| Abstract: | A type of ultra low power consumption monitoring system is developed for marine ambient noise.Noise signal acquired by hydrophone can automatically achieve gain amplification,digital filtering and A/D conversion.The raw data acquired have been stored by high capacity storage flash in real time.This system has been tested in the shield room and pool,working stably for several days.The data has been sampled successfully.The actual situation has been reflected almost by data playback results. |

| Keywords: | low-power marine ambient noise automatic gain amplification digital filter high capacity storage |
