Fear of Sound
by Sylsatra
Fear of Sound is a Forge mob mod in which creatures react to nearby noises by fleeing, hiding, freezing or playing dead instead of running away.
What it does
Creatures listen for sounds around them and treat loud or close noises as threats. Their AI detects the source, then pathfinds away from it or looks for cover, so mobs can freeze or hide when danger is near. Some animals, such as the fainting goat, play dead instead of fleeing. A scent awareness feature lets mobs pick up on smells, which adds another signal alongside sound.
The mod is aimed at players who want stealth and immersion in mob behavior, and at server owners who want creatures to influence how a world plays. Fear of Sound needs Quantified API. Attract to Sound is an optional companion and works on Forge, NeoForge and Fabric as a sound and stealth counterpart. Fear of Sound runs on client and server, so the server and every player need it. It is released under the GNU General Public License v3.0 or later, is open source, and targets 1.20.1 only, with the latest Forge build 3.0.0 from 2026-10-13.
Key features
Adaptive fear system
Mobs adjust how strongly they react to a sound depending on its distance and the situation around them.
Hide, freeze and play dead
Instead of running, creatures can take cover, stand still or, for some species, faint in place when a threat is nearby.
Scent awareness
Mobs can detect nearby scents, so a noise is not the only cue that makes a creature react.
Advanced fear rules
Rules control which mobs fear which sounds, and a bypass system lets specific cases skip the normal reaction.
Configurable behavior
Most fear settings can be changed in the config, and built-in support covers other mod content.
Performance caching
Results of sound and path checks are cached so the extra AI runs without slowing a busy world.
