Welcome Technic to the Discord Family! Minecraft modders get Discord Love. A few months back the guys over at Technic started talking to us about Discord. They were early fans and after some time we decided to work with them and collaborate where it made sense.
USA: Prentice-Hall, 2002. Many animals can hear ultrasonic frequencies; dogs, for example, can hear sounds as high as 50,000 Hz, and bats can detect frequencies as high as 100,000 Hz.. Hearing Range in Animals. MSN Learning and Research. Microsoft Corporation.
So, dogs can hear sounds that human cannot, for example: bats: they use ecolocalization yelling sounds from 14 kHz to 100 kHz, so dogs hear them better than humans do. rats: they chat at ranges from 20 kHz to 50 kHz, so ratter dogs can perfectly hear them. frogs: they chat at 35 kHz, so dogs hear them too
