How to make a hurt/living sound be "following" a living entity?...

What i mean is, when i put a "long sound effect" for hurting or living sound, the sound effect gets "stuck" where they did it, if they move 30 blocks the sound effect stills playing at were they did it at first, i dont find any way to make it to be "following him", i hope someone can help me :(

i think its not audio format nor track, i already changed it from stereo to mono, and exported to ogg vorbis on audacity
