| Sumario: |
The ultrasound wave transmission between human tissue layers was investigated in this project, aiming for a focal stimulation of the auditory nerve on the cochlea. A simulation of the transmission was implemented with the boundary element method in order to visualize the behavior of the ultrasound wave. The ear and some basic information about its function are presented. Some acoustic parameters for the boundary conditions are written. The results obtained show transmission between layers and a 30 dB attenuation on the cochlea caused by the transmission. It is proposed a source array with multiple ultrasound sources, using phase differences between the sources to focus this way the area desired for stimulation, because the results with one acoustic piston source, producing a plane wave are not satisfactory for a focused stimulation.-- Grupo GIMSC.-- Línea de Investigación: acústica y procesamiento de señales.-- Área: acústica.-- Tema: ultrasonido |
