Engage IEMs
Allowing musicians to add ambient noise back into their performance experience.
The project proposes the potential of Ambient Aperture Technology (AAT) for In-Ear Monitors (IEMs), 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. Despite semi-professional musicians looking to use IEMs, the project identifies the gap in the market for a product that meets the needs of these musicians. The environment in smaller venues in which semi-professional musicians perform imposes different requirements for the product. For example, noise levels in such venues differ to what can be assumed for larger venues, thus creating a user experience which is currently not catered for in the market.
Research proves that a leading problem experienced by the target market of semi-professional musicians is the isolation felt from ambient noise in the environment being blocked whilst wearing IEMs. The project presents the need for the proposed solution: an IEM headset containing the unique AAT, which provides a method for users to control the amount of ambient noise passing into their ear canal by the use of a rotational mechanism in the form of the IEM faceplate.
At a closed state of 0º rotation, the AAT creates a complete seal with the ear, preventing the transmission of ambient noise to the ear canal. Rotation of the faceplate to a 45º or 90º state, supported by a tactile switching feedback, allows up to 15 dB of ambient noise to be added back into the user’s mix. Careful selection of materials prevent premature failure of the mechanism within a predicted service life of 192,000 cycles and incorporates important sustainability considerations with the use of recyclable materials. Design for disassembly supports recyclability and allows repair and replacement of parts.
Testing of 3D prototypes concludes that AAT eliminates the feeling of isolation experienced in the operational environment. The solution presented to the client allows musicians to take back control of their performance experience and engage with fans and fellow band members.
