## What is NoiseScope?

NoiseScope is a precise and reliable tool for measuring and documenting sound levels in your environment. Whether you are at a concert, at work, at home, or outdoors, NoiseScope gives you an accurate understanding of the noise around you — in real time.

Measure sound levels instantly in decibels (dB) with a clear, color-coded display that helps you understand how safe or harmful the sound may be. The app also provides a rolling average to smooth out rapid fluctuations and give you a more stable picture of the overall sound environment.

Measure and store noise over time
Start a measurement period and track minimum, maximum, and average levels. With location access enabled, NoiseScope also records your position and marks it on a map, making it easy to document where a measurement took place.

Perfect for reporting noise issues
The Pro version allows you to save measurement periods and export detailed PDF reports containing all key values — time, location, and noise levels — ideal for submitting noise complaints or documenting sound conditions professionally.

The Pro Version Features
• Unlimited measurement duration
• Save measurement periods
• Export PDF reports with key data and map
• Improved documentation for noise complaints

Designed for clarity and ease of use
NoiseScope offers a clean, intuitive interface that makes noise measurement accessible to everyone. Real-time readings can be disabled at any time to reduce battery use.
Whether you need a simple sound level meter or a tool for formal documentation, NoiseScope gives you accurate, reliable, and easy-to-share results.
