Foreword

This standard replaces GB/T 10491-1989 "lightweight gas turbine equipment noise values \u200b\u200band methods of measurement." This standard compared with GB/T 10491-1989, the main changes are as follows. --- The name of the standard was changed to "Aviation derivative gas turbine equipment and methods of measurement noise value"; --- Increasing the foreword; --- The chapter title "standard value" to "noise level limit value", and the noise level limit of the gas turbine from the outer insulation cover at 1m Provisions of the original 90dB (A) down to 85dB (A), reflecting the level of technological development of today's equipment manufacturing, and more concerned about the ring Environmental and social harmony, in addition to the content and scope of the noise level limits were necessary complement (Chapter 4 of this edition); --- Modify the background noise and atmospheric conditions and other requirements for the measurement environment (edition 5.2); --- Modify the background noise data correction and calculation of the average measured A sound level data (edition 6.1). Appendix A of this standard is an informative annex. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee turbine (SAC/TC259) centralized. This standard was drafted.

3 Terms and Definitions

Gas turbine terms and definitions GB/T 3947 and GB 3102.7 acoustics terms and definitions established and GB/T 10489 established appropriate For this standard.

4 noise level limit

4.1 standard with A-weighted sound level (hereinafter referred to as. A sound level) as an evaluation value. If desired, an optional measure sound pressure level (C sound level) and Octave band sound pressure level, but not as a basis for evaluation. 4.2 at full load and stable operation of the gas turbine, the average noise level at 1m away from the acoustic hood should not exceed 85dB (A). Gas turbine compartment Acoustic hood 1m at the noise level limit value should be based on Standard of noise at boundary of industrial enterprises in the region to install the unit performed, or urban area ring Environmental noise standards, taking into account the distance unit acoustic cover plant community, as well as on noise transmission Movies gas turbine plant or insulation of sound barrier Sound, calculated by the purchaser after the presentation and after consultation with the contractor OK. 4.3 should be based on the specific circumstances of the plant boundary noise or environmental requirements and on-site, after calculation, made by the purchaser and in consultation with the contractor for fuel Gas turbine noise level limit the following components at the outer 1m make provisions for. air intake, exhaust diffuser, acoustic cover vents and chimney outlet. 4.4 turbine control room noise level (local control room) should not exceed within the 70dB (A). 4.5 at full load and stable operation of the gas turbine, the average noise level of its outer insulation cover at 120m should not exceed 60dB (A). 4.6 turbine working under special conditions, the allowable noise level by the purchaser and the contractor as otherwise agreed. 4.7 Purchaser technical documents shall clearly indicate the scope of the noise level limit value. Unless otherwise specified, the scope of the noise level limit value It does not include transient noise sources and noise sources do not work jointly with the gas-turbine plant produced. If for multiple units running simultaneously, Units Number of units should be clearly stated; if combined cycle plant installed in the plant for inside and outside plant installation shall state apparatus that contains other
