APPARATUS AND METHOD FOR MEASURING NOISE |
| 摘要 |
An apparatus for measuring noise includes: a signal generator configured to input an input signal having an excitation frequency to an audio device; and a controller configured to measure rattle noise from a sound pressure signal generated in response to the input signal. The controller measures the rattle noise by comparing a frequency component of the sound pressure signal with a masking curve corresponding to the excitation frequency. |
