Acoustic Simulation & Analysis
Modern audio systems require far more than simply selecting loudspeakers and amplifiers. Achieving excellent speech intelligibility, consistent coverage, musical clarity, and controlled sound distribution requires scientific acoustic analysis and precise system engineering.
At AEA, we use industry-standard acoustic simulation software and advanced engineering methods to design, optimize, and validate professional sound systems before installation begins. This approach reduces guesswork, minimizes costly revisions, and ensures predictable real-world performance.
Whether the project is a stadium, auditorium, conference center, house of worship, restaurant, ballroom, transportation terminal, or entertainment venue, our acoustic analysis process helps deliver reliable and high-performance results.
Why Acoustic Simulation Matters
A professionally engineered acoustic model allows the system performance to be evaluated before equipment is purchased or installed.
Benefits include:
- Predictable audio performance
- Improved speech intelligibility
- Consistent SPL coverage across audience areas
- Reduced acoustic problems and dead zones
- Better loudspeaker placement and aiming
- Optimization of delay systems
- Reduced feedback risks
- Improved music clarity and listener experience
- Support for consultant and tender requirements
- Reduced installation risks and commissioning time
Acoustic simulation also provides visual and measurable data that helps clients, consultants, architects, and contractors better understand the proposed system performance.
Loudspeaker Coverage Design
Proper loudspeaker positioning and aiming are critical for achieving even sound distribution throughout the audience area.
We optimize:
- Coverage angles
- Array configurations
- Vertical and horizontal aiming
- Delay loudspeaker placement
- Front fill and under-balcony coverage
- Distributed audio systems
SPL Analysis
We analyze overall sound pressure levels throughout the venue to ensure balanced and consistent audio coverage.
Analysis includes:
- Total SPL
- Direct SPL
- Broadband analysis
- 1/1 octave analysis
- 1/3 octave frequency analysis
- A-weighted calculations
This helps verify that all audience areas receive appropriate sound levels without excessive variations.
Speech Intelligibility (STI)
Speech Transmission Index (STI) analysis evaluates how clearly speech can be understood throughout the venue.
This is especially important for:
- Conference rooms
- Transportation facilities
- Houses of worship
- Stadiums
- Auditoriums
- Paging systems
- Voice evacuation systems
Our simulations help optimize intelligibility performance before installation.
Clarity Analysis
We perform detailed clarity calculations including:
- C7
- C50
- C80
- Csplit
These parameters help evaluate:
- Speech clarity
- Musical articulation
- Direct-to-reverberant balance
- Acoustic definition
This is particularly important for multipurpose venues and music-focused spaces.
Arrival Time & Delay Optimization
Arrival Time analysis allows us to evaluate sound propagation timing throughout the venue.
This helps:
- Optimize delay speaker systems
- Improve synchronization
- Reduce echo perception
- Maintain coherent sound imaging
- Improve audience listening experience
Loudspeaker Overlap Analysis
Lspk Overlap analysis identifies areas where multiple loudspeakers interact excessively.
This helps minimize:
- Comb filtering
- Phase interference
- Coverage inconsistencies
- Unwanted acoustic interactions
Direct-to-Reverberant Ratio (D/R)
D/R analysis evaluates the balance between direct sound and reflected sound energy.
This is important for:
- Speech intelligibility
- Localization accuracy
- Listener comfort
- Overall acoustic quality
3D Modeling & Visualization
AEA creates accurate 3D acoustic environments using architectural plans and venue models.
This includes:
- Audience areas
- Architectural geometry
- Loudspeaker positions
- Coverage maps
- SPL heat maps
- Acoustic prediction visuals
These visualizations help clients and project stakeholders better understand the final system design.
Acoustic Measurements
Acoustic Measurements
Accurate acoustic measurements are essential for verifying the performance of any audio system and ensuring that a space meets its intended acoustic objectives. Whether it is a conference room, auditorium, classroom, performing arts venue, house of worship, or any other critical listening environment, objective measurements provide the data needed to evaluate and improve acoustic performance.
At AEA Professional AV, we perform comprehensive acoustic assessments using professional measurement equipment and industry-leading software. Our measurements help identify acoustic issues, validate system performance, and provide recommendations for optimization before or after system commissioning.
Our acoustic measurement services include:
- Reverberation Time (RT60, EDT, T20, T30)
- Speech Intelligibility (STI / STIPA)
- Speech Clarity (C50)
- Music Clarity (C80)
- Definition (D50)
- Frequency Response Analysis
- Impulse Response Analysis
- Energy Time Curve (ETC)
- Sound Pressure Level (SPL) Measurements
- Background Noise Assessment
- System Verification and Performance Validation
Our measurement process follows internationally recognized acoustic standards whenever applicable, providing reliable and repeatable results that can be used for system commissioning, troubleshooting, optimization, or project documentation.
The collected data enables consultants, architects, contractors, and facility owners to make informed decisions regarding room acoustics, loudspeaker placement, DSP optimization, and overall system performance.
Following each measurement session, we provide a professional report that includes measured data, analysis, observations, and practical recommendations for improving acoustic performance where necessary.
Whether you are commissioning a new AV system, troubleshooting an existing installation, or evaluating the acoustic quality of a space, AEA Professional AV delivers accurate measurements and expert analysis to help you achieve the best possible listening experience.
