is it louder than the hyperwhistle

Haven’t tried hyperwhistle, and as I mainly referee on local parks it’s hard to determine the difference between, the acme t2000, and the fox supersonic.

Mine came in Japanese packaging. Did i get an authentic one?

All of mine bought from a local reseller popular with North TX referees are made in Japan. Knockoffs generally come from China with names like “Volteen”. The reliability and performance of the Valkeen is worth it. I only have to replace mine when I lose one. During tournaments I can accidentally stop play on nearby fields with a hard whistle.

Is it louder than the Fox 40?

I’ve seen people test it with professional instruments on YouTube. The loudest fox 40 is 121db tested, and the valkeen is 126db tested. The best selling fox 40 classic is 117db tested for reference.
