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.
The only bird known to make use of infrasound (at about 20 Hz) is the western capercaillie. The hearing range of birds is from below 50 Hz (infrasound) to around 12 kHz, with maximum sensitivity between 1 and 5 kHz. The range of frequencies at which birds call in an environment varies with the quality of habitat and the ambient sounds.
