There is noise in the living room family hospital hospital, which is getting louder and louder, how

Generally speaking, the audio is mostly active speakers, and there must be amplifiers inside, so noise is inevitable, and the noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise according to the source.

Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the power transformer interference is caused by the magnetic leakage of the power supply of the multimedia speaker, and the effect of installing a shielding cover for the transformer is very obvious when conditions permit, which can block the magnetic leakage to the greatest extent, and the shielding cover can only be made of iron materials. We should try to choose products with big brands and solid materials, and in addition, using external transformers is also a good solution.

Stray electromagnetic interference is common, and speaker wires, crossovers, wireless devices, or computer hosts can all become sources of interference. Keep the main speaker as far away from the computer as possible and reduce the number of peripheral wireless devices.
