【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、水中音響特に海洋計測における音響雑音を収
集するための深深度雑音計測装置に関する。Description: TECHNICAL FIELD The present invention relates to a deep-depth noise measuring device for collecting acoustic noise in underwater acoustics, particularly in ocean measurement.
従来、この種の装置には海洋データの内でも流向，流
速，深度，電気伝導度等を磁気テープにアナログ型式で
収録するものがあり、比較的浅海で使用可能なものであ
つた。しかも、一担重錘により海底に着底させ、一定深
度に固定して海洋データを収録するものであつた。Conventionally, this type of device includes a device that records the flow direction, flow velocity, depth, electric conductivity, etc. in magnetic tape in an analog format even in ocean data, and was usable in relatively shallow water. Moreover, the ocean floor data was recorded by landing on the sea floor with a single weight and fixing it at a certain depth.
前記海洋データの内海洋雑音を収録する場合には、水中
マイクホンを船やブイから吊下して、水中マイクロホン
が収集した海洋データをマイクロホンから電導ケーブル
を介して収録する。When recording the ocean noise in the ocean data, the underwater microphone is suspended from a ship or a buoy, and the ocean data collected by the underwater microphone is recorded from the microphone via a conductive cable.

避難しなければならないほどの悪天候の場合、海中雑音
の収録が不可能となる問題がある。However, such a conventional example, when the weather and sea conditions deteriorate, the conductive cable connected to the underwater microphone is guided to a ship or a buoy, so that the underwater microphone spreads noise transmitted through the conductive cable, In addition, under bad weather conditions such as evacuation, it is impossible to record underwater noise.
また、従来例のような吊下式では、電導ケーブルを長く
すると水中マイクロホンが海潮流により大きく流される
ため、希望地点の雑音が収録できず、電導ケーブルの長
さが制限される。そのため、比較的浅い深度での海中雑
音しか収録できない問題がある。Further, in the suspension type as in the conventional example, when the conductive cable is lengthened, the underwater microphone is largely swept by the sea tide, so that noise at a desired point cannot be recorded and the length of the conductive cable is limited. Therefore, there is a problem that only underwater noise can be recorded at a relatively shallow depth.
