Forte and Ortoleva report that Tomba del Gallo's visual and acoustic properties correspond with alpha-band dominance at 8 to 12 Hz, a band linked to relaxed alertness, sustained visual attention and suppression of irrelevant stimuli [15]. That claim moves from measured sound to brain rhythm, and the pipeline behind it is a computer vision saliency model, an architectural model, a handclap survey and simulated agents tracing plausible routes [4][8][19]. The same move appears in their treatment of frequency, where sounds below 1000 Hz are read as bodily rather than merely audible: capable of inducing vibration and disorientation, with potential effects on cognitive states [7]. That is a statement about human physiology fastened to a measurement of a room.
The burial chamber is 3.31 metres by 2.50 metres [10], which is 8.3 square metres of floor [18]. That figure carries more of the calm reading than the paintings do. The authors note the room is easy to light with candles because it is small [12], and they report short reverberation times, with sound propagating up and out of the tomb rather than accumulating [14]. What would settle the acoustic question is a comparison space of similar volume that wasn't designed for clarity, and no such space appears in the account. As written, the chamber both fails to accumulate sound and reverses that tendency on crossing the threshold from the corridor [14], a pairing that needs the full paper to reconcile.
The design inference rests on a contrast between two rooms [20]. Tomba del Gallo reads as orderly and visually led, with saliency clustering at the paintings and at the high-curvature zones where walls meet [13]; the Tomba dei Demoni Azzurri is offered as the disorienting counterpart [17]. The conclusion that these tombs were built to work on the living and not only to hold the dead [16] depends on the pair diverging, and a contrast between two rooms is not yet a pattern.
What earns confidence is the protocol. Recorded handclaps at fixed positions, with decay and travel measured through each tomb [6], is a procedure another team can repeat in the same chambers and either reproduce or fail to reproduce. That option does not exist for a reading of painted images, which is how the Tarquinia tombs, celebrated for their scenes of music, feasting and procession [2], have mostly been approached [3]. The saliency maps and the alpha-band correspondence sit further out from the evidence: modelled where the acoustics were measured.
