PURPOSE: An apparatus for visualizing sound field is provided to improve measurement reliability and to have no influence on the reflection of sound signals and the damping of data by optimizing the properties and measurement environments of multi-channel sensors. CONSTITUTION: An apparatus for visualizing sound field comprise a spherical body(10) and a MEMS microphone(12). The spherical body has multiple through-holes. The MEMS microphone is inserted and fixed through the through-holes and is arranged on the spherical body to match a noise measured surface and the spherical surface of the spherical body. |
