Sound Measurement--Self-Propelled Agricultural Equipment--Exterior

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J1008_200710
  • Current
Published 2007-10-16 by SAE International in United States
This SAE Recommended Practice sets forth the instrumentation and procedures to be used in measuring exterior sound levels of self-propelled agricultural field equipment of 15 kW (20 net engine hp) or greater. It is not intended to cover operation of safety devices (such as alarms), or equipment used primarily in stationary operation. The sound levels obtained by using this test procedure are repeatable and representative of the higher range of sound levels generated by the machine in normal road transport. The sound levels are not intended to represent the average or equivalent sound levels over a field use cycle.

Acoustics--Measurement of Airborne Noise Emitted By Earthmoving Machinery--Operator's Position--Stationary Testing Condition

  • Current
Published 2003-06-17 by SAE International in United States

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 in a stationary test condition.

Sound Power Level Measurements of Earthmoving Machinery-- Static and In-Place Dynamic Methods

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J1805_200301
  • Historical
Published 2003-01-30 by SAE International in United States
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…

Sound Measurement--Construction Site

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J1075_200006
  • Historical
Published 2000-06-28 by SAE International in United States
This SAE Standard sets forth measurement procedures and instrumentation to be used for determining a "representative" sound level during a representative time period at selected measurement locations on a construction site boundary. The document is not intended for use in determining occupational hearing damage risk. Determination of a representative time period is left to the judgment of the user.

Sound Measurement--Trenching Machines

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J1262_199907
  • Current
Published 1999-07-08 by SAE International in United States
This SAE Standard specifies procedures for measuring operator and exterior sound levels emitted by self-powered trenching machines regardless of engine size. This procedure does not cover operation of devices such as backup alarms, horns, or accessories such as paving breakers. The sound levels obtained using this procedure are repeatable and representative of the higher range of sound levels generated by machines under actual field operating conditions, but do not necessarily represent the average sound level over a field use cycle. Measurement and calculation of the operator's sound exposure should follow SAE J1166.

Sound Measurement--Off-Road Self-Propelled Work Machines Operator-Work Cycle

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J1166_199810
  • Historical
Published 1998-10-01 by SAE International in United States
This SAE Standard sets forth the procedures to be used in measuring sound levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116: Crawler Loader Wheel Loader Dumper Tractor Scraper Grader Crawler Tractor with Dozer Wheel Tractor with Dozer Pad Foot Wheel Compactor with Dozer Backhoe Hydraulic Excavator Log Skidder Excavator and Wheel Feller-Buncher Pipelayer Roller/Compactor Trencher Sweeper The instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle. A method to relate the time weighted average sound level at the operator station(s) to operator sound exposure is also provided.

Sound Measurement--Off-Road Work Machines--Operator--Singular Type

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J919_199504
  • Historical
Published 1995-04-01 by SAE International in United States
This SAE Standard describes the instrumentation and procedures to be used in measuring sound levels at the operator station for self-propelled sweepers as defined in SAE J2130 and self-propelled off-road work machines in categories 1, 2, 4, and 5, of SAE J1116. This SAE document is applicable to machines that have operator stations where the operator can either stand or sit and will be either transported by, or walk with the machine during its operation. The sound levels obtained using this procedure are repeatable and representative of the higher range of sound levels generated by machines under actual field operating conditions. Due to variability of field operating conditions, this data is not intended to be used for operator noise exposure evaluations. Measurement and calculation of the operator's sound exposure should follow SAE J1116.

Sound Measurement--Off-Road Work Machines--Exterior

Acoustics--Measurement of Airborne Noise Emitted By Earthmoving Machinery--Method for Determining Compliance With Limits for Exterior Noise--Stationary Test Condition

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J2102_199106
  • Current
Published 1991-06-01 by SAE International in United States
This SAE Standard describes a method for determining the exterior noise emitted by earthmoving machinery in terms of the A-weighted sound power level while the machine is in a stationary test condition. At six positions on a hemispherical surface, the equivalent continuous A-weighted sound pressure levels are measured. The A-weighted sound power level of the machinery is calculated from the measured values.

Acoustics--Measurement of Noise Emitted By Earthmoving Machinery At the OperatorS Position--Simulated Work Cycle Test Conditions

SLTC - Earth Moving Machinery Sound Level
  • Ground Vehicle Standard
  • J2105_199106
  • Current
Published 1991-06-01 by SAE International in United States
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…
