Measuring the effects of head and neck support systems on signals transmitted to the ear.
Some individuals with motor control problems require head and/or neck support systems to achieve proper positioning in their wheelchairs. Signal transmission to a KEMAR positioned in a wheelchair with three commonly used support systems was evaluated with a probe microphone system. The three systems created different patterns of shadow and baffle effects. Audiologists are advised to evaluate the acoustic impact of the specific support systems used by their patients.
