Why ads sound louder.Technical answer, dynamic range and compression.Imagine a movie where the character whispers quietly, then begins talking, then starts shouting.Broadcast dynamic range ensures that you can hear what's said during the whispering, but ensures your TV sound doesn't distort when the shouting begins.For ads, the sound is 'compressed' so that almost every word/sound is broadcast at what would normally be the 'shouting' level in a movie. Result, you hear every word spoken, even if you're not in the room, and you walk like a robot to your local store to buy, buy, buy.
