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.
At peak functioning, human ears can hear sounds at frequencies up to 20 kilohertz. Depending on size, breed, and age, the high end of a dogâs hearing ranges from 40 up to 60 kilohertz. The sound of the typical ultrasonic dog whistle varies between 23 and 54 kilohertz. Dog whistles work in the same ways that any other modes of training do, and for the same reasons; to wit, dogs are consistently trained to respond in a certain fashion to their use.
