Typically, to block sound of a particular frequency, a structure of comparable wavelength dimensions is required. For low-frequency sounds with very long wavelengths, this can mean needing prohibitively large objects to reduce noise. In this episode, we talk to Trigun Maroo about his research regarding using 3d printing to create noise-attenuating structures that take up less space.
