AWA5920 Wearable Personal Noise Dosimeter

The AWA5920 is a compact wearable noise dosimeter designed for professional occupational and personal noise exposure assessment.

Worn directly by the worker, the AWA5920 measures noise exposure throughout a shift and calculates key parameters including TWA, LEX,8h, LAVG, Dose, SEL and Leq. It also provides statistical analysis, data logging and audio recording, with optional 1/1 and 1/3 octave analysis for more detailed investigation of workplace noise.

With up to 64 GB storage, more than 41 hours battery life and IP65 protection, the AWA5920 is suited to occupational hygienists, health and safety professionals and organisations carrying out workplace noise exposure surveys.

Choose Your AWA5920 Configuration

Configuration	Best For	Main Capability
Option 1 – Single Kit	Standard personal and occupational noise exposure surveys	TWA/Dose • Leq/Peak • Statistical Ln • Logging • Recording
Option 2 – Single Kit + Octave Analysis	Detailed individual exposure and frequency investigation	Standard functions + 1/1 & 1/3 Octave
Option 3 – 5-Pack	Monitoring multiple workers during the same survey	Five-dosimeter professional monitoring package
Option 4 – 5-Pack + Class 2 Calibrator	Multi-worker surveys with field calibration capability	Five-dosimeter package + Class 2 acoustic calibrator
Option 5 – 5-Pack + Octave Analysis + Calibrator	Advanced multi-worker occupational noise surveys	Five dosimeters + 1/1 & 1/3 Octave + Class 2 calibrator

These five configurations correspond directly to the packages in Aihua's current 2026 price list. All include Leq/Peak, Ln statistics, TWA/Dose, logging, storage and recording; octave analysis is included in Options 2 and 5, while a sound calibrator is included in Options 4 and 5.

Option 1 – Single Kit

The standard choice for individual workplace noise exposure measurement.

The worker wears the compact AWA5920 throughout the measurement period while the instrument continuously records and calculates occupational noise exposure.

Measurements include:

• TWA
• LEX,8h
• LAVG
• Noise Dose
• Personal sound exposure
• Leq
• Peak levels
• Statistical Ln values
• Data logging
• Audio recording

Ideal for routine occupational hygiene and workplace noise surveys.

Option 2 – Single Kit + Octave Analysis

Adds real-time 1/1 and 1/3 octave frequency analysis to the standard dosimeter functions.

This is useful where it is not enough to establish how much noise a worker is exposed to — you also need to determine which frequencies are responsible for that exposure.

Ideal for:

• Engineering noise control
• Hearing-protection investigations
• Machinery noise
• Noise-source identification
• Detailed occupational hygiene surveys

Option 3 – 5-Pack

Designed for surveys where multiple employees or work positions need to be monitored simultaneously.

A five-dosimeter system allows exposure measurements to be collected from multiple workers during the same shift, making it particularly useful for larger occupational hygiene programmes.

Option 4 – 5-Pack + Class 2 Calibrator

Adds a Class 2 acoustic calibrator to the multi-instrument system, allowing the dosimeters to be field checked before and after measurements.

The supplier's five-pack calibrator kit includes five AWA5920 dosimeters, one sound calibrator and a five-unit charging dock with power supply.

Option 5 – 5-Pack + Octave Analysis + Calibrator

The most comprehensive AWA5920 package.

It combines:

• Five wearable dosimeters
• Leq / Peak and statistical analysis
• TWA / Dose measurement
• Data logging
• Audio recording
• 1/1 octave analysis
• 1/3 octave analysis
• Class 2 sound calibrator

Ideal for professional occupational hygiene teams carrying out advanced multi-worker exposure surveys.

Occupational Noise Measurement

The AWA5920 measures the key parameters required for personal noise exposure assessment.

Parameter	Measurement
TWA	Time-weighted average sound pressure level
LEX,8h	8-hour equivalent sound pressure level
LAVG	Average sound pressure level
DOSE	Noise dose percentage
E	Personal sound exposure
SEL	Sound Exposure Level
Leq,T	Equivalent continuous sound level
Lpeak	Peak sound pressure level
Ln	Statistical percentile noise levels

Exchange rate can be selected from 2, 3, 4, 5 or 6, with selectable threshold levels from 40–90 dB and criterion levels from 70–90 dB.

Octave Analysis

Optional Class 2 frequency analysis provides both:

1/1 Octave

Nine bands from:

31.5 Hz to 8 kHz

1/3 Octave

Detailed frequency analysis from:

20 Hz to 12.5 kHz

Both modes provide real-time Lp, Lmax, Lmin and Leq,T measurements with simultaneous A, C and Z weighted analysis.

Data Logging & Audio Recording

The AWA5920 includes 64 GB storage and can save measurement results for later PC analysis.

Audio recording is stored in WAV format with selectable recording quality up to 48 kHz / 32 bit, allowing recorded noise events to be reviewed after the survey.

Measurement data can be transferred directly to a computer using the USB Type-C interface.
