The sound carrier is 10 to 15 db below the video carrier and does not change between programing and commercials.
Tallest hump is video carrier, second is color burst and last is sound carrier.
The loudness not determined by the db level of the carrier but by the deviation, how much it shakes.
Okay this is not an audio carrier but it is a great image to explain by. If it were an audio carrier and it looked like this it would be loud and normal would be half as wide. The height don't matter for loudness, just tunning.
The promised not to mess with the carrier level or height.
