Engage In-Ear Monitors (IEMs) incorporate unique Ambient Aperture Technology (AAT), to be used on stage by musicians during performances and sound checks. Compared to wedge monitors, IEMs allow reduced feedback and stage noise, more control over the user’s personal mix and, overall, an improved relationship between a musician and their music.

Research proves that a leading problem experienced by the target market of semi-professional musicians is the isolation and occlusion experienced from ambient noise in the environment being blocked whilst wearing IEMs. The developed AAT provides a method for users to control the amount of ambient noise passing into their ear canal via rotational motion of the IEM faceplate. AAT eliminates isolation in the operational environment and improves perceived acoustics and tuning. The solution presented to the client allows musicians to take back control of their performance experience and engage with fans and fellow band members.
