Firms Working In Acoustic Consulting

Unranked roundup — fewer than 8 firms have enough eligible activity in this window to hold a rank, so a ranking would be a false signal. Listed alphabetically instead.

Score = 1.0 per eligible project completed this year or last, 0.75 for 2–3 years ago, 0.5 for 4–5 years ago, +0.1 per independently-sourced project (capped at +0.5/firm). Eligible: status: completed projects with year_completed in the trailing 5 years. Ties broken by most recent status_verified date. See About for the full methodology.

Counts reflect the work this index has recorded, not a census of any firm's total output — coverage depth varies by firm — and a position here implies no judgment of design quality.
