Dans sa plus simple expression, le test acoustique consiste \u00e0 frapper d\u00e9licatement une partie de la coque ou de la structure du navire avec une pi\u00e8ce de monnaie, un petit marteau, ou n\u2019importe quel objet dur et d\u2019\u00e9couter le son qui sera g\u00e9n\u00e9r\u00e9 par l\u2019impact. <\/p>\n
En r\u00e8gle g\u00e9n\u00e9rale, le son qui r\u00e9sultera de l\u2019impact sera net et clair. Dans le cas de r\u00e9gions compos\u00e9es de bois tr\u00e8s humide ou d\u2019endroits construits en fibre de verre ou composites d\u00e9lamin\u00e9s, le son r\u00e9sultant d\u2019un impact sera sourd. Ce simple test permettra de localiser les r\u00e9gions de la coque ou du pont qui m\u00e9ritent plus d\u2019attention et des tests plus sophistiqu\u00e9s avec des instrument plus modernes comme un humidim\u00e8tre, par exemple. <\/p>\n
Les coques construites en sandwich polyester seront plus difficiles \u00e0 inspecter car l\u2019\u00e2me en mousse agira comme isolant sonore et pourrait fausser les r\u00e9sultats du test acoustique.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
