Sound Quality Evaluation of Cabin Noise Onboard Ships
Due to the difficulty in effectively reflecting human subjective feelings in existing ship noise evaluation technical standards,the study on the sound quality evaluation technology of ship noise based on human subjective feelings is conducted.Based on ship noise data measured onboard,the mathematical model between subjective comfort evaluation indicators and psychological acoustic indicators through subjective evaluation experiments is obtained.A systematic method for evaluating the sound quality of ship noise is established.Based on the comfort requirements of different groups for different compartments onboard the ship,subjective perception-based limits for controlling the sound quality of ship noise has been established.This study has application value and significance in improving the level of noise design and control onboard ships,enhancing personnel comfort.
