PROBLEM TO BE SOLVED: To provide a noise/vibration level display method capable of visibly displaying a maximum value and a minimum value of a noise level or a vibration level and fluctuation width of an instantaneous value easily recognizably. SOLUTION: In this noise level display method in a noise meter, the maximum value Lmax and the minimum value Lmin of the noise level measured by a sampling period T within a measurement time t are indicated in a horizontal bar graph, while the width D of the maximum value Lmax and the minimum value Lmin is clearly indicated on the horizontal bar graph. The instantaneous value Lp of the noise level is also indicated on the horizontal bar graph. COPYRIGHT: (C)2004,JPO
