This service is tailored to manufacturers, R&D engineers, and contractors in the household appliance industry seeking accurate, reliable, and internationally accepted testing results.
About the standards: ISO 7779:2018 & ISO 3745:2012
ISO 7779:2018 – Measurement of airborne acoustical noise
This standard specifies the procedures for measuring and declaring noise levels of information technology and household appliances, including refrigerators. It defines how sound pressure levels should be measured at the user’s position and how to declare sound power levels based on standardized environments.
ISO 3745:2012 – Determination of sound power levels
ISO 3745 provides detailed methodologies for determining the sound power level of noise sources using precision-grade acoustic environments like anechoic or hemi-anechoic chambers. DASM complies with this standard to ensure measurement accuracy and comparability worldwide.

Refrigerator noise testing process overview
- Sample preparation
The refrigerator sample is installed under simulated usage conditions (powered, door closed, in cooling operation) and positioned within the anechoic chamber per ISO requirements.
- Measurement conditions
Measurements are conducted in a controlled acoustic environment. Microphones are placed in multiple positions around the appliance to record sound pressure levels. Data is processed to calculate A-weighted sound power levels (dBA).
- Reporting & compliance
After noise survey and evaluation, DASM provides a detailed test report that includes:
+ Sound power levels (dBA)
+ Sound pressure levels at operator/user position
+ Spectral data (frequency analysis)
+ Compliance assessment against ISO standards
Who should use DASM’s acoustic testing service?
+ Refrigerator and appliance manufacturers (quality assurance, R&D)
+ OEM suppliers seeking certification or export
+ Contractors working with global appliance brands
+ Product developers aiming for eco-design and silent operation
