Kalkulaator hindab ruumi akustilisi parameetreid: järelkaja aeg T₂₀, kõneosavus C₅₀ ja helitugevus G. Need parameetrid on defineeritud standardis ISO 3382 osad 1 ja 2.

Arvutused tehakse nii hajutatud kui ka mittehajutatud helivälja tingimustes. Järelkaja aeg Sabine’i valemi järgi, mis eeldab hajutatud helivälja, arvutatakse kõikide juhtumite jaoks. Sabine’i arvutus toimub vastavalt protseduurile, mis on kirjeldatud standardis EN 12354-6.

Mittehajutatud tingimused esinevad tavaliselt ruumides, kus ripplae all paiknev neelav lagi domineerib ruumi helisummutust. Kalkulaator kontrollib mittehajutatud tingimusi ja kui nõuded on täidetud, arvutatakse ruumi akustilised parameetrid T₂₀, C₅₀ ja G.

Ecophon annab sobivate parameetrite väärtustele soovitusi kõigi ruumitüüpide jaoks. Soovitused põhinevad meie tänasel kogemusel.

Furnishing

Sparse Hõredat ruumi iseloomustab väike hulk mööblit või varustust ning paljad, heli peegeldavad seinad. Näiteks võib selleks olla klassiruum, konverentsiruum või kontor, kus on peamiselt laudu ja riidest polsterdamata toolid põrandapinnal ning seintel on väga vähe kappe või riiuleid. Sellisel juhul vastab mööbli maht ligikaudu 1% ruumi kogumahust.

Normal Tavapäraselt sisustatud ruum tähendab ruumi, kus mööbel on paigutatud nii põrandapinnale kui ka seinte äärde. Näiteks võib selleks olla klassiruum, kontor või konverentsiruum, kus põrandapinnal on lauad ja toolid ning seinte ääres riiulid ja kapid.

Dense Tihedalt sisustatud ruum on ruum, kus on suur hulk mööblit ja varustust ning osa mööblist on polsterdatud, näiteks kontoritoolid ja diivanid. Näiteks võib haigla hooldusruumi vooditega pidada tihedalt sisustatud ruumiks.

Ruumide akustilise mugavuse (Room Acoustic Comfort, RAC) arvutused, mis on mõeldud ruumidele, kus on helisummutavad laed. See arvutus annab mõõtmistega parema vastavuse kui Sabine’i valem.
