Decibel meter for personal use0.2.25 - App Store

Hello! Have you ever wondered what a noisy place this world is?
Even at night, in a quiet room, it can actually be quite noisy. By the way, regular exposure to sound above 100 decibels lead to hear damage and even permanent hearing loss.
This is not a list of facts for a horror movie, but reasons why you, like us, might once need a sound level meter.

Our application is one of the very few on the market that can not only measure the level of noise around, but also help to suppress unwanted sounds: traffic, conversations, the general environment.

We wanted to make an application that would determine the level of noise around. Minimalistic, not overloaded with extra features, but with everything you need:
- Not only measuring the noise level, but also hints when to protect yourself from it 
- Work in the background, which allows you to take measurements without even taking out your phone
- Determination of peak values ​​of the sound level and calculation of the average noise level
- Simple and clear spectral noise analysis
- Access to the history of your measurements for further analysis
- Carefully crafted UI design that will be clear to both beginners and pros

We like the result and regularly use the application for our purposes. But if you have any comments, ideas and suggestions, we will be very happy to receive your feedback.
