This fan is rated at 55 decibels on low and 65 decibels on high (it has two speeds). Keep in mind that there is no standard of measurement from one brand to another for decibel outputs. One manufacturer may take their readings right at the source while another may measure the sound at a distance. While a decibel rating can be helpful in comparing different units by the same manufacturer, those specs may prove to be inaccurate or misleading when comparing products from different brands.
