Scope

GB/T 18698-2002 is the English-translated version of 声学信息技术设备和通信设备噪声发射值的标示.

GB/T 18698-2002 — This standard applies to information technology and telecommunications equipment. This standard specifies: noise emission labeling method for determining the value, manufacturer in the technical documentation shall provide acoustic and product information, manufacturer's noise emission values ??of the test methods indicated.

This standard uses the GB/T 18313 and GB/T 14574, GB/T 14573 provides a unified approach to get the noise data.

The basic noise emission values ??are labeled A-weighted sound power level of the declared value L (wAd) (corresponding to GB/T 14573 requirements L (c) the maximum statistical value) and the operator position or the position of the A-weighted persons present SPL declared value L (pAm) (average).

Using the A-weighted sound power level indicated value L (WAd) comparable noise emission of different products can be expected system device, or working position noise exposure level.

What this standard covers

This standard applies to information technology and telecommunications equipment. This standard specifies: noise emission labeling method for determining the value, manufacturer in the technical documentation shall provide acoustic and product information, manufacturer's noise emission values ??of the test methods indicated. This standard uses the GB/T 18313 and GB/T 14574, GB/T 14573 provides a unified approach to get the noise data. The basic noise emission values ??are labeled A-weighted sound power level of the declared value L (wAd) (corresponding to GB/T 14573 requirements L (c) the maximum statistical value) and the operator position or the position of the A-weighted persons present SPL declared value L (pAm) (average). Using the A-weighted sound power level indicated value L (WAd) comparable noise emission of different products can be expected system device, or working position noise exposure level. Calculate single or multiple sound sources of exposure level, although the amount is most useful single source of the A -weighted sound power level of the declared value L (WAd), but you can also use the A-weighted sound pressure level of the declared value L (pAm), estimating the closest vicinity of the device separating member exposure Level.
