"Decibel Pro" turns your IOS device to professional and pre-calibrated sound level meter with optimal precision and accuracy.

Are you concerning about workplace safety, monitoring noise pollution, or just curious about the sound levels in your surroundings? "Decibel Pro" helps protect your hearing and health.

#Key Features and Functionality

1. Sound Level Meter:
- Instant Sound Level (dB): "Decibel Pro" offers real-time measurement of sound levels, giving you an instant reading of the decibel (dB) level in your surroundings.
- Mix and Max dB: "Decibel Pro" allows you to track the minimum and maximum sound levels over a set period, enabling you to monitor fluctuations in noise.

2. Chart Display:
- Visualize your sound level data with intuitive charts, making it easy to analyze trends and patterns in the noise around you.

3. Dosimeter:
- Time-Weighted Average (TWA): Decibel Pro calculates the TWA, which is a critical metric for assessing long-term exposure to noise, helping you stay within safe limits.
- Dose and Projected Dose: Keep track of your accumulated noise exposure (dose) and projected dose for a given period, ensuring you remain within recommended safety thresholds.

4. OSHA and NIOSH Standards:
- "Decibel Pro" is designed in accordance with OSHA (Occupational Safety and Health Administration) and NIOSH (National Institute for Occupational Safety and Health) standards, ensuring you have access to the most reliable and up-to-date guidelines for safe noise levels.

5. Calibration:
- The app provides calibration options, allowing you to fine-tune the accuracy of your measurements for optimal results.
- Custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.
