Erecting a secondary acoustic fence one meter from my boundary

Hi I would like to erect a fence one meter from my garden boundary on my land ( in my garden)this dose not border any neighbour 
we live next to a busy Rd and want to put up a 8ft /10ft acoustic fence
this would be 5 meters from the public footpath or highway 
there are also tall cherry bay shrubs on the other side of my boundary fence in on common land 
so you wouldn’t be able to see the new secondary fence from the public path highway 
hope this all makes sense

    Hi @jamie7950 ,  You probably need to ask for advice/guidance from your local planning department as the height you want is over the permitted  2 m fence height.

    It would be a very expensive project if you got told to remove it at a later date.

    Have you considered whether the new fence height might cast a lot of shade?

    At the moment we have 5 meter high laurel bushes on the perimeter of the garden out of control 
    we are planning to put the fence between the laurels and the original fence boundary which is the 2 meters permitted 
    The fence wouldn’t be seen from the garden or from the highway

    Ok so what is your actual question about?

    Even an internal fence [which is what you intend having] several yards in from a boundary, can have height restrictions, so it would be wise to check before going ahead. 
    I'm slightly confused by the fact you have an existing fence on the boundary, but want the new one between the laurel and that one, and you say the laurel's on the perimeter, and on common land. If the new fence was on common land - ie outwith your current boundary fence, that wouldn't be allowed.

    Are you asking whether the fence would work?

    Ok how tall can I make the fence 
    I know 2 meters is permitted on a boundary 
    but this is set back from the boundary by 1-2 even 3 meters space is not the issue it’s noise 👍

    You'd really have to contact the council to check their rules and regs. I have a feeling the height rule still applies, even if it's several yards inside the boundary, but it may depend on the area you're in.
    I don't know how effective these things really are at mitigating noise though. I think the laurel hedging would be more effective at dissipating noise.

    1m roadside, 2m away. Anything else needs planning permission. Those permitted development rights will be withdrawn for e.g. conservation area

    Have you been to many homes that have the kind of fence you are suggesting, near a major road?  I strongly suspect they might not have the effect you are hoping for. I would do visits and a lot of research before shelling out on the project. You should know exactly what you are paying for and what realistic results to expect.

    Firstly a 3m solid fence is a large structure..even if it is permitted. How do intend to build it?
    How much attenuation do you want?
    Designing an acoustic barrier needs a lot more data than "I'll just build a fence"
    Let's make some assumptions..you're 10m away from the source which is 100dB. 
    You build a 3m solid barrier in the middle.. 5m from the source ..5m from you.
    You can expect a reduce that 100dB to about 67dB. (Traffic noise tends to be multi spectrum frequency..a single frequency source would lower that figure to 58dB).
    A 2m barrier would reduce it to 70dB. (Note that the dB scale is logarithmic).
    Is that enough?.
    The hedge will give you almost no attenuation..well some...but barely noticeable.
