Attenuators / Silencers - Main, Cross Talk

device/asset description
Attenuators / Silencers - Ventilation Plant
Attenuators / Silencers - Cross Talk

device/asset name
ATT
CTA

I note that the current general abbreviation for is SLCR for silencer which does not allow easy separation of the key types and is also not really typical of my experience of language in UK market. Happy to be corrected but Silencer is more US language, ATT and Attenuator is more common in UK to my me.

Adding the ventilation plan and cross talk would be ok - further discussion first about general abbreviation 'SLCR'

@Richard-Jackson-Arup
Could the asset type help in this case, to differentiate the attenuator types?

I don't think that works very well as it is unclear to casual reader what the type referencing means in this case.

I can see me using maybe the type referencing to cover system type a lot if/when I want to include that and the fact that is slightly impenetrable is not so much of an issue because the person who needs to know what that means will.

I this case it is pretty basic differentiation to make the system easier and more coherent to use.

I think the terms ATT and CTA are also pretty widely used. Seems a strange one to not just do given the degree of granularity already provide for a lot of other items.

What about the SLCR vs ATT? I might ask around Mech teams beyond my own, see what people are doing in case it is just me being obtuse.

@jgunstone @pisuke

Any further thoughts on the above? It is a fair point.

I asked our acoustics team and for them being able to use ATT instead of SLCR is very important.
I also agree having CTA is useful

[Richard-Jackson-Arup]

Hi John, thanks for this.

For clarity your acoustic team they prefer ATT over SLCR? That is my preference too but what was the reasoning (for me it is a preference based on what I perceive as "normal" in UK market, as opposed to going as far as "very important". Be interesting to understand the perspective.

[jgunstone]

Hi -
yes ATT not SLCR.
and yes basically the same reasoning - I think whilst Silencer (SLCR) also makes sense it is scarcely used in a UK market and goes against the norms that they have established over many years of operation.

perhaps I'm overstating their opinion... but they seemed to feel pretty strongly about it!
