Shortly after a forced go around to traffic touching down from an erroneous ASDE (Airport Surface Detection Equipment) alert an Aircraft departed on an assigned heading of 340 on a radar vector. I thought the pilot read back correct heading. I noticed the pilot had turned east just shortly after departure. I turned the pilot back to the west but they were already below the Minimum Vectoring Altitude (MVA). The pilot was eventually turned to a correct heading outside of the MVA. There was a lot of back ground noise in the tower cab due to a fan that had to be placed in the cab due to the air conditioning not working correctly. Also working on disseminating information from the previous ASDE alert may have caused to miss the correct heading read back. I tried to listen to the audio but the FALCON replay would not load the audio. Fix the air conditioner to avoid excess noise.
Tower Controller reported they missed an aircraft reading back the wrong turn direction due to noise from a fan and the aircraft flew below the Minimum Vectoring Altitude.
