Optimus + Yellow sound level meter

The Optimus Yellow is the entry-level device of Cirrus’ well-renowned Optimus range. Capable of measuring the maximum noise level during a session, this device provides simple and easy-to-understand data. The Optimus Yellow is a state-of-the-art sound level meter that has been designed by the engineers at Cirrus to meet the very latest standards in noise measuring and monitoring. Most suited for applications where only simple noise level data is required, the Optimus Yellow can record the maximum sound level (LMax) in decibels, which refers to the loudest recorded noise level during a period of data capturing. This data will give you a basic understanding of the noise levels where you are measuring, and will allow you to identify any particular noise hotspots.
