LRAD Corp. says it has received $700,000 in orders from an unnamed country in Southeast Asia.

The business makes mass notification systems and acoustic hailing devices — essentially loudspeakers that can send intelligible sound in one direction for greater than 3 miles. LRAD’s electronics are up to 10 times louder than bullhorns and vehicle public address systems, the business said.

In its Sept. 14 announcement, LRAD (Nasdaq: LRAD) said its customer was in public safety and law enforcement, and was a repeat buyer. “After evaluating other products, our customer again selected LRAD for its superior broadcast range, vocal clarity and durability,” CEO Richard Danforth said in a prepared statement.
