Heroes: Enhanced Hearing

Enhanced hearing is the ability to hear sounds beyond normal limits.

Characters

 * Dale Smither was the first character to display this ability.
 * Sylar stole this ability from Dale but lost it after being infected by the Shanti virus.

Dale Smither
Enhanced hearing appears to be a passive ability which is always active, yet controllable. With some concentration, the user can isolate particular sounds.

Dale had at least enough sensitivity to hear a human heartbeat from a few feet away. She had enough practice to detect changes in a person's mood by changes in their heart rate. She claimed to be able to hear every individual footfall of a cockroach.

Sylar
Sylar experienced some difficulty controlling the power after first obtaining it. He was sensitive to loud noises, such as a car door being slammed, which produced flinches and enough pain to make him groan. Mohinder was able to use this sensitivity against Sylar and torture him with a tuning fork.

Currently, Sylar seems to display mastery over the ability. He was able to eavesdrop from across Kirby Plaza, as well as detect Hiro's beating heart from several meters away and later recognize it. He also claimed to be able to hear a pin drop from a mile away.
