AWA5662 Class 1 Multifunction Sound Level Meter
The AWA5662 is a professional Class 1 sound level meter designed for environmental, workplace, industrial and machinery noise measurement.
It provides a cost-effective step up from Class 2 instruments for users who require Class 1 accuracy, without necessarily needing the broader modular capabilities of a higher-end acoustic analyser.
Choose from integrating, statistical or octave-analysis configurations, with additional specialist options available for occupational noise exposure and unusually low or high sound pressure levels.

Choose Your AWA5662 Configuration
| Configuration | Best For | Main Capability |
|---|---|---|
| Option 1 – Integrating | General professional Class 1 noise measurement | Leq / integrating measurement, logging, recording and measurement storage |
| Option 3 – Statistical | Environmental, community and industrial noise surveys | Integrating measurement + statistical Ln analysis |
| Option 7 – RTA + Statistical | Advanced noise investigation and frequency analysis | Statistical analysis + real-time 1/1 & 1/3 octave analysis |
Integrating
The best starting point for users who require Class 1 accuracy for general professional noise measurement.
Suitable for:
- Machinery and equipment noise
- Workplace measurements
- Factory and industrial noise
- Environmental surveys
- Boundary noise measurement
Integrating measurement allows average sound levels such as Leq to be assessed over a measurement period rather than relying only on instantaneous readings.
Statistical
Designed for environmental and community noise applications where the distribution of sound levels over time is important.
In addition to integrating measurement, this configuration provides statistical Ln analysis, making it particularly suitable for:
- Environmental noise surveys
- Community noise
- Traffic noise
- Industrial boundary measurements
- Long-duration noise assessment
RTA + Statistical
The most capable of our recommended AWA5662 configurations.
It combines statistical measurement with real-time 1/1 octave and 1/3 octave frequency analysis, allowing the user to identify which frequency bands are contributing to the measured noise.
Ideal for:
- Noise-source identification
- Machinery noise investigation
- Engineering noise control
- Environmental acoustic investigations
- Frequency analysis and troubleshooting
Other Configurations Available
The AWA5662 platform can also be supplied for more specialised applications.
