High reverberation — dialogue is likely to sound "echoey." Temporary acoustic treatment (panels, blankets, heavy curtains) is recommended before recording.

Simplified estimate using the Sabine formula (RT60 = 0.161 × V / A) at 500 Hz, without accounting for irregular geometry, diffusion or modal resonances. Useful as a quick guide before deciding whether a room needs acoustic treatment for dialogue recording.
