This SAE Standard is applicable to machinery of 15 kw (20 bhp) rated and over, that have operator stations where the operator can either stand or sit and will be transported by the machine during its operation. It is not intended for use with agricultural equipment. The sound levels obtained by using the test procedures set forth in this SAE Standard 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. For measurement and calculation of the operator’s sound exposure, use SAE Recommended Practice J1166a.

This SAE Recommended Practice sets forth the procedures to be used only in measuring sound levels and the determination of the time weighted sound level at the operator station(s) of earthmoving machinery of 15 kW (20 bhp) and over. Earthmoving machinery is defined per SAE J1057a. This recommended practice is applicable to earthmoving machinery which has operator station(s) where the operator can either stand or sit and is transported by the machinery during operation. The recommended practice describes the instrumentation requirements and specifies work cycles for earthmoving machinery. The recommended practice describes the method used to calculate the time weighted average sound level at the operator station(s) identified in the practice as Leq(5) for continuous operation of the work cycle. A method to relate the time weighted average sound level at the operator station(s) to operator sound exposure is also provided.

This SAE Recommended Practice sets forth 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. It concerns the community adjacent to the construction site, and it is not intended for use in determining occupational hearing damage risk.

This SAE Recommended Practice sets forth the procedures to be used only in measuring sound levels and the determination of the time weighted average sound level at the operator station(s) of powered mobile earthmoving machinery of 15 kW (20 bhp) and over. This Recommended Practice is applicable to earthmoving machinery which has operator station(s) where the operator can either stand or sit and is transported by the machinery during its operation. The Recommended Practice describes the instrumentation requirements and specifies work cycles for earthmoving machinery. The Recommended Practice describes the method used to calculate the time weighted average sound level at the operator station(s)—identified in this practice as Leq(5)—for continuous operation on the work cycle. A method to relate the time weighted average sound level at the operator station(s) to operator sound exposure is also provided.

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 SAE Standard sets forth the instrumentation and procedure to be used in measuring the exterior sound levels 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 document does not address the operation of safety devices such as backup alarms, horns, or accessories. The sound levels obtained by using the test procedures set forth in this document are repeatable and are 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 construction site boundary noise evaluations.

This SAE Recommended Practice establishes the following criteria for electrically operated forward warning horns on mobile construction machinery: (a) Forward warning horn performance requirements (b) Measurement technique for horn performance requirements (c) Laboratory environmental tests (d) Horn activation on the vehicle

This SAE Recommended Practice sets forth the instrumentation and procedure to be used in measuring exterior sound levels for powered mobile construction equipment of 20 rated bhp and over. It is not intended to cover operation of safety devices (such as backup alarms) and equipment designed primarily for operation on highways or within factories and building areas, aircraft, or recreational vehicles, such as snowmobiles and boats. The sound levels obtained by using the test procedures set forth in this SAE Recommended Practice are repeatable and representative of the sound levels generated by the equipment during normal operating conditions.

The job requirements, along with local, state, or national codes, should dictate whether a backup alarm device shall be used on construction and mobile outdoor industrial machinery. In the cases of those machines which do not distinguish in direction of working travel and where the machine is equipped so the operator can face the direction of travel each time (for example, certain compactors, loaders, and dozers), the use of a backup alarm device may not be applicable.
