Aircraft ground support equipment - General requirements - Part 4: Noise measurement methods and reduction

This document deals with noise reduction as a safety requirement. It also specifies the methods for determining the sound pressure level at workstations, other specified positions and the sound power level of GSE during intended use.
The test results are not applicable to the determination of daily exposure to noise for the operator.
This part of EN 1915 is intended to be used in conjunction with the other parts of EN 1915, and with the relevant part of EN 12312.

Overview

EN 1915-4:2004+A1:2009 (CEN) specifies noise measurement methods and noise‑reduction requirements for aircraft ground support equipment (GSE). It sets out how to determine A‑weighted sound pressure levels at operator workstations and other specified exterior positions, and when to determine the sound power level of GSE during intended use. The standard treats noise as a safety requirement and is intended to be used alongside other parts of EN 1915 and the relevant parts of EN 12312. Note: the test results from this standard are not applicable for determining an operator’s daily noise exposure.

Key topics and technical requirements

• Measurement targets
  • Sound pressure levels at operator’s position(s), workstations and other specified exterior positions.
  • Sound power level when A‑weighted emission exceeds specified thresholds.
• Thresholds and conditions
  • If A‑weighted emission sound pressure level > 80 dB, a sound power determination is required.
  • Idle conditions must be measured when idle A‑weighted levels exceed 70 dB.
• Test procedures and environment
  • Tests on level, hard reflective surfaces with prescribed test environment per referenced acoustics standards.
  • Measurements during standstill and driving (for self‑propelled GSE); simulated driving allowed if validated.
  • For cabins, doors/windows closed; air‑conditioning/ventilation set to specified speeds/positions to avoid measurement bias.
• Equipment and configuration
  • GSE shall be representative of typical supply condition, with operator present.
  • Multiple operator positions must be measured where applicable.
• Noise reduction guidance
  • Identifies typical noise sources (propulsion/auxiliary engines, fans, exhausts, hydraulic pumps, rolling noise, mechanical impacts).
  • Encourages design and layout measures: vibration damping, silencers, ducting, component selection, casing, and operational/organizational controls.
• Reporting and verification
  • Specifies test reporting content, declaration of noise emissions and verification procedures.

Practical applications

• Use this standard to:
  • Define noise‑test protocols for manufacturers and acoustic test labs.
  • Guide GSE design decisions to reduce operator and community noise.
  • Prepare noise declarations and technical documentation for procurement and conformity assessment.
  • Inform airport noise management, equipment selection, and operational procedures to reduce workplace noise hazards.

Who uses this standard

• GSE manufacturers and design engineers
• Acoustic test laboratories and certifying bodies
• Airport operators, fleet managers and procurement teams
• Safety and compliance officers working with machinery directives and EU essential requirements

Related standards

• EN 1915 series (Parts 1–3, general safety, vibration)
• EN 12312 (specific GSE requirements)
• EN ISO 3744, EN ISO 11201, EN ISO 4871, EN ISO 12100 (referenced acoustics and machinery safety standards)
