The utility model discloses an intake and exhaust silencer. The air intake and exhaust silencer is communicated with an air compressor and is suitable for reducing noise in the air intake and exhaust process of the air compressor, the air intake and exhaust silencer comprises a silencer body and at least one separator, the silencer body forms an air guide channel, the air guide channel is provided with a first air port and a second air port, and the first air port and the second air port are communicated with each other. The air guide channel is communicated with the air compressor and used for guiding air sucked or exhausted by the air compressor. The partition pieces are arranged in the air guide channel, at least one partition piece divides the air guide channel into at least two silencing chambers, each partition piece is provided with a communication channel, and every two adjacent silencing chambers are communicated through the corresponding communication channel, so that when noise enters the air guide
