PULSAR NOVA MODEL 46 – Sound Level Meter

The PULSAR NOVA MODEL 46 is a premium Class 2 octave band sound level meter, designed to deliver precise and reliable acoustic measurements across a wide range of industrial and occupational applications. Fully compliant with IEC 61672 standards, this high-performance instrument is ideal for professionals who demand accuracy, efficiency, and compliance in their noise monitoring programs.

Engineered for exceptional usability, the Model 46 combines real-time octave band analysis, comprehensive data logging, and intelligent software integration in a robust, handheld design. It simplifies complex acoustic assessments, from workplace noise monitoring to entertainment and environmental sound testing, helping you meet health and safety standards with confidence.

How It Works

The PULSAR NOVA MODEL 46 uses 1:1 real-time octave band filters that measure all frequency bands simultaneously, providing a detailed breakdown of sound energy across the spectrum. This capability enables accurate selection of hearing protection equipment (PPE) by identifying noise exposure levels at specific frequencies.

The sound meter measures A, C, and Z frequency weightings and supports Fast, Slow, and Impulse time weightings in parallel. Its integrated AnalyzerPlus software transforms raw data into actionable reports, calculating TWA/dose, Ln values, and assumed hearing protection levels. The meter’s intuitive interface and high-resolution display make setup, measurement, and reporting effortless for both novice and experienced users.
