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.
Sound waves with a high frequency have high pitches. Sound waves with low frequencies have low pitches. The human ear can hear sound energy as low as 20 Hz and as high as 20,000 Hz. The more energy sound has, the larger the wave is (higher amplitude) and the louder it is.
