Handheld sound level meter supplier for noise measurement

AWA5688Aihua handheld sound level meterAs a high-performance noise measurement device, its differentiated advantage among similar products lies in the combination of Type 1 accuracy (± 0.7dB) and multitasking capabilities. Its parallel measurement architecture improves measurement efficiency by about 60% compared to traditional serial processing devices, making it particularly suitable for complex noise scene analysis that requires simultaneous acquisition of time-domain and frequency-domain parameters.

1AWA5688Aihua handheld sound level meterCore technological advantages:

Digital signal processing technology:Adopting a new generation DSP chip, it supports real-time parallel processing of integral measurement, statistical analysis (such as Lmax, Leq), 1/1 octave spectrum analysis, and FFT high-resolution analysis, meeting international standards such as ISO 1996

Multi dimensional requirements for accurate noise measurement.

Modular architecture design:The functional components support on-demand expansion. The basic model comes standard with a total value integration and statistical analysis module, and can be optionally equipped with GPS geotagging (in compliance with IEC 61672 positioning record requirements), Bluetooth wireless transmission (supporting real-time data upload to cloud platforms), and a building acoustics special kit.

Compliance certification:Type evaluation certified by CNAS (Certificate 2015S554-33)

Execution standard:GB/T 3785.1-2023/IEC 61672-1:2013 Sound Level Meter Level 2 Standard GB/T 3241-2010/IEC 61260-1:2014 Filter Level 2 Standard

2、 Innovative functional design of AWA5688 multifunctional sound level meter:

Intelligent startup system:Supports three triggering modes (instant start/timed start/external signal trigger), with a built-in real-time clock that can achieve pre programmed measurement tasks within a 24-hour cycle, especially suitable for the construction of environmental noise automatic monitoring stations.

Personal voice exposure monitoring:Compliant with ISO 9612 occupational noise exposure assessment standard, equipped with an ergonomic stand, can be paired with a lavalier microphone for 8-hour continuous monitoring, and data storage interval can be set (1s-1h).

3、 Industry application solution for AWA5688 multifunctional sound level meter:

In the field of environmental monitoring:Equipped with the AWA8620 outdoor microphone kit, it meets the 24-hour continuous monitoring requirements for traffic noise and regional noise in GB 3096-2008 "Environmental Quality Standards for Noise".

Industrial diagnostic applications:The FFT analysis module supports a frequency range of 0.5Hz-20kHz and, combined with the machine noise feature database, can quickly identify abnormal frequency components such as bearing faults and gear wear in rotating machinery.

Architectural Acoustic Measurement:The optional sound intensity probe kit meets the GB/T 19889 series standards and is suitable for on-site testing of parameters such as sound insulation and absorption coefficient.

4、 Data management ecology of AWA5688 multifunctional sound level meter:

Equipped with AWASound software platform, supporting:

1. Automatically generate a report of measurement data in accordance with the HJ 640-2012 format of the Ministry of Environmental Protection

2. Export spectrum data to MATLAB compatible format

3. Realize on-site data visualization analysis through Bluetooth 4.0 and mobile terminal APP

4. The differentiated advantage of this device among similar products lies in its combination of Type 1 accuracy (± 0.7dB) and multitasking capabilities. Its parallel measurement architecture improves measurement efficiency by about 60% compared to traditional serial processing devices, making it particularly suitable for complex noise scene analysis that requires synchronous acquisition of time-domain and frequency-domain parameters.
