Why you need this product Provides reliable sound pressure measurements for testing, monitoring, and troubleshooting acoustic environments. Helps you identify noise issues, verify acoustic performance, and document compliance or improvement needs with clear, quantifiable data. Accurate and repeatable readings reduce uncertainty in decisions about mitigation, equipment tuning, or safety measures. What it does and how it solves problems Measures sound pressure levels across a useful audible range, capturing both lowfrequency and mid/frequency content relevant to most acoustic assessments. Wide measurement range (30–130 dBA) covers quiet background noise up to level environments so you can use it in offices, industrial sites, or performance spaces without changing equipment. A 50 dB dynamic range preserves detail between soft and loud events, improving detection of transient or mixedlevel sound sources. Standout performance accuracy at reference frequency: ±1.5 dB at 94 dB @ 1 kHz — delivers precise, trusted readings where calibration and repeatability matter most. Extendedfrequency tolerance: ±5 dB at 94 dB @ 8 kHz — maintains usable accuracy at higher frequencies often present in equipment noise or speech intelligibility checks. Frequency response of 30 Hz–8 kHz captures the key audible band for most practical measurements while minimizing irrelevant extremes. Key specifications Sound pressure accuracy: ±1.5 dB (94 dB @ 1 kHz), ±5 dB (94 dB @ 8 kHz) Frequency response: 30 Hz–8 kHz Dynamic range: 50 dB Measurement range: 30–130 dBA Practical applications Workplace noise assessment: Evaluate machinery and productionfloor noise to inform hearing protection policies and noisecontrol measures. Audio system setup and calibration: Tune speakers and livesound systems by measuring levels and frequency content to achieve balanced coverage. Environmental and facility monitoring: Track background and event noise in residential areas, construction sites, or campus settings to document conditions and guide mitigation. What to expect in use Consistent, repeatable level readings suitable for comparison over time or between locations. Clear measurement coverage for most commercial, industrial, and consumer audio tasks thanks to its 30 Hz–8 kHz frequency response and 30–130 dBA range. Reliable performance where accuracy at the 1 kHz reference is critical, with acceptable frequency tolerance for broader acoustic assessments. If you need precise sound pressure measurements across typical audible frequencies and a broad dBA range for monitoring, calibration, or assessment tasks, this product delivers the essential performance metrics required for practical, trustworthy results.
