The AWA6228+ Advanced Class 1 Noise Analysis Kit is a complete professional system for environmental noise surveys, engineering investigations, machinery noise analysis and acoustic troubleshooting.

Built around the AWA6228+ Class 1 Sound Level Analyzer with frequency analysis, the kit combines integrating and statistical noise measurement, data logging and real-time 1/1 octave analysis with a Class 1 acoustic calibrator, tripod and remote microphone system.

It is designed for professional users who need to do more than simply measure how loud a noise is — the AWA6228+ can also help determine which frequency bands are contributing to the noise.

Complete Advanced Class 1 Kit

Why Choose the Advanced Kit?

This kit is intended for applications where overall sound level alone doesn't tell the full story.

A conventional sound level meter can establish that a noise problem exists.

The AWA6228+ adds frequency analysis, allowing the user to investigate where that noise sits within the frequency spectrum.

This is particularly valuable when:

• Identifying machinery noise sources
• Investigating tonal noise
• Selecting noise-control measures
• Investigating low-frequency noise
• Comparing equipment
• Assessing environmental noise
• Troubleshooting acoustic problems

The tripod, microphone holder and extension cable also allow the measurement microphone to be positioned independently of the operator and instrument.

AWA6228+ Class 1 Sound Level Analyzer

The AWA6228+ is a configurable Class 1 professional acoustic measurement platform.

The configuration supplied in this kit includes:

• Integrating sound level measurement
• Statistical noise analysis
• Data logging / time history
• 1/1 octave real-time frequency analysis

Main Measurements

• Lp
• Leq
• Lmax
• Lmin
• SEL
• Statistical Ln values
• Peak sound levels
• Time-history data
• Real-time octave-band levels

1/1 Octave Frequency Analysis

The included octave analysis divides the measured sound into individual frequency bands.

This helps determine whether a noise problem is dominated by:

• Low-frequency rumble
• Machinery frequencies
• Mid-frequency process noise
• High-frequency components
• Particular octave bands

This information is particularly useful when designing or selecting:

• Acoustic enclosures
• Barriers
• Silencers
• Absorption materials
• Hearing protection
• Engineering noise controls

Key Specifications

AWA6021A Class 1 Sound Calibrator

The included AWA6021A provides Class 1 field calibration and verification of the complete measurement chain.

Selectable calibration levels:

• 94 dB @ 1 kHz
• 114 dB @ 1 kHz

A field calibration check can be performed before and after a survey to verify measurement stability.

Remote Microphone Measurement

One of the major differences between this kit and the simpler professional kits is the included remote microphone setup.

The system includes:

• AWA8814 Tripod
• AWA8820 Microphone Holder
• AWA8732 5 m Extension Cable

This allows the microphone to be mounted on the tripod while the sound level analyzer remains with the operator.

Advantages

• Keeps the operator away from the microphone
• Reduces acoustic reflections from the operator
• Allows accurate microphone positioning
• Makes the display easier to operate during measurement
• Ideal for longer environmental surveys
• Improves consistency between measurements

Typical Applications

• Professional environmental noise surveys
• Industrial boundary noise
• Machinery noise investigations
• Engineering noise control
• Noise-source identification
• Frequency analysis
• Tonal noise investigation
• Construction noise
• Traffic and community noise
• Factory noise
• Acoustic consulting
• Product noise measurement
• Environmental compliance surveys
• Long-duration monitoring
• Research and development

Advanced Functions Available

The AWA6228+ can be expanded beyond the functions included in this kit.

Optional analysis functions include:

These can be specified separately where the application requires them.

Who Is This Kit For?

The AWA6228+ Advanced Kit is particularly suited to:

• Acoustic consultants
• Environmental consultants
• Noise-control engineers
• Industrial hygienists
• Mechanical engineers
• Environmental officers
• Research laboratories
• Universities
• Product development teams
• Professional testing organisations
