It finds ceiling and wall absorbers, baffles, rafts, panels and screens by type, manufacturer, material, mounting, weighted absorption coefficient (alpha_w), fire class, build-up depth or EPD, proposes how much of a product the room needs and recalculates the room with it. Every value comes from an ISO 354 reverberation room measurement with a named test report; where the catalog has no measured value, the app says so instead of estimating. Fire classes are checked strictly to EN 13501-1 including smoke and droplet classes.\n\nNo account is needed to calculate rooms, find products or look up targets; the cards stay small and the answer stays in the conversation. When you want to keep a room, your Acoustic Index account saves it under the project of its building or client, opens it in the calculator in your browser, exports a branded PDF report and shares it with a link that works without an account. Measured values per octave band and variant also use the account.\n\nBuilt for architects, interior designers and acoustic consultants.\n\nLimitations: the app covers room acoustics (sound absorption and reverberation time), not sound insulation between rooms. Values are calculated with Sabine's formula from catalog data and do not replace a measurement or an acoustic consultant's design. The app sells nothing and cannot delete rooms; that is done in the Acoustic Index account.","plugin_category_id":"productivity","privacy_policy_url":"https://acousticindex.com/en/datenschutz","screenshot_urls":["https://files.openai.com/content?id=file_0000000081908246ac74581548437942","https://files.openai.com/content?id=file_00000000af3c81f4b9514e2cfe35f1c6","https://files.openai.com/content?id=file_00000000eda081f495bee061de0410aa","https://files.openai.com/content?id=file_0000000039e481f4923b64d688c4a108"],"short_description":"Room acoustics and absorbers","terms_of_service_url":"https://acousticindex.com/en/agb","website_url":"https://acousticindex.com"},"keywords":["acoustics","room acoustics","reverberation time","sound absorption","DIN 18041","architecture","interior design"],"onboarding_skill_name":null,"requires_local_executor":false,"skills":[],"version":"1.1.0"},"scope":"GLOBAL","status":"ENABLED"},"research":null,"package_metadata":{"name":"acoustic-index","author":{"url":"https://acousticindex.com","name":"Acoustic Index"},"sources":[{"path":"plugin.json","sha256":"26e8b1ccde856a44184880954052ffd77cad0b55b76c490b72230a6bfd4eb947"}],"version":"1.1.0","commerce":false,"homepage":"https://acousticindex.com/api/mcp","keywords":["acoustics","room acoustics","reverberation time","sound absorption","DIN 18041","architecture","interior design"],"artifact_id":138354,"observed_at":"2026-11-03T19:06:17Z","support_url":"https://acousticindex.com/en/contact","capabilities":["Calculate reverberation time against DIN 18041 and other standards, no account needed","Look up the target reverberation time of a standard for a room","Search acoustic products with lab-measured absorption","Propose product quantities that reach the target","Save rooms to your Acoustic Index account under their project","Share a filled-in room with a link and export a PDF report"],"field_sources":{"name":0,"author":0,"version":0,"commerce":0,"homepage":0,"keywords":0,"support_url":0,"capabilities":0,"release_notes":0,"review_case_counts":0,"commerce_description":0,"availability_countries":0},"release_notes":"First public version.
