## What is Sound Decibel Meter?

Our app is developed to measure the level of ambient noises. We have tried to make it as clear, simple and accurate as possible so that each person has the opportunity to quickly measure and monitor hearing health.

To ensure precision, we calibrated our app using a real professional-grade sound meter.

Key Features:

- Smart AI noise meter to detect noise type
- Accurate sound pressure measurements
- Various types of audio waves
- Sync with the Health app - track noise levels and monitor your hearing health
- Reference table to compare noise levels
- Various types of measurements: dBa, dBc, dBz
- Sound recording and noise data saving
- Possibility to share records
- Convenient dosimeter
- Selection of standards for allowable hearing loads: OSHA and NIOSH
- Measurement range from 20db to 160db
- Microphone calibration for more accurate measurements
- Response speed settings
- User-friendly and intuitive interface
- Display of current, average and maximum values

Our app has the possibility to synchronize with the Health app. To do this, you need to go to the app settings and turn on the health tab there. After that, information about the volume of the ambient noise will be transmitted to the Health app, so you can track the amount of consumed noise. You can also set the interval of data on the incoming noise.

The app uses a microphone to track the sound pressure level. You can record information about the ambient noise in real time, as well as save all data in a playlist so that you can return to this data at any time.

Do you work in high noise environments? Do you want to find out if the neighbors are not exceeding the permissible volume values? Or maybe you want to monitor the health of your ears? If yes, our app can serve you as a faithful assistant.

Important! The application does not guarantee a 100% result, since the measurements you obtain depend on your device and may contain inaccuracies. For a more accurate result, it is better to calibrate the app or compare the obtained data with a professional sound level meter.

*2025-01-06*

In a silent room the app says it is 50 - 75 decibels. With tv turned up to top volume it said 80. I am guessing the 5 star reviews were Bought. Do not waste your money. Buyer Beware!
