SAE J1679 Noise, Vibration and Harshness (NVH) Testing for Military Vehicles
The SAE J1679 standard is a critical tool in the development of military vehicles. It provides guidelines for testing noise, vibration, and harshness levels to ensure that the vehicle meets specific performance criteria under various operating conditions. This service ensures that military vehicles are not only functional but also user-friendly, safe, and reliable.
SAE J1679 focuses on three key areas: sound pressure level (SPL), vibration acceleration, and harshness perception. The standard is designed to identify potential issues in the design phase of a vehicle's development cycle, thereby reducing costs and improving overall performance during production. This testing process helps manufacturers ensure that their products meet the stringent requirements set by military specifications.
The test procedure involves several stages, each aimed at assessing different aspects of NVH performance:
- Sound Pressure Level (SPL) Testing: SPL is measured in decibels (dB) and evaluates how much noise a vehicle produces. This measurement helps identify areas where sound insulation improvements are needed.
- Vibration Acceleration Testing: This assesses the mechanical vibrations experienced by occupants within the vehicle. Excessive vibration can lead to discomfort, reduced performance, and even structural damage over time.
- Harshness Perception Testing: This evaluates how smooth or jarring a ride is perceived by the operator or passenger. High harshness ratings could indicate unacceptably rough handling on part of the vehicle's suspension system.
During the testing process, the specimens are subjected to various environmental conditions that simulate real-world scenarios such as off-road driving or urban combat zones. This ensures that any issues identified during testing can be addressed before deployment in actual operational environments.
The acceptance criteria for SAE J1679 tests are stringent and tailored specifically towards military applications. Compliance with these standards is crucial not only for maintaining high quality but also to meet regulatory requirements imposed by various governing bodies worldwide.

Environmental and Sustainability Contributions
The SAE J1679 NVH testing also has significant environmental benefits. By optimizing the design of military vehicles to reduce noise pollution and improve fuel efficiency, these tests contribute positively towards achieving sustainability goals.
Noise reduction not only enhances operator comfort but also minimizes disruption to nearby communities. Lower noise levels contribute significantly to improving air quality by reducing exhaust emissions. Additionally, more efficient use of resources translates into reduced carbon footprints, aligning with global efforts aimed at combating climate change.
Moreover, sustainable practices in manufacturing and operation lead to long-term savings for both the government and taxpayers involved in funding such projects. These cost savings can be redirected towards other essential areas within defense budgets, promoting overall fiscal responsibility.
