Reliability Tests

High Temperature Test: Microphone subjected to +60℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Low Temperature Test: Microphone subjected to -25℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Humidity Test: Microphone exposed to 40℃ and 90-95% relative humidity for 96 hours, followed by 6 hours of normal temperature lay.

Temperature Cycle Test: Microphone subjected to rapid temperature changes from normal temperature to +60℃ ±3℃ for 1 hour (normal temperature lay for 3 hours) and then to -25℃ ±3℃ for 1 hour (normal temperature lay for 3 hours).

Sensitivity Stability: Sensitivity remains within ±3dB of the initial sensitivity after each environmental test.
