The Newcastle boss appeared in front of a three-man independent regulatory commission, where he is understood to have made a personal statement, and must now wait to find out what punishment the FA will hand down.
League Manager's Association (LMA) chief executive Richard Bevan was also in attendance to observe proceedings.
The charge followed the confrontation during United's 4-1 win at the KC Stadium on 1 March when Pardew butted Meyler on the touchline after the midfielder tried to retrieve the ball from the Newcastle technical area.
Match referee Kevin Friend cautioned Meyler for his part in the incident and then sent Pardew to the stands, from where he watched the remainder of the game.
In the hours immediately after the match, Pardew made a public apology for his behaviour, while he was fined £100,000 by his club and issued with a formal warning.
The commission can take previous offences into consideration - Pardew was given a two-match touchline ban and £20,000 fine in August 2012 for pushing an assistant referee.
He was also warned about his future conduct by the FA in January this year following an angry exchange when he was caught on camera swearing at Manchester City boss Manuel Pellegrini.
