SoundMeter 2D – AR Acoustic Mapping with Scientific Precision
WHY SOUNDMETER 2D?
Professional acoustic mapping used to mean expensive gear, complex workflows, and trained specialists. Not anymore. SoundMeter 2D puts advanced sound analysis in your hands, turning your iPhone into a precision acoustic instrument.
Key advantages:
- Easy-to-Use: No complicated configuration.
- Instant Visual Feedback: See sound coverage, eliminating guesswork in speaker placement and room optimization.
- Cost-Effective Analysis: Access professional-grade acoustic mapping capabilities without investing in costly measurement systems.
- Rapid Decision-Making: Generate comprehensive acoustic maps in minutes, not hours, ideal for live events, installation verification, and teaching demonstrations.
- Confidence in Your Data: Dual visualization of SPL and measurement uncertainty ensures you understand both what you're measuring and how reliable that measurement is.
- Frequency-Specific Insights: Third-octave band analysis reveals how different frequencies behave across your space, enabling targeted acoustic treatment and system tuning.
TRANSFORM YOUR SOUND MEASUREMENTS INTO INTELLIGENT, PHYSICALLY ACCURATE ACOUSTIC MAPS
SoundMeter 2D is an innovative mobile application that transforms decibel data into 2D sound maps using Gaussian Process Regression (GPR) and augmented reality (AR).
Designed for live sound engineers, acousticians, educators, and students, it allows users to measure, model, and visualize sound coverage in third-octave bands directly on an iPhone, combining scientific precision with intuitive AR interaction.
Important notes:
- SoundMeter 2D measures relative sound levels (differences between measurements), not absolute values. Calibration is not necessary.
- To achieve optimal results and maximum measurement accuracy, the use of a high-quality external microphone is strongly recommended.
KEY FEATURES
- AR-Guided Placement
Use your camera to position measurement points precisely in real space. A dynamic grid ensures accurate placement of measurement points.
- Third-Octave Band Analysis
Analyze any standard frequency band from 25 Hz to 16 kHz. The application is developed to account for pink-noise emission, take coherence into account, and interpolate data via Gaussian processes for reliable accuracy.
- Dual Scientific Mapping
Instantly visualize both Sound Pressure Level (SPL) and Uncertainty (95% CI). Understand not only the measured level, but also the confidence level behind each predicted region.
- Scientifically Rigorous GPR Engine
The algorithm integrates Class 2 uncertainty modeling, free-field, diffuse, and reverberant environment options, Tukey's IQR outlier rejection, automatic Nyquist compliance checks.
- Point-to-Point Analysis
Measure and plot SPL attenuation between any two points on the heatmaps.
- One-Tap Validation Report
Generate a concise, professional diagnostic summary and actionable optimization tips.
IDEAL FOR
- Live sound teams: Validate sound coverage and optimize mix positions
- Acoustic consultants: Document and compare room treatments with quantifiable data
- Educators and students: Visually demonstrate acoustic principles and wave behavior
- Installers and integrators: Optimize speaker layout with real data and reduce callback visits
SoundMeter 2D is a complementary acoustic measurement tool designed for practical applications. While not a certified instrument, it offers sufficient reliability for most use cases. Developed with scientific rigor using Gaussian Process Regression, standardized acoustical principles, and statistical validation, it delivers physically consistent visualizations from your measurements.
Whether you're fine-tuning a live venue or teaching wave physics, SoundMeter 2D brings high-level precision to your fingertips, with the elegance and simplicity of iOS augmented reality.
