AWA5662 Class 1 Professional Noise Measurement Kit

The AWA5662 Class 1 Professional Noise Measurement Kit provides a complete solution for professional environmental, workplace, industrial and consulting noise surveys.

Built around the AWA5662 Statistical Class 1 Sound Level Meter, the kit includes an AWA6021A Class 1 Sound Calibrator and AWA8814 professional tripod, giving users the essential equipment needed to measure, verify and document noise levels accurately in the field.

In addition to integrating measurements such as Leq, the Statistical configuration provides Ln percentile analysis, making the kit particularly suitable for environmental, community, traffic and industrial noise assessments.

Complete Class 1 Measurement Kit

Why Choose the Professional Class 1 Kit?

This kit is designed for users who require Class 1 accuracy and professional environmental measurement capability, but do not necessarily need advanced frequency analysis.

The AWA5662 Statistical configuration adds percentile noise statistics to conventional integrating measurement, while the included Class 1 calibrator and tripod provide the accessories normally required for professional field surveys.

It is an excellent choice for consultants, environmental practitioners, occupational hygienists and industrial users looking for a complete Class 1 system at a competitive price.

AWA5662 Statistical Class 1 Sound Level Meter

The AWA5662 provides professional IEC Class 1 measurement with a wide dynamic range and extensive logging capabilities.

The Statistical configuration combines integrating sound measurement with percentile noise analysis.

Main Measurements

• Lp
• Leq
• Lmax
• Lmin
• SEL
• Statistical Ln values
• Peak sound levels
• Measurement logging
• Audio recording

Why Statistical Analysis Matters

Environmental noise often changes significantly over time.

Statistical measurements such as L10, L50 and L90 provide more information than a single average noise level and can help distinguish between:

• Background noise
• Typical ambient noise
• Intermittent noise events
• Traffic noise
• Industrial noise sources

This makes the Statistical configuration particularly useful for environmental and community noise assessment.

Key Specifications

AWA6021A Class 1 Sound Calibrator

The included AWA6021A provides professional field verification of the sound level meter before and after measurements.

It provides selectable:

• 94 dB @ 1 kHz
• 114 dB @ 1 kHz

The AWA6021A complies with IEC 60942 Class 1 and provides a sound pressure level accuracy of ±0.25 dB.

Using a calibrator before and after a professional noise survey provides confirmation that the complete measurement chain has remained stable.

AWA8814 Professional Tripod

The included AWA8814 tripod provides stable positioning for environmental and longer-duration measurements.

A tripod helps:

• Maintain a consistent microphone position
• Reduce movement during measurement
• Keep the instrument away from the operator
• Reduce acoustic reflections from the operator's body
• Improve repeatability
• Support longer unattended measurements

Typical Applications

• Environmental noise surveys
• Community noise assessments
• Traffic noise
• Industrial boundary noise
• Factory noise
• Workplace noise surveys
• Construction noise
• Machinery and equipment noise
• Occupational hygiene
• Noise complaints
• Professional acoustic consulting
• Engineering noise investigations

Who Is This Kit For?

The AWA5662 Professional Kit is particularly suited to:

• Acoustic consultants
• Environmental consultants
• Occupational hygienists
• Health & safety professionals
• Industrial facilities
• Engineering companies
• Local authorities
• Universities and research facilities
• Professional testing organisations

Need Frequency Analysis?

This kit is designed primarily for professional Class 1 sound level and statistical noise measurement.

If you need to identify which frequencies are causing the noise, consider the AWA6228+ Advanced Class 1 Noise Analysis Kit, which adds octave frequency analysis and a remote microphone extension cable.

The standalone AWA5662 can also be supplied with 1/1 and 1/3 octave configurations where required.
