The invention discloses an acoustic device, and belongs to the technical field of noise measurement. The acoustic device comprises a box body, the box body comprises a first shell and a penetrating pipe arranged on the first shell in a protruding mode, and the first shell and the penetrating pipe are communicated to form a containing cavity; the buffering mechanism is attached to the periphery of the penetrating pipe; the measuring mechanism comprises a first end and a second end which are oppositely arranged, the first end is arranged in the containing cavity, and the second end penetrates through the penetrating pipe and is arranged outside the box body; the sound transmission plate is arranged at the end, away from the containing cavity, of the first shell so as to seal the containing cavity. The acoustic device receives underwater radiation noise generated by the ship and external equipment through the sound transmission plate, the accuracy and reliability of underwater radiation noise measurement are effectively improved, conditions are provided for long-term monitoring of the underwater radiation noise, the test difficulty is effectively reduced, a large amount of auxiliary work of far-field underwater acoustic measurement is avoided, and the measurement efficiency is improved. And the problem of interference of mechanical vibration of the ship on the measuring mechanism of the acoustic device is solved through the buffer mechanism.
本申请公开了一种声学装置,属于噪声测量技术领域。声学装置包括:箱体,箱体包括第一壳体和凸设于第一壳体的贯穿管,第一壳体与贯穿管连通形成容置腔;缓冲机构,缓冲机构贴合于贯穿管的外周;测量机构,测量机构包括相对设置的第一端和第二端,第一端设置于所述容置腔,第二端穿过贯穿管且第二端设置于箱体外;透声板,透声板设置于第一壳体远离容置腔的一端以封闭容置腔。该声学装置通过透声板接收船舶自身和外界设备产生的水下辐射噪声,有效提高水下辐射噪声测量的精准度和可靠性,为水下辐射噪声的长期监测提供条件,有效降低测试难度,避免远场水声测量的大量辅助工作,通过缓冲机构解决船舶机械振动对声学装置的测量机构的干扰问题。
