This document is a method standard for on-site measurement of impact sound insulation of buildings. The impact source used to excite partitions radiates impact noise during measurement, including
Including impactors and rubber balls, but these two impact sources do not fully represent all possible actual impact types on building floors or stairs.
Impactors are used to evaluate a variety of light and hard impacts, such as those from the footsteps of a person walking in hard heeled shoes or from falling objects. Depend on
The evaluation method in GB/T 50121 or ISO 717-1 calculates the single-value evaluation quantity, which will use the impact sound measured by the impactor
Sound insulation is linked to subjective assessments of impacts that typically occur on residential building floors or stairs. Using the impactor as the impact source is also used to press

The impactor is measured as the impact source.
Rubber balls are used to evaluate heavy and soft impacts, such as those from barefoot walkers or children jumping, to "fast-stop" maximum sound pressure
level to quantify the absolute magnitude associated with human disturbance.

3 Terms and Definitions
The following terms and definitions apply to this document.
Note. The ISO and IEC standard terminology database URLs are as follows.
3.1
Li
Taking the impactor as the impact source, the ratio of the average value of space and time of the square of the indoor sound pressure to the square of the reference sound pressure is the logarithm to the base of 10
Multiplied by 10, the spatial average refers to the average of the central area of the room where the effect of near-field radiation at the boundary of the room is negligible.
Note. Li is expressed in decibels (dB).
