APPARATUS FOR MEASURING DUCT NOISE

摘要

The present invention relates to a device for measuring the level of noise by driving a speaker (10) and a fan (15). The present invention comprises: a duct (20) with multiple openings (22) to mount the speaker (10); a cover (30) to open or close the openings (22) of the duct (20); and a measuring unit (40) for extracting and displaying noise, installed on the inside of the duct (20). Therefore, by installing the speaker on the outside of the duct and sending the noise to the inside, a flow field by the fan is evenly formed, thereby improving the accuracy of the measurement.
