Figure 4 shows the block diagram of the BGT60LTR11AIP monolithic microwave integrated circuit (MMIC). The integrated voltage-controlled oscillator (VCO) generates the high-frequency signal, which is stabilized by a phase-locked loop. Moreover, the transmitter section consists of a medium-power amplifier with configurable output power. It can be controlled via the serial peripheral interface (SPI), while integrated power detectors monitor the transmitted power.

Headphones, by design, isolate wearers from the outside world. While this can provide valuable passive isolation from annoying sounds, it is not always convenient. In many situations, we also want to hear what’s going on around us without having to remove our devices — for instance, to tune in to announcements in train stations, pick up on surrounding sounds while running in a park, or talk to others. Transparent hearing modes have been developed that enable users to create blended augmented audio experiences by telling their high-performance microphones how much of the outside sound environment they wish to capture. Sound is picked up just before it enters the ears and is altered and played back in real time, creating a transparent, augmented hearing experience. Some manufacturers provide smart features, such as the automatic activation of transparent hearing when the wearer’s name is called. In the future, it may be possible for microphones to be activated automatically when they detect an approaching car or a boarding announcement in an airport, for instance.
