While travelling at speed, wind noise can pose a damaging threat to the hearing of motorcyclists. Hearing damage is particularly prevalent in occupational riders, such as emergency service riders. The Lenza One was designed with a key focus on reducing in-helmet noise. Aimed primarily at occupational riders, it has several features which enable the reduction of wind noise. The rider will experience both a reduced risk of hearing damage and a heightened awareness while riding. The noise reduction is enabled through the dimpled surface and suspended shell. The elongated shape also contributes to ability to reduce wind noise.

The project itself is my final year project, for a Product Design degree at the University of Brighton.

Wind tunnel tests are currently under way to determine the degree of noise reduction capable. Initial tests showed the concept has potential in doing so.

The design itself was modelled in Solidworks.

The prototype was 3D printed.

The shell was prepared and painted, with other components and accessories manufactured. The visor was cut from a flat sheet of acrylic, heated and moulded around a former.

Finished article.
