The invention provides a polytetrafluoroethylene spun-fiber waterproof acoustic-transmission membrane and a production method thereof. The polytetrafluoroethylene spun-fiber waterproof acoustic-transmission membrane comprises a polytetrafluoroethylene spun-fiber membrane and double-sided adhesive tape adhered to edges on two sides of the polytetrafluoroethylene spun-fiber membrane. The productionmethod includes: producing the polytetrafluoroethylene spun-fiber membrane through an electrostatic spinning method; producing the polytetrafluoroethylene spun-fiber waterproof acoustic-transmission membrane. The microstructure of the polytetrafluoroethylene spun-fiber membrane produced through an electrostatic spinning method is characterized in that polytetrafluoroethylene spun-fibers are stacked, molecular chains on nodes among the fibers intertwine, and the microstructure is less prone to deformation when being impacted by water. The polytetrafluoroethylene spun-fiber waterproof acoustic-transmission membrane produced by the polytetrafluoroethylene spun-fiber membrane is high in tensile strength, stable in structure, good in applicability and excellent in waterproof and acoustic-transmission performance, the optimal waterproof grade of the polytetrafluoroethylene spun-fiber waterproof acoustic-transmission membrane is IPX6/IPX8 (multipurpose), and the maximum loss of sounds with the frequency being 5kHz is 6dB.
