Stop acoustic nightmares before construction starts

Walks through the three points in a real design workflow Echo is built for: a fast check at concept stage, a DXF-import-driven check at detailed design, and a final figure to show a client at sign-off -- each with the same five fix options and exact surface areas.

Framed for architects specifically: works on a phone or iPad for a site visit, keeps an order record for 6 years (the report download link lasts three years from purchase, so save a copy anyway), and is explicit that it's a design-stage prediction tool, not a substitute for a consultant or a formal measured survey under BS EN ISO 3382-2 when a contractual figure is required.
