A tunable acoustic barrier based on periodic arrays of subwavelength slits

A tunable acoustic barrier based on periodic arrays of subwavelength slits

The most usual method to reduce undesirable enviromental noise levels during its transmission is the use of acoustic barriers. A novel type of acoustic barrier based on sound transmission through subwavelength slits is presented. This system consists of two rows of periodic repetition of vertical ri...
