Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity (and consequently momentum) occurs from the impact during a collision by a controlled deformation; in recent years, it is also incorporated into trains and railcars. WitrynaAnalog microphones have a wide range of sensitivities. Some dynamic microphones might have sensitivity as low as –70 dBV. Some condenser microphone modules have integrated preamps so they have extra high sensitivity of –18 dBV. Most analog electret and MEMS microphones have sensitivity between –46 dBV and –35 dBV (5.0 mV/Pa …
