How wifi in ear monitoring works?5 answersIn-ear monitoring (IEM) systems use wireless technology to monitor and control the wearer's acoustical environment. These systems typically consist of monitors for each ear, external microphones for depth perception and directionality, and a digital wireless communication and digital signal processing (DSP) based system. The wireless in-ear monitor transmitter wirelessly transmits an audio signal to the in-ear monitor receiver, which receives and outputs the audio signal based on playback and system parameters saved in its memory. Additionally, the in-ear monitor transmitter can transmit and receive playback and system parameters from other in-ear monitor receivers, allowing for parameter checks and synchronization. This wireless communication is facilitated by a wireless communication module in the in-ear monitor device, which can transmit the temperature signals in real-time or store them for later synchronization with a computer apparatus. Overall, these systems enable real-time monitoring and control of the wearer's acoustical environment using wireless technology.
