Transform your iPhone into a powerful sound level meter with dBMeter Pro. Whether you are analyzing ambient noise, testing audio equipment, or simply curious about your environment, dBMeter Pro delivers accurate decibel readings with an intuitive interface. Key Capabilities: - Dual-Input Measurement: Seamlessly switch between the iPhone’s built-in microphone for quick checks or connect external measuring microphones for enhanced precision. - Contextual Reference Guide: Don’t just read numbers-understand them. Our visual reference view compares current noise levels to real-world examples (like a library, traffic, or a rock concert) for instant context. - Long-Term Data Logging: Need to monitor noise over time? Record up to 12 hours of continuous samples. - Data Export: Easily export your sessions as CSV files for deep-dive analytics and archiving.
