The Norsonic range of sound meters includes:
 

• Nor117 Vehicle Noise Analyser - a sophisticated sound level meter designed with ISO 5130 vehicle noise measurements in mind. The Nor117 extracts the rpm directly from the sound level by use of advanced FFT and cepstrum technique. This means that your vehicle measurements can be made in a much faster and convenient way than before.
   
• Nor118 Sound Level Meter - a precision integrating sound level meter according to IEC 61672 class 1. This instrument is relevant to applications in (i) industrial hygiene, (ii) product development, (iii) quality control, (iv) noise mapping, (v) sound power, (vi) environmental noise, (vii) building acoustics and (viii) speech intelligibility
   
• Nor121 Real Time Analyser - specifically designed for environmental noise assessments and building acoustics, it records the sound signal itself, can be used as a stand-alone building acoustics mode - no PC needed, includes pure tone detection mode and with parallel measurement reports with six levels of nesting each having individual time settings plus profile and event based data, plus many more capabilities.
   
• Nor131/132 Sound Level Meter - The Nor130 Series of Sound Level Meters are designed and manufactured to the latest sound level meter standards and comprises two products. The Nor131 is a Class 1 (precision) instrument whilst the Nor132 is designed in accordance with the less accurate Class 2 requirements. Both meters offer the same features with exception of the detachable preamplifier which is only available on the Nor131 version.
   
• Nor137 Vehicle Noise Meter - The Nor137 Vehicle Noise Meter is specially designed for in-the-field stationary vehicle noise test measurements in accordance with ISO 5130 or similar national standards. For use in connection with an external rpm detector unit.
