Table 7

Comparison of ISO 10052 based survey method and proposed survey method bases on the KS and Korean building regulations.

	ISO 10052	Proposed
Source room	Near the centre of the source room. A single position is sufficient if the floor and slab are isotropic.	Centre point of the room Centre and one perimeter point at the window side Perimeter point: 0.75 m from the boundary walls or windows
Receiving room	Two fixed positions including that near the centre position, at different heights. Distances between the microphones and room boundaries is 0.5 m.	Centre point of the room. Centre and one perimeter point at the window side. Height: 1.2 m. Perimeter point: 0.75 m from the boundary walls or windows.
SNQ	A-weighted maximum impact sound pressure level (L_iA,Fmax) with octave bands (63–500 Hz). Overall A-weighted maximum impact sound pressure level (measured directly using the sound level meter).	A-weighted maximum impact sound pressure level (L_iA,Fmax) with octave bands (63–500 Hz).
