脉冲噪声
受到爆炸或枪炮等冲击性噪声可能是突发性噪声，也可能是在受控条件下发生的，即使仅仅在一次或几次无保护的接触后，也可能导致永久性听力损伤。因此，您的产品必须符合军事标准，并且在选择用于极端脉冲噪声测量的麦克风时要小心。
凭借GRAS系列麦克风，您可以保证拥有适合任何极端情况的设备，以及介于两者之间的所有设备。

FAQ for Impulsive Noise Measurement
What is impulsive noise in aerospace?
Impulsive noise is a short-duration, high-intensity acoustic event characterized by rapid rises and quick decays in sound pressure, unlike continuous noise. It includes blasts, impacts, and explosions that occur in aerospace environments.
Why does impulsive noise matter in aerospace testing?
Impulsive noise matters because it can cause structural stress, affect aircraft systems, and pose hearing risks, requiring precise measurement and control to ensure safety and compliance.
What are common sources of impulsive noise in aerospace?
Common aerospace sources include rocket launches, engine test explosions, blast events, blade vortex interactions on rotorcraft, and shock waves from high-speed flight.
How is impulsive noise measured accurately?
Accurate impulsive noise measurement uses high-dynamic-range microphones and fast sampling systems to capture brief, intense pressure spikes that standard sound meters cannot reliably record.
