The estimation of an HRTF for a given individual is accomplished by means of a coupled model, which identifies the dependencies between one or more images of readily observable characteristics of an individual, and the HRTF that is applicable to that individual. Since the HRTF is highly influenced by the shape of the listener's outer ear, as well as the shape of the listener's head, images of a listener which provides this type of information are preferably applied as an input to the coupled model. In addition, dimensional measurements of the listener can be applied to the model. In return, the model provides an estimate of the HRTF for the observed characteristics of the listener.

A custom-fitted helmet and a method of making the same can comprise, at a first location, obtaining head data for a customer's head comprising a length, a width, and at least one head contour. With at least one processor, generating a computerized three-dimensional (3D) headform matching the customer's head length, width, and head contour from the head data. The 3D headform can be compared to a helmet safety standard. At a second location different from the first location, a custom-fitted helmet based on the 3D headform can be formed, wherein the custom-fitted helmet satisfies the safety standard and comprises an inner surface comprising a topography that conforms to the length, width, and at least one contour of the customer's head. The first location can be a home or a store. Obtaining the head data from photographic images of a deformable interface member disposed on the customer's head.

A helmet construction for protecting a user's head, and the brain within the cranium from impact forces, includes a shell contoured to the shape of the user's head, with cushioning along at least part of the shell interior and a chinstrap. The shell consists of three (or more) discrete panels that are physically and firmly coupled together providing rigid protection under most circumstances, but upon impact the panels move relative to one another, but not relative to the user's head, thereby permitting impact forces to be dissipated and/or redirected away from the cranium and brain within. Upon impact to the helmet, there are sequential stages of movement of the panels relative to each other, these movements initially being recoverable, but with sufficient vector forces the helmet undergoes structural changes in a pre-determined fashion, so that the recoverable and permanent movements cumulatively provide a protective ‘crumple zone’ or ‘shear zone’. The first two stages of protection arise from the design of the fasteners that have the ability to invaginate and collapse within themselves, and their design having a 45 degree angle, which will allow movement of a region of connected panels to translate along the fastener shaft. Both of these movements will be recoverable and provide a ‘functional crumple zone’. The final stage of protection arises from the braking function of the pins, as they are forced from one aperture through to the next, the direction and extent of which is determined by the impact force and direction. This final level of panel movement and protection is not recoverable and thus provides a ‘structural crumple zone’. Finally the fastener size and thickness, together with the thickness of webbing and distance between apertures, functions to provide varying degrees of resistance to impact forces, thus making the helmet design suitable for activities with different levels of impact speed and risk potential.
