Wii is too loud

The volume on my TV runs on a scale of 0-100. When I watch cable, I set the TV at 50 and all is well. If I turn on my Wii, I have to turn the TV down to 10 or less before the Wii Menu’s chimes begin their droning and alarm the neighbors. My GameCube was similar, but Wii seems to be even louder.

Is it just me, or is the audio on Wii just too loud?
