AWA5662 Class 1 Multifunction Sound Level Meter
The AWA5662 is a professional Class 1 multifunction 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 higher-end acoustic analysers.
Choose from integrating, statistical and real-time octave-analysis configurations, with specialist versions also available for occupational noise exposure and unusually low or high sound pressure levels.

- Workplace noise investigations
Statistical Ln measurements are particularly useful where percentile noise levels are required in addition to Leq.
Option 7 – RTA + Statistical
The most capable of our standard AWA5662 configurations.
This version combines:
- Integrating measurement
- Statistical Ln analysis
- Real-time 1/1 octave analysis
- Real-time 1/3 octave analysis
- Time-history data logging
- Audio recording
- 4 GB internal memory

The octave analyzers allow the user to identify which frequency bands are contributing to the measured noise.
Suitable for:
- Noise-source identification
- Machinery noise investigation
- Engineering noise control
- Environmental acoustic investigations
- Industrial noise troubleshooting
- Frequency spectrum analysis
- Advanced environmental surveys
Other AWA5662 Configurations Available
The AWA5662 can also be supplied in other factory configurations for more specialised applications.
| Configuration | Main Functions | Best For |
|---|---|---|
| Option 1 – Integrating | Integrating + Logging / Recording + Bluetooth | General Class 1 measurements |
| Option 2 – Integrating + Printer | Integrating + Logging / Recording + Bluetooth + Mini Printer | Field measurements requiring printed results |
| Option 3 – Statistical | Integrating + Statistical + Logging / Recording + Bluetooth | Environmental and community noise |
| Option 4 – TWA / Dose | TWA / Dose + Logging / Recording | Occupational noise exposure |
| Option 5 – Statistical + Printer | Integrating + Statistical + Logging / Recording + Bluetooth + Mini Printer | Environmental surveys requiring printed results |
| Option 6 – RTA | Integrating + 1/1 & 1/3 Octave + Logging / Recording | Frequency and noise-source analysis |
| Option 7 – RTA + Statistical | Integrating + Statistical + 1/1 & 1/3 Octave + Logging / Recording | Advanced environmental and frequency analysis |
| Option 8 – High SPL | Integrating + Logging / Recording with specialist high-level microphone | High and ultra-high sound pressure measurement |
| Option 9 – Low SPL | Integrating + Logging / Recording with low-noise microphone | Quiet environments and low-level acoustics |
Occupational Noise / TWA & Dose
Option 4 is designed specifically for occupational and workplace noise exposure measurement.
This configuration provides TWA / Dose measurement together with time-history logging and recording.
Suitable for:
- Occupational hygiene
- Workplace noise exposure assessment
- Industrial health and safety
- Shift-based exposure measurements
- Professional occupational noise surveys
1/1 & 1/3 Octave Analysis
Options 6 and 7 provide real-time spectrum analysis using both:
- 1/1 octave bands
- 1/3 octave bands
These functions allow the frequency content of a noise source to be investigated rather than measuring only its overall sound level.
Typical applications include:
- Machinery noise
- Industrial acoustics
- Noise-source identification
- Engineering noise control
- Environmental investigations
- Acoustic troubleshooting
Option 6 provides octave analysis without statistical analysis.
Option 7 combines octave analysis with statistical Ln measurements and is therefore the better choice for advanced environmental noise work.
High Sound Pressure Measurement
The AWA5662 can be supplied with specialist microphone configurations for measurements beyond the standard 25–140 dB(A) range.
High SPL
Measurement range:
