SAE AIR1407A-2012 近场和远场螺旋桨噪声预测规程

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This high static thrust and relatively low installed engine power for propellers has been a factor in their consideration as propuslors for vertical and short take-off and landing (V/STOL) aircraft. The simplicity and low cost of the propeller has historically been a factor in its selection for the majority of general aviation aircraft. With the increased emphasis on noise generated by all types of aircraft there has been an increasing interest in controlling the noise of new V/STOL and conventional transport aircraft as well as general aviation aircraft. To assist the designer of new aircraft as well as others interested in the noise characteristics of various propeller configurations the procedure described in this Aerospace Information Report (AIR) has been developed.

Prediction Procedure for Near-Field and Far-Field Propeller Noise

SAE AIR1751A-2012 起飞和降落器件飞机噪音横向衰减的预测方法

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. The SAE A-21 Committee on Aircraft Noise undertook in 1979 the development of a uniform and consistent method for the prediction of lateral attenuation. The project was divided into two phases: (1) A short-term phase in which correlations of flight data were made using frequency-weighted and time-integrated measures of the noise, such as Effective Perceived Noise Level (EPNL) and Sound Exposure Level (SEL), see Appendix A; and (2) A long-term phase in which the effects of various sound-propagation phenomena would include ground reflection effects, refraction effects, and airplane shielding effects, as well as other ground and engine/airplane installation effects. This Aerospace Information Report is directed to the short-term phase in order to produce an interim prediction method as soon as possible.

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. Data presented in this AIR are in terms of differences between one-third-octave-band free-field sound pressure levels and are intended for use in estimating far-field aircraft noise. Allowance may be made for the acoustic impedance of the ground surface and sound pressure levels at any height above the ground plane may be estimated. In estimating the long-term time averaged sound level at several locations around an airport served by a mix of airplane types under a variety of atmospheric conditions, airplane operational weights, and flight procedures, it would be more appropriate to use the method of prediction for lateral attenuation given in reference 1.

Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. The interior noise within the relatively small space of civilian or military rotorcraft results from exterior and interior noise sources. Interior noise measurements may be required in order to develop or evaluate acoustical treatment designs that will provide a necessary degree of crew and passenger comfort. This document describes recommended methods and procedures for uniform measurement, analysis and reporting of sound pressure levels in the interior of rotorcraft. Satisfactory measurements of noise in personnel-occupied rotorcraft cabins may require test techniques different from those prescribed for other types of aircraft (ARP1323) because rotorcraft operate under significantly different flight conditions. Recommendations of this ArP apply to the recording of acoustical data on magnetic tape and the subsequent processing and analysis of the recorded data.

SAE AIR1845A-2012 飞机附近噪声计算规程

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This Aerospace Information Report (AIR) describes procedures for calculating sound exposure levels at ground locations resulting from operations of jet and propeller driven airplanes in the vicinity of an airport. The procedures assume that reference noise and performance data are available for each airplane involved. The fundamental element of the procedures is a method for calculating the A-weighted sound exposure level (SEL) that would be produced, on average, by any specific airplane when performing any specified operation. Procedures are given for calculating sound exposure levels for individual airplane operations and for the average sound level produced by the cumulative effect of a series of different airplane operations, normally expressed in terms of day-night average sound level (DNL) averaged over an appropriate long time period. The principal purpose of using the procedures recommended in this AIR to calculate contours of equal average sound levels is to assist in land-use planning around airports. Contours of equal sound level may be constructed by connecting lines through individual points of constant sound level. While the procedures of this AIR describes the computation of sound levels at any point in the vicinity of an airport, the procedure for calculation of contours is computer-program dependent and is not a part of this AIR.

Procedure for the Calculation of Airplane Noise in the Vicinity of Airports

SAE ARP1323B-2012 巡航器件航空器内部声音压力等级的类型测量

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. The primary measurement procedure recommended in this ARP includes the recording of sound pressure signals in the interior of an airplane during steady state cruise conditions with analysis after the flight into octave band (or one-third octave band) sound pressure levels. Alternatively, spectral analyses of the sound pressure signals may be performed directly on board an airplane. Though less flexible than the primary measurement procedure, the alternative procedure offers the advantage of immediate availability of frequency band or frequency weighted sound pressure levels that are consistent with those measured in accordance with the procedures in ISO 5129. In view of the range of possible measurement this ARP provides electroacoustical performance requirements for a complete system from a microphone to the readout device. Various individual components of a measurement system may be selected so long as the total measurement system complies with the requirements. Recommendations of this ARP are not intended to satisfy the stringent requirements for airplane design or development. Also, they may not be directly applicable to measurements of sound pressure levels in the interior of helicopters or general aviation airplanes where special constraints on measurement locations and test procedures may exist. Specific recommendations for measurement of interior sound pressure levels in helicopters are given.

SAE AIR1327A-2012 反射平面产生的音响效果

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. The purposes of this AIR are to provide technical background associated with the problem of correcting measured noise spectra to the "free field" wherein the measurements are taken in the proximity of a ground plane; to provide practical examples of correction methods; and to present some techniques for minimizing the errors associated with the measurement of noise in the presence of ground planes. The application of this AIR should assist the acoustician in understanding the spectral effects of the reflection phenomena and suggests some methods for obtaining more accurate "free field" acoustic data; however, the AIR does not purport to provide unique, exact solutions to all measurement problems, for each measurement situation is unique in itself. Of paramount importance to the correction procedures is a good knowledge of the acoustic impedance of the ground plane and the geometry associated with the measurement setup. A method of measuring these ground plane characteristics is described.

This part of ISO 18437 establishes the principles underlying ISO 18437-2 to ISO 18437-5 for the determination of the dynamic mechanical properties (i.e. elastic modulus, shear modulus, bulk modulus, loss factor, and Poisson ratio) of isotropic visco-elastic resilient materials used in vibration isolators from laboratory measurements. It also provides assistance in the selection of the appropriate part of this International Standard. This part of ISO 18437 is applicable to isotropic resilient materials that are used in vibration isolators in order to reduce: a) the transmissions of audio frequency vibrations to a structure that can, for example, radiate fluid-borne sound (airborne, structure-borne or other); b) the transmission of low frequency vibrations which can, for example, act upon humans or cause damage to structures or sensitive equipment when the vibration is too severe; c) the transmission of shock and noise. The data obtained with the measurement methods that are outlined in this part of ISO 18437 and further specified in ISO 18437-2 to ISO 18437-5 can be used for: 1) the design of efficient vibration isolators; 2) the selection of an optimum resilient material for a given design; 3) the theoretical computation of the transfer of vibrations through vibration isolators; 4) information during product development; 5) product information provided by manufacturers and suppliers; 6) quality control.
