  Introduction: In defense platforms such as submarines, ships, aircraft, and land vehicles, noise and vibration directly affect stealth, communication, and crew comfort. Excessive structural-borne or airborne noise can compromise operational effectiveness and even risk detection in naval operations. To prevent this, defense projects mandate SBN & ABN testing as per MIL-STD-740, MIL-STD-1474, ISO 10816, and ISO 3744 . This blog explains what SBN & ABN testing means, why it’s important, and how Indian defense suppliers can achieve compliance. 1️⃣ What is Structural-Borne Noise (SBN)? Noise generated by mechanical vibrations transmitted through the structure of equipment (e.g., pumps, motors, gear systems). Measured as vibration levels that propagate through structural paths. Critical in submarines and naval vessels , where vibration must be minimized for stealth. 2️⃣ What is Airborne Noise (ABN)? Noise radiated directly into the air from equipment. ...

  Introduction If you're a defense equipment manufacturer or system integrator in India, complying with MIL-STD-461 is not just a requirement — it’s your gateway to qualifying for Army, Navy, or Air Force tenders. This standard is essential for ensuring your equipment meets EMI/EMC (Electromagnetic Interference/Compatibility) requirements, as mandated by the Indian defense sector. In this guide, we’ll explain what MIL-STD-461 is, who needs it, and how to get certified step-by-step in India. What is MIL-STD-461? MIL-STD-461 is a United States Military Standard that outlines the EMI/EMC testing procedures for electrical and electronic equipment. It ensures that the device does not emit or is not susceptible to unwanted electromagnetic interference. The common versions include: MIL-STD-461E MIL-STD-461F MIL-STD-461G Who Needs MIL-STD-461 Certification in India? You must comply with MIL-STD-461 if you’re involved in: Supplying electro...
