Why Choose the Professional Class 1 Kit?
This kit is designed for users who require more than a basic sound level reading.
The AWA5662 Statistical configuration measures conventional integrating parameters such as Leq while also providing statistical Ln measurements, time-history logging and audio recording.
Statistical analysis is particularly valuable when noise varies over time and a single average level does not provide the complete picture.
The included Class 1 calibrator allows field verification before and after a survey, while the tripod provides consistent positioning during professional measurements.
Suitable for:
- Environmental consultants
- Acoustic consultants
- Occupational hygienists
- Health and safety professionals
- Industrial facilities
- Engineering companies
- Environmental officers
- Universities and research facilities
- Professional testing organisations
AWA5662 Statistical Class 1 Sound Level Meter
The AWA5662 is a professional IEC Class 1 sound level meter designed for environmental, workplace and industrial noise measurement.
The Statistical configuration supplied in this kit includes:
- Integrating Leq / Peak measurement
- Statistical Ln analysis
- Time-history data logging
- Audio recording
- 4 GB internal memory
- Support for up to 64 GB TF card
- Bluetooth communication
- USB data connection
Main Measurements
Measurement capabilities include:
- Lp
- Leq
- Lmax
- Lmin
- SEL
- Peak sound levels
- Statistical Ln values
- Time-history measurement data
Statistical Noise Analysis
Environmental noise often changes considerably throughout a measurement period.
Statistical Ln measurements show the sound level exceeded for a specified percentage of the measurement period and provide additional information beyond a single Leq value.
Common statistical parameters such as L10, L50 and L90 can help characterise:
- Background noise
- Typical ambient noise
- Intermittent noise events
- Traffic noise
- Community noise
- Industrial noise
- Changing environmental noise conditions
This makes the AWA5662 Statistical configuration particularly suitable for professional environmental and community noise surveys.
Time-History Data Logging
The AWA5662 records measurement data over time, allowing the user to review how noise conditions changed during the survey.
This is useful for:
- Long-duration environmental measurements
- Traffic noise surveys
- Industrial boundary measurements
- Machinery operating cycles
- Construction noise
- Intermittent noise events
- Workplace investigations
Stored measurement data can be transferred to a computer for further review and analysis.
Audio Recording
The Statistical configuration also provides audio recording capability.
Audio recording is useful when measurement data shows a significant noise event and the user needs additional information to identify its likely source.
Typical applications include:
- Noise complaint investigations
- Environmental surveys
- Construction noise
- Community noise
- Machinery investigations
- Intermittent industrial noise

AWA6021A Class 1 Sound Calibrator
The included AWA6021A provides Class 1 field calibration and verification of the sound level meter.
The calibrator complies with IEC 60942:2017 Class 1 and provides two selectable calibration levels:
- 94 dB @ 1 kHz
- 114 dB @ 1 kHz
Sound pressure level accuracy is ±0.25 dB.
The AWA6021A also incorporates automatic atmospheric pressure compensation to help maintain stable output under changing field conditions.
A field calibration check can be performed before and after a professional noise survey to verify that the measurement system has remained stable.
AWA8814 Professional Tripod
The included AWA8814 professional tripod provides stable and repeatable positioning during noise measurements.
Using a tripod helps:
- Maintain consistent measurement height and position
- Reduce movement during measurements
- Reduce handling of the instrument
- Improve repeatability between surveys
- Support longer-duration measurements
- Provide a stable setup for environmental field work
Data Storage & Transfer
The AWA5662 Statistical configuration provides substantial storage for professional measurements.
- 4 GB internal memory
- Support for up to 64 GB TF card
- Time-history measurement storage
- Audio recording
- USB data transfer
- Bluetooth communication
This allows large amounts of measurement information to be stored in the field and transferred for later analysis.
Typical Applications
- Environmental noise surveys
- Community noise assessment
- Traffic noise
- Industrial boundary noise
- Factory noise
- Construction noise
- Workplace noise surveys
- Machinery and equipment noise
- Occupational hygiene
- Noise complaint investigations
- Long-duration noise measurements
- Professional acoustic consulting
- Engineering noise investigations
- Environmental compliance surveys
- Research and education
Need Frequency Analysis?
This kit is designed primarily for Class 1 integrating and statistical noise measurement.
If you also need to determine which frequency bands are contributing to the measured noise, consider the AWA6228+ Advanced Class 1 Noise Analysis Kit, which adds real-time 1/1 octave frequency analysis and a remote microphone measurement system.
The AWA5662 itself can also be supplied in configurations with 1/1 and 1/3 octave analysis where a more compact frequency-analysis solution is preferred.
