Background noise generally refers to the total noise except useful signals in electroacoustic system, including audio equipment noise and playback environment noise. Generally speaking, the noise floor of Bluetooth headset will be more serious.
One of the rustle of Bluetooth headsets is the inherent noise produced by components, and almost all components in the circuit will produce certain noise when working.
The rustling noise of Bluetooth headset also comes from the design error of the circuit itself or the defect of the installation process. Circuit design errors often lead to slight self-excitation of the circuit.
Extended data:
It is impossible for ordinary consumers to eliminate the inherent noise of the device itself when the Bluetooth headset has rustling noise. However, for external interference, we can solve it in some ways:
1, Pay attention to maintenance during daily use of Bluetooth headset, and don't work in harsh environment for a long time.
2. Choose a metal cabinet to carry our system, and effectively ground the metal cabinet, which can resist a lot of space radiation. In addition, the signal line and power line also adopt special shielding treatment, which can effectively eliminate electronic radiation interference.
3. Adopt AC purified power supply. Some AC purification power supplies have the functions of power factor compensation and waveform correction besides voltage stabilization and filtering.
