Can garage refuse MOT for hooter not loud enough when Honda had checked it recently and passed as ok?

Did they 'check' it to MoT standards?

The MoT tester is the one who passes or fails an issue so what Honda say is largely irrelevant.

Beauty is in the eye of the beholder, so they say.

A number of things in the MOT are "the opinion of the tester"

Get another horn £5 to £10 from a local accessory shop or ebay etc . . .

or one of these

The short answer is yes.

The MOT tester can tell the Honda guy he is wrong.

The Honda guy can tell you anything he likes - but has to accept what the tester says. It's an opinion/judgement as there is no noise testing equipment other than the tester's ears.

New horn needed I think.

Scrap yard visit would be the most economical unless you can get a free replacement from Honda.

As above, the test is loud enough to be heard by another road user - in the opinion of the NT.
Incidentally the performance of most horns that work a bit can be quite spectacularly improved by cleaning up the connections and the earths to them.

The MOT standard is simple, but does involve "tester's opinion".

Reason for rejection...
"The horn: b. is not loud enough to be heard by another road user"

If not the testers opinion, how would they decide if the horn was (or wasn't) loud enough? Do you think they use some type of noise measurement device?

Well they could use a sound level meter, but given there is no set standard for how loud a horn should be there wouldn't be much point. It's refreshing to see some things are still left up to common sense.
