- Rooms with strong flutter echo paths between parallel reflective surfaces
- Coupled volumes where energy exchange between spaces affects decay curves
- Rooms where geometric focusing (concave surfaces) creates hot spots
- Spaces where low-frequency modal behavior dominates the acoustic character
Summary
VRASQA is a well-built automation tool for European acoustic compliance. AcousPlan is a broader platform with global coverage, a larger material database, more building codes, and AI-driven material prescription. For consultancies working exclusively in Scandinavia and Central Europe, VRASQA is a credible option. For firms with international project portfolios, or projects requiring WELL/LEED certification, AcousPlan's wider scope makes it the more versatile choice.
The automation landscape in acoustic design is still young. Both tools represent a meaningful improvement over the Excel-and-PDF-datasheet workflow that most of the industry still uses. The better question may not be "which automation tool?" but "why are you still doing this manually?"
