Listening to car radio or audio may be difficult or annoying when engine sounds interfere as the speed of the car increases. However, Speed-sensitive volume controls eliminates that problem by adjusting the volume to the speed.


Speed-sensitive volume control, also known as SVC, refers to car audio. It fixes the problem of having to manually turn up radio or audio volume as the car noise increases.


As the speed of the car increases, SVC automatically increases the volume of music or radio if it is turned on. It works to compensate for the noise of the engine and of the car on the road. As the speed of the car decreases, the volume decreases as well automatically.


Certain car models have SVC built into their audio system. This feature may be called Noise Sensitivity or Noise Sensitive Volume Control, or the car may be listed as being Speed-Sensitive. Cars that have this feature are Hondas, Hyundais and BMWs.
