PRIVACY & LIMITATIONS
Room and material ledgers stay local. No sound is captured.
Room dimensions, target RT60, material areas, and six-band absorption coefficients are calculated only in the current browser. ReverbPlan requests no microphone, records no sound, reads or plays no audio, and connects to no measurement platform, DSP, building model, or material database.
Diffuse-field statistics, not acoustic prediction
The tool sums area × absorption coefficient in six octave bands and calculates Sabine and Norris–Eyring estimates. It does not model room shape, material placement, incidence, scattering, coupled volumes, air loss, climate, occupancy changes, stage equipment, low-frequency modes, early reflections, clarity, isolation, noise, or SPL distribution; coefficients must come from reliable laboratory data matching the actual assembly and bands.
Avoid double-counting and measure after completion
CSV and reports contain room summaries and band results; optional checkpoints stay in the current browser. Equivalent areas for boundaries, furniture, people, and added treatment can overlap, so maintain an auditable material ledger; an acoustics professional should verify the design against drawings, manufacturer tests, and intended use, then measure after completion under applicable standards.
Advertising and local preferences
This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.
← Back to toolLocal report studio
The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.
Optional local checkpoints
Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
Analytics and your choices
Google Analytics measures page visits and tool openings. Visitors in the EEA, UK, Switzerland, mainland China, Canada, South Korea, and Türkiye are asked first; other identified regions start automatically. A previous refusal, GPC, or Do Not Track takes precedence. Tools work with either choice.
We use same-site Cloudflare connection information to determine the country or region, not your language, and do not save the IP address in the lookup. If the lookup fails, the Google tag still starts with regional consent defaults: analytics cookies in consent-required regions await permission, while Google may receive basic cookieless signals. Automatic startup is not recorded as your explicit consent.
Files, filenames, tool inputs, search terms, URL parameters, fragments, and results are excluded. Page names use fixed paths and referrers contain only the source site. Google processes visit identifiers and technical browser information. Enhanced measurement, Google signals, and ad-personalization measurement are disabled.
Turn analytics on or off through Privacy & analytics in the footer. Explicit choices are shared across enabled pages in a .miluland.com cookie for up to 180 days; automatic startup does not save an accepted choice. Turning it off stops this integration and clears accessible GA cookies. Advertising uses separate consent settings.
