**Professional Decibel Measurement with Three Flexible Modes**

Wonder Decibel offers three data collection methods: real-time monitoring, photo-based measurement, and video-based measurement, covering a wide range of use cases. The real-time mode is ideal for instant noise assessment, the photo mode freezes measurement results within captured images, and the video mode supports extended continuous recording for later review and verification. Whether dealing with sudden high-frequency spikes or persistent ambient background noise, you can quickly obtain accurate and dependable decibel readings.

**Multi-Result Correlation Analysis to Uncover Sound Variation Patterns**

By correlating and comparing measurement data from multiple sessions or different time points, the system automatically generates trend curves and fluctuation charts that clearly illustrate how sound intensity evolves over time. With multi-dimensional analytical tools including peak markings, average references, and time-segmented comparisons, you can extract critical insights from complex datasets and gain a deeper understanding of the underlying logic and patterns governing acoustic environments.

**Automated Inspection Reports with One-Tap Document Generation**

Based on collected measurement data, the system automatically produces professionally structured and visually clear inspection reports, covering measurement overviews, data charts, peak statistics, and trend analyses. Reports can be exported in standard formats for local archiving, email distribution, or print output, meeting the documentation requirements of formal scenarios such as project acceptance, environmental assessments, and academic record-keeping.

**AR-Enhanced Sound Hotspot Recognition**

Leveraging the augmented reality capabilities of iOS devices, Wonder Decibel visualizes sound decibel hotspots by overlaying them onto the real-world environment through the device screen. With a simple movement of your device, you can intuitively observe the spatial distribution of sound energy and quickly pinpoint noise-concentrated areas or anomalous sound sources. This feature proves especially valuable in scenarios such as conference room acoustic inspections, equipment noise diagnostics, and indoor acoustic layout optimization where spatial positioning is essential.

**Quiet Map – Location-Based Sound Detection**

Powered by GPS positioning, Wonder Decibel allows you to mark and record sound decibel values at different locations directly on a real map, building your personal sound map. Whether you are documenting noise distribution across urban neighborhoods, seeking out qui
