Vibration Isolation of Existing Buildings in Microvibration Traffic Environment

Table 2

Isolation difference between different floors of typical rooms.

Isolation difference of each floor	Midspan	Wall-floor junction	Evaluation of isolation effects
Indoor room	0.1 dB∼0.6 dB	0.06 dB∼0.22 dB	The isolation level of each floor at the midspan differs greatly, and the difference is small at the junction
Kitchen (precast slab)	0.1 dB∼0.9 dB	0.03 dB∼0.17 dB	The isolation level of each floor at the midspan differs greatly, and the difference is small at the junction
Bathroom (cast-in-place slab)	0.24 dB∼0.78 dB	0.08 dB∼0.55 dB	The isolation level of each floor at the midspan differs greatly, and the difference is relatively large at the junction
