  "textContent": "Disclosed are a method and apparatus for controlling an inverter of an eco-friendly vehicle, which may generate noise outside of a frequency band audible to infants in a protection mode. The control method includes calculating a current noise frequency, determining whether the current noise frequency is higher than a target noise frequency, and changing a current inverter switching frequency based on the real-time motor rotation frequency to generate noise corresponding to the target noise frequency when the current noise frequency is lower than the target noise frequency. Accordingly, it may be possible to prevent noise generated when the eco-friendly vehicle is driven from affecting the sense of hearing of an infant in the vehicle, whose audible frequency band is higher than that of an adult, thereby preventing hearing loss of the infant.",
