What is Acoustic Simulation? Where and Why Is It Used?

When designing a conference hall, it’s not just about the seating arrangement or stage setup. One of the most critical factors that directly determines the success of any event is the acoustic quality of the space. This is where acoustic simulation steps in—not just as a technical process, but as a sophisticated blend of science, software, and spatial intelligence.

🧠 What is Acoustic Simulation?

Acoustic simulation is a scientific method of digitally modeling how sound behaves in an enclosed space—how it travels, reflects, disperses, and fades out.

Even before construction begins, we can calculate:

🔊 Where echoes are likely to occur

🎯 Which seating zones may have reduced speech clarity

🧱 Which surfaces should absorb or reflect sound

In short, it allows us to optimize the space not only for aesthetics and function, but for auditory excellence.

🌍 Global Acoustic Performance Standards

Acoustic simulations are performed according to internationally recognized criteria, especially in large public venues. The most common metrics include:

RT60 (Reverberation Time): How long a sound lingers in a room before fading—critical for speech clarity

STI (Speech Transmission Index): Measures how intelligible speech is to the audience

SPL (Sound Pressure Level): How loud the sound is at different points in the space

C50 / C80: Determine early and late reflection balance, essential for both speech and music environments

European projects typically follow DIN 18041, ISO 3382, and EN 60268, while U.S.-based projects rely on ANSI S12.60—especially in educational facilities.

🧪 Nish Global: Acoustic Simulation Test Center

At Nish Global, we don’t just build halls or install seats—we also operate as a fully equipped Acoustic Simulation Test Center. This means we support both public and private sector projects with certified, data-driven acoustic services.

Here’s what we provide:

📊 3D acoustic modeling of architectural plans before construction

📉 RT60, STI, and SPL analysis in compliance with international standards

🧮 Real-time simulations using advanced tools like ODEON, EASE, and CATT-Acoustic

📄 Official acoustic reports for design approvals and public tenders

🛠 Optimization of materials and layout based on simulation results

Nish Global is one of the few firms in Turkey to offer this level of acoustic expertise as part of its integrated turnkey solutions.

🏛 Where Is Acoustic Simulation Required?

University auditoriums

Cultural and congress centers

Municipal multi-purpose halls

Libraries and museums

Houses of worship

Cinemas and theaters

In many international tenders and public construction projects, acoustic simulation is not optional—it’s mandatory. Lack of proper simulation often leads to post-construction complaints and costly renovations.

🧱 Acoustic Design is Not Just About Panels

Many people think “acoustics” simply means sticking some foam on the wall. In reality, acoustic design requires a deeper understanding of:

The geometry of the space

Seat back height and placement

Ceiling angles and slopes

Stage-to-audience orientation

Material reflection and absorption values

It’s a discipline that combines physics, architecture, and experience.

🚀 What Does Nish Global Do?

We don’t just place seats—we shape the sound experience of your entire space.

Identify and eliminate potential acoustic problems early

Choose the right materials, layouts, and geometries

Deliver solutions aligned with international building codes

Accelerate approval and inspection processes

Turn your hall into a place of both visual and acoustic excellence
