Environmental Noise Monitoring | Instrument Selection and Standards

Environmental noise monitoring requires instruments that perform reliably over extended deployment periods in harsh outdoor conditions. Temperature extremes, humidity, wind, and precipitation all challenge measurement accuracy. The defensibility of your data depends on demonstrated calibration stability throughout the monitoring period.

• ISO 1996-1 and ISO 1996-2: Environmental noise description and assessment
• IEC 61672-1: Class 1 sound level meter specifications
• IP55 or IP67 rated weatherproof housings for outdoor deployment
• Wind noise rejection with foam windscreen and nose cone
• Long-term calibration stability for defensible monitoring records
