The U.S. Navy said it awarded Rancho Bernardo-based LRAD Corp. an indefinite-delivery, indefinite-quantity contract for acoustic hailing devices. The deal could be worth as much as $12.2 million over five years.

LRAD’s electronics produce very loud, very directional sound, and can amplify a voice so it can be heard over a very long distance. The sounds can also cause pain, helping the Navy provide force protection, a military term for protecting surface ships, submarines, security boats and shore security operations.

Under the deal, LRAD will provide small, medium and large acoustic hailing devices, mounts, test teardown and evaluation, spares and data.

Three companies bid on the contract, awarded by the Naval Surface Warfare Center of Crane, Ind.
