1. Loud weights being dropped / gavels hitting blocks/ the sound of metal clanking:
Giving us a headache every half second in between what you're trying to say generally isn't a great way to keep people interested. Unless you're trying to sell ibuprofen.
2. Police sirens or the sound of alarms going off:
Your sale might be so good it's criminal, but every time I hear police sirens, I have to do a double take and make sure there's not actually a police officer nearby trying to pass through traffic.
3. When the GM/CEO of a company voices every commercial in the same repetitive, monotone way:
It's good to be consistent. It's not so good to be dull to the point of inducing yawns. In the internet world, it is the equivalent of a wall of text, akin to the thought of Ben Stein reading a short novel to you while you're locked in an empty room. This is the kind of stuff that puts you asleep at the wheel, and as we know, drowsy driving is never fun.
4. Mentioning the number you should call more than a few times:
The way this usually works is, it'll be a conversation between two or more people, and some guy will keep asking what the number to call is. We're not just talking once or twice, it'll literally be every few seconds. These types of commercials are usually guilty of #3 as well. What's that number again?!
5. Jingles designed to specifically get on your nerves:
I have nothing against La Bamba. It's a catchy song. But when you try to mimic it or parody it by adding in your own lyrics to tell people to come to your business, it usually doesn't end well. Imagine the song, then imagine instead of "La La La La La Bamba", you hear an awkward voice singing "You should be buying from us!"
What sounds or effects drive you crazy when you hear radio commercials in the car? Or do you skip 'em by using satellite radio or iHeartRadio with Entune?
