Know before the spec is locked, not after the client complains.
Acoustics is usually the thing that gets discovered post-occupancy — after the hard floor, glazed partitions and bare ceiling are already built, when changing them means a second fit-out instead of a line in the original spec. Echo moves that discovery earlier, to whichever stage you're actually making the decision.
At concept
Model the room from the brief's dimensions before a single finish is chosen, so acoustics is one of the inputs to the material palette rather than a constraint discovered afterwards.
At detailed design
Import the actual room geometry from a DXF plan, check the specified finishes against the standard the room type needs to meet, and see exactly which surface — and how much of it — closes the gap if it doesn't.
At client sign-off
Hand over a branded report with the figures and the standard they're checked against, so "we considered acoustics" is something you can evidence, not just assert.
Where this fits against a full acoustic consultant
It doesn't replace one, and for anything contentious, contractual, or where a signed-off figure is genuinely required, you still need to appoint one. What Echo replaces is the uncertainty before that appointment — the rooms where the honest answer is "this is fine, don't spend the fee", found in sixty seconds instead of a fortnight, and the rooms where the answer is "this genuinely needs a specialist", found early enough that a consultant is a planned cost rather than a late one.
