Norsonic Nor278 Reference Sound Source

SKU: Nor278

Overview

The Nor278 Reference Sound Source is designed to produce a stable and uniform sound power output with unique long-term stability. The high sound power output makes it ideal for sound power measurements in noisy environments. The rugged, but portable and light-weight construction is perfect for field use as well a laboratory setting. Every effort has been made in the design to ensure a uniform frequency response and optimum directional characteristic well inside the requirements in ISO 6926:2016.

Applications
