The near field is a sound field within a distance of twice as long. The longest wavelength of the sound wave (that is, when the frequency is 20Hz) is 17 meters. Therefore, for the entire audio range, the sound field of less than 34 meters is a near field and a near field room. Known as a small room, in the case of near field, the sound will interfere, and there will be Fresnel sound interference area in the sound field.
