        "shortDescription": "Room acoustics and absorbers",
        "longDescription": "Acoustic Index brings room acoustics into ChatGPT: a reverberation time calculator, the target values of the standards and a catalog of acoustic products with lab-measured sound absorption.\n\nDescribe a room and the app calculates it like the Acoustic Index calculator does: reverberation time per octave band from 125 to 4000 Hz, the target of the standard for the room's use (DIN 18041, ASR A3.7, BB93, ANSI S12.60 and others from 15 countries) and the absorption still missing. 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.",
