The Pulsar Environmental Noise Meter–Model 45 (Class 1) is a premium, high-accuracy sound level meter engineered for precise environmental and occupational noise assessment. Designed to deliver reliable, regulation-compliant noise measurement data, this instrument is ideal for professionals conducting environmental impact studies, construction noise compliance, workplace noise surveys, and industrial noise monitoring.
As a Class 1 sound level meter, the Model 45 meets the highest international standards for acoustic measurement accuracy-providing tighter tolerances and broader frequency response compared to general-purpose models. This makes it especially suited for regulatory studies and environmental noise surveys where high-precision, defensible data is critical.
Captures sound levels from 20 dB(A) to 140 dB(A) and 143 dB(C), enabling both quiet ambient noise study and high-level noise capture.
Ensures industry-leading accuracy with minimal measurement tolerance- ideal for environmental regulatory compliance and scientific analysis
Provides detailed frequency analysis for deeper insight into noise characteristics
Measures standard noise parameters including Leq, peak levels, statistical Ln values, and TWA/dose metrics to support detailed noise reporting
Equipped with AnalyzerPlus software for intuitive data download, analysis, and professional report generation
Allows for audio tagging and notes during measurement, adding context to recorded data. .
Engineered for use across environmental surveying, construction sites, industrial facilities, and urban noise assessments
Ideal for community noise, traffic noise studies, and regulatory environmental assessments
Supports compliance with local and international noise standards during building and infrastructure projects.
Used in workplace noise risk assessments to protect worker hearing and meet occupational safety requirements
Suita ble for detailed evaluation of machinery noise emissions.
Built to meet global acoustic standards and certified for precision performance, the Model 45 adheres to international measurement requirements-enabling noise professionals to confidently deliver accurate, traceable results for both environmental and safety compliance projects.
