Book excerpt: This SAE Recommended Practice sets forth the instrumentation and procedures to be used in measuring sound levels at the operator station for powered mobile construction machinery of 15 kW (20 bhp) rated and over. This Recommended Practice is to cover machinery that has operator stations where the operator can either stand or sit and will be transported by the machine during its operation. The sound levels obtained by using the test procedures set forth in this SAE Recommended Practice are in general repeatable and are representative of the higher range of the sound levels generated by the machinery under field operating conditions, but do not necessarily represent the equivalent sound level over a field use cycle.

This book was released on 1991 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is carrying out a simulated work cycle. This SAE standard is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. A simulated rather than an actual work cycle test condition is chosen. Simulated work cycles provide acceptable noise emission data which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem. Specific procedures are described in this document to enable the sound pressure level at the operator's position,with the machine in a simulated work cycle test condition, to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version are to be fitted since this is the configuration most likely to exist when the machine is in actual use. This document enables compliance with noise limits to be determined. It can also be used for evaluation purposes in noise reduction investigations. An additional special test code is given in SAE J2104/ISO 6395. This other special test code is intended to be used to determine the noise emitted by earthmovign machinery in terms fo the A-weighted sound power level while the machine is in a simulated work cycle test condition. Corresponding measurements of exterior noise and noise at the operator's position under stationary test conditions are described in SAE J2102/ISO 6393 and ISO J2103/ISO 6394, respectively.

It is not intended to cover operation of safety devices such as backup alarms or accessories such as paving breakers. The sound levels obtained by using the test procedures set forth in this SAE Recommended Practice are repeatable and are representative of the higher range of sound levels generated by the machinery under actual field operating conditions, but do not necessarily represent the average sound level over a field use cycle. For measurement and calculation of the operator's sound exposure, the procedure should follow the SAE Recommended Practice J1166a.

Book excerpt: This SAE Standard describes a method for determining the noise emitted to the environment by earthmoving machinery in terms of the A-weighted sound power level while the machine is working under dynamic test conditions. This SAE Standard is special test code for specific types of earthmoving machinery. It is an extension of SAE J2101/ISO 4872, which contains the general requirements for construction equipment. A simulated dynamic rath than an actual work cycle test condition is chosen. Dynamic test conditions provide acceptable noise emission data, which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem Specific procedures are described in this document to enable the sound power emission in dynamic test conditions to be determined in a manner that is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version are to be fitted since this is the configuration most likely to exist when the machine is in actual use. This document enables compliance with noise limits to be determined. It can also be used for evaluation purposes in noise reduction investigation. An additional special test code is given in SAE J2105/ISO 6396.2. This other special test code is intended to be used to determine the noise emitted by earthmoving machiner, with the machine in dynamic test conditions, measured at the operator's position in terms of the equivalent continuous A-weighted sound pressure level. Corresponding measurements of noise emitted to the environment and noise at the operator's position under stationary test conditions are described in SAE J2102/ISO 6393 and SAE J2103/ISO 6394, respectively.

Download or read book Sound Power Level Measurements of Earthmoving Machinery Static and In Place Dynamic Methods written by SLTC - Earth Moving Machinery Sound Level and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Standard is used to determine the exterior A-weighted equivalent sound power level of static and in-place dynamic machines (dozer, loader, excavator, and backhoe) similar to the sound power obtained in ISO 6393 static and ISO 6395 dynamic sound power test procedures. Additional machine types, specifically sweepers and scrubbers, covered by SAE J2130 have been added, and other work machine types covered by SAE J1116 may be added with appropriate cycle descriptions and machine preparation. The recommended test procedures include conventional integrating sound pressure level methods or the sound intensity method using paired microphones. The sound intensity methodology provides a practical indoor alternative and permits measurement in the factory environment. The procedures in this document assume that the dominant sources are not highly sensitive to load (i.e., cooling fan, engine, track system). This test can be used as a substitute for the ISO 6393 static and ISO 6395 dynamic sound power tests for many machine types. The requirements for the machine setup and operation, and the microphone array and hemispherical measurement surface are given in this document. This document shall be used in conjunction with instrumentation manufacturer's recommendations and SAE J/ISO 9614-1. The accompanying sound intensity procedure clarification is provided pending more widespread understanding of sound intensity.
