| The Class 1 Sound & Vibration Analyser offers superior technical specifications, with a measuring range starting as low as 12 dBA. This device combines all essential measurement functionalities in one compact, handheld tool, designed for acoustic engineering applications such as sound insulation measurements and precise frequency or signal tonality analysis. Equipped with frequency analysis in 1/1 & 1/3 octave bands, FFT analysis, and audio recording for noise source identification, it’s the perfect instrument for professionals working with sound and vibration. The basic kit includes RT 60 measurement and signal generator functions, offering versatile solutions for various acoustic environments. Key Features: Class 1 Sound Level Meter: Meets the IEC 61672 standards for Class 1 sound level meters, with independent testing approval. Frequency Analysis: Provides 1/1 & 1/3 octave bands, FFT analysis, and real-time wave recording for comprehensive sound and vibration measurement. Real-Time Data Logging: Time-history data logging with a 2ms step for precise analysis. Tonality Analysis: Helps identify annoying tones in sound and calculates penalty values in dB as per ISO 1996-2, a standard for analyzing tonal characteristics of noise. Loudness Measurement: Calculates sound loudness in accordance with ISO 532B (Zwicker method), providing a subjective perception of sound and offering a more reliable assessment than A-weighted levels for low-level broadband sounds. G Weighting Filter: Ideal for infrasound measurements, making it suitable for use in wind farms and other specialized acoustic environments. Signal Generator: Included for conducting RT 60 measurements and further acoustic analysis. Portable Design: Compact and lightweight, offering improved compatibility with mobile apps for enhanced versatility. |
