abstract = "This study investigates the structural properties of a 55-mm thick tatami mat floor, a flooring prevalent in Japan. Building on previous research that introduced a tatami mat floor designed for vibration isolation, this work extends the investigation to heavy-weight floor impact sound
mitigation on tatami mats measuring 900 \texttimes 1800 mm. The current study expands the tatami mat size to 2700 \texttimes 2700 mm and evaluates the sound insulation performance of vibration-isolated tatami mats placed on a concrete slab and dry floating floors. The experimental findings are summarized
as follows: (1) The deployment of vibration-proofed tatami mats atop dry floating floors yielded notable improvements under tire-induced vibrations, achieving reductions of 4-6 dB in the 63-Hz band, 3-7 dB in the 125 Hz band, 4-6 dB in the 250 Hz band, and 6-9 dB in the 500 Hz band. (2) Similarly,
with rubber ball-induced vibrations, installing vibration-proofed tatami mats on dry floating floors resulted in sound level reductions of 2-3 dB in the 63 Hz band, 4-5 dB in the 125 Hz band, 8 dB in the 250 Hz band, and 8-11 dB in the 500 Hz band.",
