Cirrus Research

In-Depth Analysis

Cirrus Research is a UK-based manufacturer of noise measurement instruments with a focus on making professional acoustical measurement accessible to safety professionals who may not be specialist acousticians. Their Optimus sound level meters provide Class 1 and Class 2 measurements with an intuitive interface that guides users through noise assessments with on-screen help and automated measurement protocols. The doseBadge personal noise dosimeter is a cable-free, shoulder-mounted device that provides full-shift noise exposure measurements without the compliance issues associated with traditional cable-connected dosimeters (workers removing microphones or placing them under clothing). Cirrus's Invictus environmental noise monitoring system provides outdoor monitoring with real-time data access, automated alerting, and audio recording for source identification. The NoiseTools software provides analysis, reporting, and compliance assessment tools that generate reports formatted for specific regulatory frameworks (UK CNOSSOS, EU END, OSHA, EPA). Cirrus Research has built a reputation for exceptional customer support and training, offering noise measurement training courses alongside their instruments to ensure customers can conduct valid assessments independently.
