Abstract
A method and a device for adjusting frequencies of intercom apparatuses are provided. The method includes: detecting, at a current operating frequency of a first intercom apparatus, an unknown speech signal sent from an intercom apparatus other than the first intercom apparatus, the first intercom apparatus communicating with at least one second intercom apparatus associated with at least one second terminal; determining a target operating frequency; and sending a first adjusting instruction instructing the first intercom apparatus to adjust the current operating frequency to the target operating frequency; and sending a frequency changing message to the at least one second terminal for controlling the at least one second intercom apparatus to adjust the current operating frequency to the target operating frequency.
