The present invention provides a method and apparatus for muting a sounder device, the method comprises steps of binding a network terminal with the sounder device via a network; generating a muting requirement; sending a muting signal to the sounder device via the network, the muting signal is generated based on the muting requirement; wherein the sounder device is configured to perform a muting process upon the muting signal. The method further comprises a step of sending a recovery signal to the sounder device via the network if the muting requirement becomes invalid, and the sounder device is configured to recover the status before the muting process upon the recovery signal. When it is necessary to remove unwanted background sound, all the sounder devices can be controlled via a network to perform a muting or volume-lowering process. In this way, the mobile terminal can easily and rapidly have the unwanted background sound be removed or lowered at the time of answering or making a call.
