Noise restrictions for trackday

Hi folks,

I'm heading over to Anglesey in Wales later this week to do a trackday. One of the rules is that the bike has to pass a 102dB static noise test. I've a set of Two Brothers cans on the bike and to be honest I have no idea how loud they are (though they do move pedestrians out of the way!).

Just in case, I'm seriously considering bringing the stock cans with me and if the bike fails fitting them on. Would be a bummer to go all the way to Wales and not be able to get on track. But I would much rather take to the track with the Two Brothers still fitted

So any way I can measure the noise levels of the bike myself? And what exactly does a static noise test entail?

All help n advice much appreciated!

I'm sure you can get a decibel meter app for your phone.
Snetterton tested me at 5500 rpm I was making 100 db with baffles in,they basically get you to hold a required rev range while measuring the noise. Soon as the test was done I took my baffles out.

You`ll find it`s a better class of people who own BMW motorcycles

Cheers John, I don't have baffles in the Two Brothers cans so I reckon they mightn't pass. Think I'll wrap up the stock cans and carry them with me on the bike - that way there's no risk of me missing out on track time...

I've had a look on Google play store (calm down Peter) and there are several decibel meters that are free,so why not download one and give it a whirl?

Well there was no checking of sound levels at all on the day. But apparently it's pot luck as sometimes an independent assessor is there to take readings and can stop you from going on track. Kind of ironic really as when the RAF boys flew their jet fighters overhead you couldn't hear the bikes at all, even when a bunch of them were passing the pit wall!!
