An embodiment of the present disclosure provides a method for driving an acoustic transducer, including: obtaining a reference electrical signal according to a first electrical signal output by a first acoustic transducer element in a case where sound waves are not received by the first acoustic transducer element; obtaining an actual detected electrical signal according to a second electrical signal output by a second acoustic transducer element in a case where sound waves are received by the second acoustic transducer element; and performing a noise reduction process on the actual detected electrical signal according to the reference electrical signal to obtain a noise-reduced signal as a final output electrical signal of the second acoustic transducer element in a case where sound waves are received by the second acoustic transducer element. An embodiment of the present disclosure further provides an acoustic transducer.
