Interior Acoustic Simulations (Geometric Method)

When conducting interior acoustic simulations (using the geometric method), we create a three-dimensional acoustic model of a room, considering all key surfaces that influence indoor acoustics. Each surface is precisely assigned its location, mounting method, and most importantly – its acoustic parameters, such as absorption and optionally, diffusion. The next step is to replicate a real measurement scenario – we define the location of sound sources and the surfaces/points where we will analyze results. This process mirrors actual acoustic measurements, only in a virtual environment. We then proceed with calculations and analysis of the obtained results.

Examples of interior acoustic simulations:

• Offices and open spaces – optimizing sound distribution and space planning to minimize noise and improve communication.
• Conference rooms – enhancing speech intelligibility for online conversations and meetings.
• Theaters, concert halls, and auditoriums – designing acoustics to improve sound clarity and music perception.

Acoustic Insulation Simulations

When performing acoustic insulation simulations, we create a three-dimensional model of a building partition, incorporating all critical physical parameters of each element. Each material is precisely defined by its unique properties – thickness, density, elasticity, damping, and response to stress. This approach allows us to obtain not only reliable numerical results (Rw/STC, C, Ctr – parameters measured in laboratory tests) but also a detailed understanding of how the partition behaves across the entire frequency spectrum. The obtained results are then analyzed further to assess the actual insulation performance of the partition after construction (in situ), considering mounting methods, adjacency to other partitions, and potential installation errors. This comprehensive approach enables a complete evaluation of insulation performance against airborne and impact noise in various construction systems.

Examples of acoustic insulation simulations:

• Partition and inter-apartment walls – determining acoustic insulation (Rw) and expected neighbor noise levels.
• Inter-floor ceilings – analyzing airborne and impact noise insulation in different finishing variants.
• Windows and facades – predicting the level of external noise entering a building based on glazing and sealing selection.
• Roofs and top-floor ceilings – assessing protection against aircraft noise and weather impact.
• Interior and exterior doors – comparing different door types in limiting sound transmission, e.g., from stairwells.
• Elevator shafts and utility risers – evaluating noise propagation from installations into residential units in multi-story buildings.
• Large-scale facilities – analyzing the impact of internally generated noise (e.g., from a server room) on adjacent rooms and common spaces.
• Commercial and retail premises – verifying the effectiveness of acoustic insulation between commercial spaces, e.g., a club or dance school in an apartment block.
• Recording studios and audiophile rooms – designing partitions with high acoustic insulation, particularly in the lowest frequency ranges.
• Sports halls and entertainment venues – limiting sound transmission (e.g., from sports events) to adjacent areas.
• Industrial facilities and production plants – analyzing the effectiveness of acoustic screens and partitions in reducing industrial noise at workstations.
• Tunnels, underground parking lots, and garages – assessing noise levels reaching adjacent residences and buildings.
• Gyms and fitness clubs – analyzing impact noise reduction for different flooring and vibration isolation layers.
• Partitions in hotels and dormitories – evaluating acoustic insulation of walls and ceilings in high-occupancy buildings to ensure acoustic comfort.
• Conference rooms and open-plan offices – modeling the effectiveness of acoustic insulation and partitions in workspaces.
• Educational facilities – analyzing insulation between classrooms and protection from hallway and common area noise.
• Hospitals and clinics – assessing the effectiveness of acoustic insulation in medical consultation rooms and patient wards for enhanced comfort.
• Subway stations and transportation hubs – simulating acoustic insulation of tunnels and soundproof barriers in transit spaces.

Listen based on simulations (Abba – Gimme! Gimme! Gimme! (A Man After Midnight), distributed by Universal Music Group) to hear the results that properly selected acoustic insulation can bring for a lightweight wall system made using drywall technology. Before listening, lower your speakers/headphones and adjust the volume. While comparing variants, try not to increase the volume – the difference and the altered sound characteristics reflect the actual performance of the wall. Thanks to insulation simulations, we can replicate similar results for any building partition based on any sound sample.

FEM Simulations and BIM Modeling

Finite Element Method (FEM) and Building Information Modeling (BIM) allow for precise replication of how structures and building systems behave before their actual construction. FEM enables us to analyze stresses, deformations, and material susceptibility to vibrations and loads, which is crucial for optimizing designs in terms of durability and acoustics. BIM allows the integration of all design aspects into one environment, facilitating cross-disciplinary collaboration and eliminating errors early in the conceptual phase. Examples of FEM and BIM simulation applications:

• Walls and ceilings – vibration analysis and the effect of various assembly techniques on sound transmission,
• Floating floor systems – optimizing vibro-isolating layers for vibration damping efficiency,
• Facade systems and glazing – modeling the impact of wind, transportation, and structural noise on buildings,
• Acoustic bridges and weak insulation points – identifying areas susceptible to sound penetration and eliminating them,
• Sports halls and large-scale facilities – structural resonance analysis and the effectiveness of acoustic screens, dynamic building analyses,
• Recording studios, rehearsal rooms, cinemas, listening rooms, and concert halls – analysis of sound pressure level distributions for the lowest resonant frequencies in spaces.

Environmental Simulations

Environmental simulations allow us to assess the impact of noise on the surrounding area and design effective solutions to reduce its environmental effects. By using numerical models, we can predict sound propagation under different terrain and weather conditions, allowing for optimization of acoustic protection already at the planning stage of a project. This allows not only precise modeling but also the creation of sound samples of simulated environments, enabling subjective experience of how specific solutions will affect the surrounding acoustics.

The environmental simulation process includes creating an acoustic model of the area, considering topography, obstacles, and sound-reflecting materials. Next, we define noise sources such as road, railway, and aircraft traffic, industrial noise, or technical installations. Sound wave propagation simulations are conducted based on changing weather conditions and times of the day. The next stage may involve analyzing the effectiveness of acoustic screens and sound-absorbing barriers and evaluating the noise levels reaching residential buildings and public spaces. Modeling also enables the assessment of the impact of urban development on increasing or reducing noise levels in a given area, with results compared to actual field measurements to fine-tune computational models.

Examples of environmental simulation applications:

• Transportation noise – predicting noise levels from roads, railways, and airports, optimizing acoustic screen layouts,
• Industrial noise – analyzing the impact of manufacturing plants and logistics centers on the surrounding area,
• New housing developments – evaluating the influence of neighboring noise sources and designing effective protective solutions,
• Recreational space noise – modeling the impact of outdoor concerts, sports areas, and amusement parks on the surrounding area,
• Quiet zones and acoustic protection areas – identifying areas requiring special noise protection,
• Effectiveness of green screens – modeling the impact of vegetation on sound damping in urban environments,
• Wind turbine noise – predicting the impact of wind farms on the environment and designing protective zones,
• Water infrastructure – modeling sound propagation around water bodies and ports,
• Construction site noise – simulating sound levels emitted by construction machinery and their impact on the surroundings,
• Interactive noise maps – creating dynamic noise level simulations for cities under different weather conditions and times of day,
• The impact of urban structures on noise propagation – analyzing sound reflection and diffraction effects from buildings, bridges, and tunnels,
• Airspace corridor noise – simulating sound propagation from aircraft along flight paths and near airports,
• Energy storage systems – simulating sound propagation in legally protected areas.

Thanks to environmental simulations, we can precisely plan urban spaces, minimize acoustic conflicts, and create more comfortable living conditions in urban environments.
