noise meter

[EdT]

Anyone in the Reading area got a noise meter? Would like to be confident I wont lose my deposit when booking a Thruxton day later this year!

I got one. Needs some batteries tho.

I am in Wokingham

Got a box of various sizes, all rechargeable. What does it take? Or could raid one of my various RCs in the lounge.

hmmm...

90db(A) static noise limit (measured at 45 degrees to exhaust from 0.5 metres at 2/3rds of max RPM


I wonder..seems quite low to me.

If weather's OK I'll take the 500 into work (Bracknell).. will keep an eye on this thread. If not happy to pop over somewhere early evening asap

[EdT]

Any chance during a day.. perhaps a lunchtime shandy & little blast around ?!

Fantastico. As long as it's not -3C degrees as it is this morning I'll use the 500 this Wednesday.. can meet half way or something

I'm sure I can manage that, Wednesday might be easy for me at the moment, I work over in maidenhead so it's only a short run to get over to brackell along so roads I rather like

oops do I dont! Just realised since changing web companies I've not setup that email address.
Let me have a tinker...

(edited: Ben could you resend please.. have update PH profile with a working address)

Well I didn't see the post when we were taking a look, but Ed it might not be that bad. I didn't see your point about it being A-weighted and the readings of 99 at idle and around 108-110 at 2/3 was with c-weighting. Give us a shout if you want me to pop by again, however I still think it'll be too loud.

Ben you've lost me ! (bit like the M4 jsut now... oops sorry!)

Well there's two frequency ranges that the meters can be weighted to measure, I didn't remember your post until just after you'd driven off (I had a look) but I'm taking a stab it should have been A-Weighted not C-Weighted as it was set when we had a go.

This page explains some of it, it *might* make a differnce for the better or worse.

well we should probably have a 2nd blast then ?!

Spoke to helpful fella at Thruxton & it sounds like a no no. However the limit at Castle Combe in 100db so this might be possible with something like this :

They're are in the circuit which is handy.. can test the noise etc.

A pal has previously made mutes for his vintage bikes.. gonna have a chat to him also

[EdT]

what are the internals you mention.. main baffles?

No, just shove 'em down the exhaust pipes, which should be the same as your Griff?

Where are you based, you can pop round and have a go - i am just round the corner from Ben's house, so if you speak nicely to him, you could get a definite read with the various conbinations of silencers.

HTH

I'm about 5 mins from M4 junction 12
