선박의 음향 차폐 판넬 장치{A sound isolation panel device for ships}A sound isolation panel device for ships

본 고안은 선박의 음향 차폐 판넬 장치에 관한 것이다. 더욱 상세하게는 음향차폐 판넬을 이용하여 선박의 격실 내에 발생되는 공기 소음을 흡음 및 차음함으로써 선박 격실 내의 소음 수준을 낮추는 음향 차폐 판넬 장치에 관한 것이다.The present invention relates to an acoustic shield panel device of a ship. More particularly, the present invention relates to an acoustic shielding panel device that lowers the noise level in a ship compartment by absorbing and shielding air noise generated in a compartment of a ship using an acoustic shielding panel.

일상 주변에는 각종 기계 설비의 가동, 자동차, 철도, 지하철, 항공기 등 교통 수단의 운행, 중장비를 이용한 각종 공사 또는 각종 음향 기기의 작동 등 여러 가지 요인에 의해 바람직하지 않은 소리, 즉 소음이 발생되기 마련이다.In everyday life, undesired sounds, ie noises, are generated by various factors such as the operation of various mechanical equipment, the operation of transportation means such as automobiles, railways, subways, aircrafts, the construction of heavy equipment, or the operation of various acoustic devices. to be.

이러한 소음은 개인적으로는 난청, 두통, 불안감 등을 유발하여 건강을 해치는 요인으로 작용하며, 산업 현장에서는 열악한 작업환경을 조성하고 진동을 발생시켜 생산성의 저하와 제품의 품질저하를 야기시키게 된다.These noises personally cause hearing loss, headaches, anxiety, etc., and cause harm to health, and in an industrial field, they create a poor working environment and generate vibrations, causing a decrease in productivity and product quality.

따라서, 소음 유발원들은 가능한 한 적은 소음이 발생되도록 설계되어야 하고, 불가피하게 발생된 소음이라면 가능한 한 소음이 외부로 전파되는 것을 차단하는 조치가 필요하다.Therefore, the noise sources should be designed to generate as little noise as possible, and if the noise is inevitably generated, measures should be taken to prevent the noise from propagating outside.

통상적인 음향차폐 방법으로서는 흡음 또는 차음 성능이 있는 소재로 만들어진 각종 방음재를 사용하여 방음벽, 방음 칸막이(partition), 방음실, 음향처리용 마감재 등과 같은 방음 구조물을 설치함으로써 소음을 흡수하고 그 전파 경로를 차단하는 방법이 널리 사용되고 있다.As a conventional acoustic shielding method, various soundproofing materials made of sound absorbing or soundproofing materials are used to install soundproofing structures such as soundproof walls, partitions, soundproof rooms, and finishes for acoustic processing, thereby absorbing noise and providing a propagation path. Blocking methods are widely used.

한편, 선박에서도 마찬가지로 기관실 등 격실 내의 공기소음은 일정 수준이상이 될 경우 승조원 청각장애를 가져올 수 있으며, 전투함의 경우 공기소음이 선체를 가진하여 수중 방사소음 및 소나 자체소음으로 전파되어 함정의 임무수행에 영향을 줄 수 있다.On the other hand, in the case of ships, the air noise in the compartments such as the engine room can cause the crew's hearing impairment if it is above a certain level. Can affect.

이러한 공기소음을 감소시키기 위하여 종래에는 흡음재가 시공된 상자 형태의 장치를 소음장비에 씌우거나, 격실 내부에 시공 또는 선체에 흡음재를 직접 부착하거나 카세트 형태의 작은 흡음판을 늑골 사이에 삽입하는 행태로 시공하고 있다.In order to reduce such noise, conventionally, a box-type device in which a sound absorbing material is constructed is applied to a noise device, a construction inside a compartment or a sound absorbing material directly attached to a hull, or a small sound absorbing plate in a cassette shape is inserted between ribs.
