- Worth noticing
- The page explicitly distinguishes room echo treatment from soundproofing and warns that ordinary microphones struggle with low frequencies.
Field notes
The free estimate is described as using room size, absorber type, and panel quantity, with its calculation basis and absorption-coefficient sources provided. The fuller browser-based assessment remains in preparation: the page says it would examine frequency-dependent decay, reflections, and flutter echo, then suggest placements and budget-based quantities. It also cautions that ordinary microphones are less reliable at low frequencies.
