Passive acoustic tornado detector and detection method |
摘要 |
A tornado detector includes a microphone which monitors outdoor noise for increasing amplitude within a frequency range characteristic of a tornado. When the sound pressure level within the passband of the detector exceeds established thresholds, logic is applied to determine whether the level is increasing at a rate indicative of an approaching tornado and therefore whether an alarm is to be sounded.
