Narrative:
After we were given clearance to intercept the localizer at 3000 ft. We lost communication with approach control. The first officer; who was the pilot flying; maintained the last assigned course and altitude while we tried to reestablish communications. The captain tried to contact the tower while I tried to contact ground control on the the other radio. We then switched the radio back over to guard; and I heard a controller giving us instructions of maintain our altitude and turn to a heading. I responded to the instruction and realized the captain or [flying] first officer had not heard the new clearance. I proceeded to inform them of the instruction; and switched the captain's radio to the guard frequency. Upon further investigation we found out that during the turbulent weather we were encountering; the captain's hand mike had fallen out of its cradle; and had gotten lodged in a way to cause a stuck mike.
