SINGAPORE - IPS Securex Holdings, a security products firm listed here, aims to make and sell the world's smallest and loudest whistle in Asia.
The HyperWhistle will generate an ear-piercing 140 decibels, markedly louder than a typical car horn at 110 decibels.
In a statement to the Singapore Exchange on Tuesday, IPS Securex said one of its subsidiaries has signed a memorandum of understanding with two United States firms, United Tactical Systems and Wattre Corporation to work on the project.
