Abstract
An internal combustion engine element may be an air filter or a suction system of an internal-combustion engine. Both have a housing with walls which bound an interior of the housing, through which interior intake air flows during the operation of the internal-combustion engine. For achieving advantageous psycho-acoustic effects, the walls are provided with relatively thin-walled surfaces for achieving defined frequencies.
