Singapore firm to produce world's loudest, smallest whistle

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.
