If you drive an Actros you would never touch the horn button unless there were some nice boys about with hearing aids.
Me too, you press it in anger and people are looking around for a scooter or something. I hate it when kids are on bridges asking for you to give them the air horns! Mercedes should be ashamed of themselves! Even when reversing in yards and you toot on the horn to warn people they scratch their heads wandering where that noise came from. 
when i was an apprentice in a hgv bodyshop a norfolk line drive had some train horns fitted to his unit we fitted em and had to test em you could only fit 2 units and trailers in at any 1 time and the offices were right next door anyway we let them rip a few time all having a good laugh only for a big boss to storm in goin off his tree 
turns out when we tested em they were that loud the receptionist ■■■■ herself and spilt a cup of tea all over her lap 
Have to agree the actros horn ■■■■ balls, im back in the XF and it makes me feel more like a man, funny how the horn makes you feel.
I feel the OP pain though, a car full of totty laughing at you would be painful, I wouldn’t of given them a honk with a crappy horn but more like a Keith Lemon mot mot mot impression.
Some of the stories in this thread had me in tears
So it seems that size does indeed matter. We all want a bigger horn and the lucky few who already have a massive horn wouldn’t swap it for a tiny one. I can’t wait until I get a big horn, the first pretty girl who wants it is going to get a really long, hard press of it.
Great thread. What’s perhaps not so embarrassing, as hopefully no-one else notices since no sound at all is emitted, is when someone cuts you up when you’re in an unfamiliar truck and all you can do is wash the windscreen.
i drive an actros an it has air horns on the roof that sound very similar to these
We have a few with decent horns, but most are like a Road Runner cartoon and I don’t mean the Acme TNT !!
One does have horns like a freight train and I must admit I have actually phoned friends and family just to have a listen 
I even did a detour on the way back to the yard to go past my house to give the missus a blast, she was on the phone to my mam at the time and even she said “chuffin hell what was that?” 
I love having a huge horn
I was at roundabout when a transit full of workers pulled along side me and one guy was asleep so I thought that’s not fair and gave him a little alarm call 
let’s just say his mates found it much more amusing than he did, they all gave me the thumbs up, I won’t say which digit he raised

Thats the advantage of having a huge horn when you see someone having a snooze in the passenger seat as they trundle past,you can’t help yourself,well I can’t anyway
The scowl followed by the finger is well worth it. 
I feel for your inadequacy in the “■■■■■” department, personally I’ve never suffered from this ( not that I would admit it even if I did ) but as always I have a friend or two that have. As for the size I thinks thats a personal choice, remember though what most young girls and older women say “it’s not always the size but the blast behind it” that matters and knowing how and when to use it. A large one’s blast can sometimes be over in seconds but a small one in the right hands can be noisy for a good minute or so and bring them real enjoyment. I know through enquiring for my afore metioned friends that there are no tablet solutions for your problem but you can now get a " horn extension " if you feel you own is to small and embarrassing, these come in various different sizes and you can have it on permant show or discretely hidden from view so that these young ladies know nothing about your extension.
Here are a couple of places that can perform your horn extension, I hope they are of help
